The Maldives (Dhivehi: ދިވެހިރާއްޖެ Dhivehi Raajje) are an archipelago of 1,192 coral islands grouped into 26 coral atolls (200 inhabited islands, plus 80 islands with tourist resorts) in the Indian Ocean. They lie south-southwest of India and are considered part of South Asia.
The Maldives are formed of 26 atolls, or atholhu in Dhivehi — the source of the English word. These are not single islands, but giant ringlike coral formations hundreds of kilometres wide that have fragmented into countless islands.
Atoll naming is complex, as the atolls have both lengthy traditional Dhivehi names like Maalhosmadulu Dhekunuburi, and snappy code names like Baa that refer to administrative regions and may consist of more than one geographical atoll. The code names are actually just the letters of Dhivehi alphabet, but being easier for non-Maldivians to remember and pronounce, the code names are popular in the travel industry and are hence also used here. Of the 20 administrative atoll groups, only (parts of) 10 are open to tourism, and from north to south these are:
|Lhaviyani (Miladhunmadulu Uthuruburi)|
|Raa (Maalhosmadulu Uthuruburi)|
|Baa (Maalhosmadulu Dhekunuburi)|
|Kaafu (North and South Male Atoll)|
Site of the capital Male and the airport, home of most Maldivian resorts.
To the west of Kaafu, the second most popular group.
|Faafu (Nilandhe Atholhu Uthuruburi)|
|Dhaalu (Nilandhe Atholhu Dhekunuburi)|
The southernmost atoll, the second-largest in population and site of Gan International Airport.
The other atolls are Gaafu Alifu, Gaafu Dhaalu, Gnaviyani, Haa Alifu, Noonu, Haa Dhaalu, Laamu, Nyavinani, Shaviyani and Thaa.
- 1 Male — the capital and largest city
- Seenu — second-largest city and short-lived home of the Suvadive secessionist movement
- 1 Kuredu — one of the inhabited islands of Lhaviyani Atoll
- 2 Mathiveri — island belonging to North Ari Atoll
- 3 Rasdhoo — smallish inhabited island and the capital of the North Ari Atoll
- 4 Thoddoo — an isolated inhabited island that administratively belongs to North Ari Atoll. It's also the largest producer of watermelon in Maldives.
- 5 Ukulhas — smallish 1 km long island of Alif Alif Atoll

Formerly a Sultanate under Dutch and British protection, the Maldives gained independence from the British in 1965, and became a republic in 1968. Maumoon Abdul Gayoom ruled over the country with an iron fist, and did not hesitate to jail dissidents, He was re-elected five times in more or less rigged elections. Resistance to his rule culminated in violent rioting in 2003 and 2004. Much to everybody's surprise, free and fair elections were held in 2008, and Gayoom conceded defeat to opposition leader Mohamed Nasheed, "Anni". By December 2011, though, the tables had turned. Most of Nasheed's allies had left his government and there were increasingly large anti-government protests. Nasheed resigned in 2012 under murky circumstances and then lost a controversial 2013 election to Gayoom's half-brother Abdulla Yameen, whose administration has cracked down on political freedom and imprisoned opposition figures. Nasheed was granted asylum in the UK, but hopes for democracy in the Maldives have been crushed.
The tsunami of 26 December 2004 caused extensive damage to the Maldives - of a population of only 290,000, over a third was directly affected by the tsunami and more than 15,000 people were left homeless. The economic damage alone was over 62% of the GDP or US$470 million. The immediate response from international donors and agencies mobilized more than US$400 million in aid after the disaster, much of which was used to help misplaced persons rebuild their homes and infrastructure damaged by the waves. As of 24 December 2010, six years after the tsunami, the number of people living in temporary shelters had fallen from 15,000 to 1,600 people.
Tourism, Maldives largest industry, accounts for 20% of GDP and more than 60% of the Maldives' foreign exchange receipts despite the country's stance of legally-entrenched discrimination against non-Muslims. Over 90% of government tax revenue comes from import duties and tourism-related taxes. Over a million tourists visited the islands in 2013. Fishing is a second leading sector. The Maldivian Government began an economic reform program in 1989 by lifting import quotas and opening some exports to the private sector. Subsequently, it has liberalized regulations to allow more foreign investment. Agriculture and manufacturing continue to play a minor role in the economy, constrained by the limited availability of cultivable land and the shortage of domestic labour. Most staple foods must be imported. Industry, which consists mainly of garment production, boat building and handicrafts, accounts for about 18% of GDP. Maldivian authorities worry about the impact of erosion and global warming on their low-lying country; 80% of the area is one metre or less above sea level.
Maldivians are almost entirely Sunni Muslim, and the local culture is a mixture of South Indian, Sinhalese and Arab influences. While alcohol, pork, dogs and public observance of non-Muslim religions are banned on the inhabited islands, the resort islands are allowed to exist in a bubble where anything goes.
Note that the weekend in the Maldives runs from Friday to Saturday, during which banks, government offices and many shops are closed. You won't notice this at the resorts though, except that lunch hours may be shifted for Friday prayers.
The Maldives are tropical, with plenty of sunshine and temperatures around 30°C (86°F) throughout the year. However, rainfall increases considerably during the April-October southwest monsoon, particularly from June to August.
- The Maldives: Islamic Republic, Tropical Autocracy by J. J. Robinson, a journalist who lived in the Maldives through some of its 21st-century political turmoil. In addition to an interesting look at what life is like for foreigners in Malé and for staff behind the scenes at the resorts, the book gives a detailed and surprisingly readable account of the complex political crises that the country experienced between 2008 and 2015.
The Maldives have a remarkably easy visa policy: Everybody gets a free 30-day visa on arrival, provided that they have a valid travel document, a ticket out and proof of sufficient funds, defined as either a confirmed reservation in any resort or US$25/day in cash. This can be extended up to 90 days at Male, but you'll need to indicate where you're staying for that long. See the Department of Immigration and Emigration website for details.
The Maldives is an Islamic country. Importing the following is prohibited: Alcohol, pork and pork by-products, religious articles other than Islamic ones, narcotics and psychotropic drugs, pornography (very broadly defined)
Note: all luggage is X-rayed on arrival. Exporting sand, seashells or coral is also forbidden.
Practically all visitors arrive at Malé International Airport (MLE IATA), located on Hulhulé Island right next to the capital Male. The airport is served by a wide array of flights to China, India, Sri Lanka, Dubai and major airports in South-East Asia, as well as an increasing number of charters from Europe. Many flights stop in Colombo (Sri Lanka) on the way.
Departure taxes are included in your ticket.
British Airways now flies directly from London Gatwick to Male during the winter (October to March). No direct flights operate from London Heathrow, however it is possible to get an indirect flight via India or the UAE for example.
Singapore Airlines flies daily direct from Singapore to Male, with late night timings.
There are no regular passenger boats to the Maldives. Even yachts usually steer clear, as navigating around the reefs is hazardous and permits are expensive.
Getting around in the Maldives takes three forms: boats, sea planes (air taxis) and private yachts. The boats are the Maldivian equivalent of a car, while planes and private yachts are mainly reserved for tourists.
Air taxis and boats prefer not to operate at night, so if you arrive at the airport after dark and are going to a distant resort, you may have to spend the night in Male or at the airport hotel in Hulhule. Private transfers, though expensive can be opted for resort transfers, instead of spending the whole night at Male. Private transfers could cost US$500-800. On the way back, there may also be a significant gap between the time your transfer arrives and your flight departure. Check with your resort or travel agent.
No point in the Maldives is more than 90 minutes away by plane from Male, and visitors to the more far-flung resorts use air taxi services. As of 2013, the only operator is Trans Maldivian Airways, which flies DHC-6 Twin Otter seaplanes that take around 15 passengers.
The taxi boats generally take tourists to and from the islands in the North and South Male atolls. They come in all different shapes and sizes depending on the quality of the resort you stay, and the Four Seasons has a large enclosed motor cruiser with drinks and food, while the lesser resorts have open sided dhoni fishing boats.
Public dhoni ferries and cargo boats are available for more the independent-minded and budget-conscious. The main operator is MTCC, who list schedules and fares on their website.
The previous system of requiring written invitations and Inter Atoll Travelling Permits (IATP) for those wishing to visit other islands has been abolished, you're now free to travel wherever you wish. IATPs are still required if you wish to dock your own yacht, see Customs for details.

Maldivian Dhivehi, a close relative of Sinhala (spoken in Sri Lanka) but with borrowings from Urdu, Hindi, Arabic and many other languages, is the official language. It is written in a remarkable hybrid script called Thaana, which uses Arabic and Indic numbers as the base of the alphabet, written from right to left with Arabic vowel signs. The script is thought to have originated as a secret code for writing magical formulas so that outsiders can't read them, which would also explain why the ordering of the alphabet is, as far as linguists can tell, random.
English is widely spoken, particularly by government officials and those working in the tourism industry. English is also the language of instruction in schools. "House reef" describes a coral reef accessible from the beach or jetty, thus you may hear discussions about whether an island has a good house reef or not.
Since Maldives are a a popular destination for German and Italian holiday makers, a sizeable number of local resort workers speak German and Italian. This may vary depending between resorts.
Most visitors come to enjoy the countless plush resorts, excellent beaches and stunningly colourful underwater life. Due to the isolated position of the island, the number of animals on land is limited, but just under the surface of the beautiful blue ocean there's a wealth of wildlife to see. Over 2000 species of fish in all colours of the rainbow roam the clear waters around the islands. You will likely see plenty of anemones, different kinds of rays, octopus, squid and even giant clams. Whales, dolphins and turtles are spotted often. The Baa Atoll, named a UNESCO World Biosphere Reserve in 2011 and one of the richest coral reefs in the world, is becoming a main tourist draw while also becoming an example of sustainable tourism in a protected area. In short; snorkeling or diving is an absolute must, see the Do-section below for more information.
The gorgeous and ubiquitous white sand beaches are a sight by themselves, especially with the tropical island setting they are in. A flight to one of the many resort islands gives spectacular aerial views of these picture-perfect islets, defined by rims of white sand and wide strokes of cobalt blue water.
Yet, if you can pull yourself away from your luxury holiday spot, the capital Malé is a pleasant diversion. The bustling financial and political centre of the country has a few sights. Try the National Museum for a touch of history. While the building may not look too promising, the museum's fine collection includes beautiful Arabic- and Thaana-engraved wood works, religious pieces, weaponry and other historic artefacts. The town also has a number of worthwhile mosques. The 17th century Old Friday Mosque is the oldest one in the country, and officials are often willing to let polite and properly dressed visitors in. The Grand Friday Mosque & Islamic Centre is its 1984 modern counterpart, and dominates the city's skyline. While simply in design, the large, white marble structure and shining gold dome is an attractive sight.
Diving and snorkelling
Aside from making the water bungalow rock on your honeymoon, the primary activity on the Maldives is scuba diving. The atolls are all coral reefs hundreds of kilometres away from any major land mass, meaning that water clarity is excellent and underwater life is abundant. Manta rays, sharks, even a few wrecks, you name it, you can find it in the Maldives.
While diving is very good by world standards even in the immediate vicinity of Male, visibility and the chance of encountering large pelagic fish increases as you head to the outer atolls. Many divers opt for live-aboards, which can work out much cheaper than paying high resort fees. Currents vary considerably, with generally little inside the atolls but some powerful streams to be found on the sides facing the open sea. Water in the Maldives is warm throughout the year and a 3 mm shorty or Lycra diveskin is sufficient. Diving is possible throughout the year, but rain, wind and waves are most common during the season of the southwest monsoon (June-August). The best time for scuba diving is from January to April, when the sea is calm, the sun is shining and the visibility can reach 30 m. There are decompression chambers on Bandos in Kaafu (15min from Male), Kuredu in Lhaviyani Atoll and at Kuramathi on Alifu.
The one downside to diving in the Maldives is that it's quite expensive by Asian standards. Prices vary considerably from resort to resort, with specialist dive resorts offering better prices. In general, a single boat dive with your own gear cost around US$50, and US$75 without. Beware of surcharges: you may be charged extra for boat use, guided dives, larger tanks, etc. On the upside, safety standards are usually very high, with well-maintained gear and strict adherence to protocol (check dives, maximum depth, computer use, etc.) being the rule rather than the exception.
The Maldives is becoming an increasingly popular surfing destination. Turquoise water and perfect waves makes it an ideal and un-crowded destination for surfers looking for smooth surfing conditions.
The best period for surfing in the Maldives is between March and October; the biggest waves occurring in June, July and August. This paradise is exposed to the same swells as Indonesia is, except that its higher latitude and its South-East exposure offers cooler and less hardcore surfing. The recent O’Neil Deep Blue Contests held in the Maldives has placed Maldives firmly on the world’s surf map. While most of the recognized surf breaks are in Male’ Atoll, there is certainly more to be discovered.
Specialized companies organize tailored multi-day boat trips in the region, allowing surfers to move easily from one point to another and maximizing the surfing time.
Exchange rates for Maldivian rufiyaa
As of October 2018:
Exchange rates fluctuate. Current rates for these and other currencies are available from XE.com
The local currency is the Maldivian rufiyaa, denoted by the symbol "Rf" or "MFR" (ISO code: MVR). It is divided into 100 laari. However by law, resorts price services in US dollars and require payment in hard currency (or credit card), so there's no need to change money if you're going to spend all your time at the resorts. Most hotels have a shop but this is limited to diving and holiday essentials (sun cream, sarongs, disposable cameras, etc.) Some excursions from resorts will take you to local islands where there are handicraft type things to buy, but they are typically made outside the Maldives and sold at significant markups.
If you are heading to Male or the other inhabited atolls, exchanging some rufiyaa will come in handy. The coins, in particular, are quite attractive and make an interesting souvenir in themselves, but the smaller denominations are rarely used or seen. The rufiyaa is tied to the US dollar with in a 20% band, but is practically 15:1. US dollars are near-universally accepted: shops usually exchange them at 15:1 or 10:1.
Tipping is not compulsory in the Maldives as a 10% service charge is added to everything, although it is not certain that the money is passed on to the staff.
Over the years the tipping culture has changed in the Maldives, mainly due to overseas visitors giving varying amounts of cash as tips.
Maldives are expensive for those who have comfort- and service-oriented tourism in mind. Resorts have a monopoly on services for their guests and charge accordingly: for mid-range resorts, €942 (US$1000) per week per couple is a conservative budget for meals, drinks and excursions, in addition to the cost of flights and accommodation. Practically anything, including hotel rooms if booked locally, has a 10% "service charge" added, but tips are expected on top.
For an adventurous who has time, Maldives can be a very affordable and rewarding experience, with prices comparable to Malaysia. A number of inhabited islands have guesthouses with typical prices €25-40 per room. On more remote islands, renting rooms in villages is possible at even less. Food is inexpensive, and fish curries are delicious. Public ferries will transfer you between different islands of the same atoll for a few US dollars (though for less obvious locations, there will typically be 1 ferry per day and no ferries on Fridays). For transfers to remote atolls, one can negotiate with cargo boats, which would often take people for €14-38, depending on the destination. Cargo boats do not have schedules and depart when loaded. One may expect 1 boat in 1-3 days for each atoll.
It is important to have in mind that staying on inhabited islands implies respecting the strict Muslim norms including no alcohol, modest dress, reserved behaviour. However, the locals are very welcoming and the experience may be much deeper and more rewarding than staying in resorts.
All the resorts are self-contained so they have at least one restaurant, which generally serve the type of cuisine expected by their guests (i.e. modern European or generic Asian). Breakfast is almost always included, and most resorts offer the option of half-board, which means you get a dinner buffet, and full board, which means you get a lunch and dinner buffet. These can limit the damage compared to ordering a la carte, but your options are typically very limited and drinks are often not covered, not necessarily even water. If you're planning on drinking a lot, it may be worthwhile to go all inclusive, but even this typically restricts you to house drinks.
The only other place to find food is Male. This comes in two forms. Either small restaurants aimed at the tourists (of which there are a couple of nice Thai restaurants), which are often expensive, or small cafes called hotaa, selling local Maldivian food at prices as low as Rf20 (US$6) for a complete meal.
Maldivian food revolves largely around fish (mas), in particular tuna (kandu mas), and draws heavily from the Sri Lankan and south Indian tradition, especially Kerala. Dishes are often hot, spicy and flavoured with coconut, but use very few vegetables. A traditional meal consists of rice, a clear fish broth called garudhiya and side dishes of lime, chili and onions. Curries known as riha are also popular and the rice is often supplemented with roshi, unleavened bread akin to Indian roti, and papadhu, the Maldivian version of crispy Indian poppadums. Some other common dishes include:
- mas huni — shredded smoked fish with grated coconuts and onions, the most common Maldivian breakfast
- fihunu mas — barbequed fish basted with chili
- bambukeylu hiti — breadfruit curry
Snacks called hedhikaa, almost invariably fish-based and deep-fried, can be found in any Maldivian restaurant.
- bajiya — pastry stuffed with fish, coconut and onions
- gulha — pastry balls stuffed with smoked fish
- keemia — deep-fried fish rolls
- kulhi borkibaa — spicy fish cake
- masroshi — mas huni wrapped in roshi bread and baked
- theluli mas — fried fish with chili and garlic
As the Maldives are Muslim, alcohol is banned for the local population. However, nearly all resorts, live-aboard boats and the Hulhule Island Hotel (on the same island as the airport) are licensed to serve it, usually with a steep markup. Expatriate residents have an allowance that they can use in Malé.
Maldivians generally do not drink alcohol although this is less true of the younger generation. They are, however, unhappy about being filmed or photographed while drinking.
Tap water in resorts may or may not be drinkable: check with the management. Bottled water is extortionately priced, with US$5/bottle being typical.
|This guide uses the following price ranges for a standard double room:|
The Maldives had a longstanding policy of keeping tourists on dedicated islands, which meant they could only stay in full-service resorts where the cost of a night's accommodation started around US$200 and went up into the stratosphere, and the vast majority of visitors continue to opt for these. However, the brief democratic blossoming under Mohammed Nasheed's rule from 2008 all the islands were opened to tourism, and backpacker-friendly guesthouses starting from US$30 a night opened on inhabited islands across the archipelago.
Most resorts take up their own island (1500 x 1500m to 250 x 250m), meaning that the ratio of beach to guests must be one of the best in the world and it is hard to imagine that you would ever have to struggle to find your own private piece of beach to relax on. Many have a "no shoes" policy and with such soft sands it is easy to love this idea.
The range and themes or the resorts is impressive, and most people will find one they like. They can be grouped into three types:
- Dive resorts, designed primarily for divers. Geared expressly for people who want to spend most of their time underwater, facilities on land are limited, but the house reef is usually excellent. Often found in the more far-flung parts of the archipelago.
- Holiday resorts, designed primarily for families. These are large and have a full complement of facilities (several restaurants, day-care centres, etc.), but don't have over-the-top luxury and have less privacy. Most of these are located on Kaafu, with easy access from Male.
- Luxury resorts, designed primarily for honeymooners and the jet set. The place to be if you want designer furniture, gourmet food and a plasma TV in an overwater villa reachable only by rowboat, and are willing to pay high prices for the privilege.
A Maldivian classic is the overwater bungalow, built on stilts directly above a lagoon. While these look fabulous and sound appealing, they have their downsides:
- They're usually packed tightly together, often sharing a wall, meaning little privacy.
- Especially at low tide, the water level may be too low to allow swimming or snorkelling.
- Resort facilities may be a fair distance from the bungalows.
- The lapping of waves is romantic enough on a calm day, but can make it next to impossible to sleep if a storm blows through.
These factors vary from resort to resort, so research carefully. A good one is definitely worth trying at least once, but many Maldives repeaters prefer a bungalow with a private beach.
When considering where to go, factor in transport time and costs from the airport: the more far-flung resorts generally require an expensive seaplane transfer and you may have to stay overnight at the airport on the way. On the upside, the further away you are from Malé, the more peaceful the islands and the better the diving.
Many resorts, especially the smaller dive-oriented ones, cater largely to a single nationality, leading to "Italian" resorts, "Dutch" resorts, "German" resorts, etc. While almost all welcome any nationality and have some English-speaking staff on hand, you may be cut off from any evening entertainment and have problems e.g. diving if you don't speak the local lingo.
There are guesthouses on inhabited islands, and Maafushi island is popular with looking for hassle-free accommodation of this type. Low end prices are €25-35 per night.
Examples include: Equator Village on Addu Atoll, a former British Royal Air Force base converted to a 78-room hotel. The cost is around US$100-150 per person per day all inclusive (including some alcohol). Another unique location is Keyodhoo Guest House, this guest house is on top of a recreation centre built by an Australian after the tsunami (US$20 pp/per night). Most visitors are scuba divers or adventure travellers. Other Inns/B&B can also be found on Vaavu Atoll, Dhaalu Atoll, Kaafu Atoll, North/South Male Atoll and Ari Atoll Haggnaameedhoo. Only a few of these inns and B&Bs have their own pool. Confirm if bikinis are allowed on the beach. The distance between the inns and beaches are usually short, but visitors should still dress appropriately to Maldive customs.
More indepent-minded travellers and those looking for cultural experience may consider renting rooms in villages. This will require either walking through the village and asking around if you're particularly confident of your social skills, or inquiring in Male whether someone can put you in contact with their friends or relatives on remote island for such an informal homestay. Prices can be as low as 15 euros per night for a clean functional room.
The education system, although having many problems such as poor student literacy rates in English (the medium of instruction for most subjects), is freely available for all Maldivians.
There is one university in Maldives (Maldives National University) which was inaugurated on 15 Feb 2011, the university was previously known as the Maldives College of Higher Education which was established in 1999, as part of a restructuring and rationalization of all government-run post-secondary education in Maldives. Operated under the aegis of the Department of Higher Education and Training, MCHE is the only public degree-granting institution on the island. The college offers a range of degrees, diplomas, and certificates, with particular emphasis on engineering, health science, education, tourism, and management. The average enrolment at MCHE is around 4,000 students in long-term (that is, more than one academic year) programs, and around 2,000 in short-term (shorter than one academic year) courses.
Getting a job in the Maldives can be tricky. It is not the kind of place where you can just turn up and start job hunting. Generally the resorts take on a mix of local and international staff so you need to approach the resort Human Resources departments. There is a good mix of jobs but a lot of the roles are diving based (divemasters, instructors, photographers, etc.)
Most resorts are predominately one or two nationalities so finding the resorts that match your language skills helps. After that experience always helps (especially for diving instructors as the Maldives are well known for their strong currents and half of the time the currents will take you straight out into the Indian Ocean).
Generally if you get a job with a resort then they will get you a work permit and pay for your flight, food and accommodation. They don't really have much choice, it's hardly as if you can pop out to the supermarket and pick up a pizza for dinner.
All foreign workers have to have a series of medical tests before you can start work in the Indira Gandhi Memorial Hospital. This includes a blood sample (lots of tests including HIV as well as x-ray etc.). It is quick and easy but they are very uncommunicative about what they are doing.
There is very little crime in the tourist resorts with their patrons often not venturing wider afield. Generally, Maldivians are honest, helpful and welcoming people although you are unlikely to come into much contact with them in resorts.
There are no drugs anywhere in the resorts but most Maldivians have easy access to drugs. Drug addiction is increasingly common and petty crime has been on the rise. Take the usual precautions such as not leaving money and valuables lying around. Note that every US$50 you spend at a bar or restaurant represents 10 days' wages for cleaners.
Anti-government street rioting has occurred repeatedly in Male in recent years, and activists have sometimes targeted the tourism industry. Avoid getting involved in any political activism or protests.
Homosexual activity between consenting adults is punishable by life imprisonment. Discretion should be exercised by LGBT visitors.
Cases of sexual harassment are not rare in Maldives. Solo female travellers should be vigilant, especially at the bikini beaches.
Broad-based discrimination against non-Muslims is entrenched in the nation's laws. In 2011, a foreign schoolteacher was imprisoned for possession of a Bible and a set of Catholic rosary beads. The country's constitution was amended in 2008 to deny Maldives citizenship to anyone but Sunni Muslims. There is no freedom of worship; alcohol and pork are available only at resorts and a few other places catering to foreign visitors. Non-Muslims are not permitted to marry in the Maldives, are forced to have their children educated in the Muslim tradition and are excluded from public office. Apostasy, blasphemy, and criticism of Islam are illegal; promotion of other religions or possession of non-Muslim religious objects of any kind is illegal. Proselytizing is said to be one of the fastest ways to get deported from the country.
There are no serious problems with diseases in the Maldives. Beware that tap water may not be drinkable at all resorts: enquire locally. The Maldives are malaria-free, but some islands do have mosquitoes and catching dengue fever from them is possible, albeit highly unlikely. For those coming from regions infected by yellow fever, an international certificate of inoculation is required.
Most of the problems come from diving or sun related injuries. Heat stroke always cause problems in the tropics but couple that with divers spending hours at a time on a boat wearing a wetsuit and overheating of one form or another is a real issue. Keeping this in mind, such injuries will be easily avoidable as long as you drink lots of water and get into the shade as much as possible.
Lots of the resorts have their own doctor or nurse and most are within easy reach of the decompression chambers. Male has an efficient and fairly modern hospital but bear in mind that it is a long way to get medically evacuated home from.
There are two mobile operators: Dhiraagu and Ooredoo. Both of them sell local prepaid SIM card with internet connection at competitive rates. The first mentioned of them is the leading local telecom company which has wider coverage while prices are about the same with its competitor. They both have shops right next to the airport arrivals area upon exiting. Also both offer 3G/4G data connections. Also if you plan to sail maybe you can be interested in satellite service offered by Ooredoo.
Most hotels and cafés offer public Wi-Fi but as of 2017 connections are usually really slow, between 56-512 kbps. A local mobile number is needed to purchase time at many Wi-Fi spots around the country.
