Oahu (Hawaiian: Oʻahu) is the most populous of the Hawaiian islands, the third largest in size (after the Big Island and Maui, and the cultural, financial, and top tourist destination of the Hawaiian islands. As the home of the city of Honolulu, the state capital, and as home to over 85% of the state's population, Oahu is appropriately nicknamed "The Gathering Place."
Oahu is truly at the heart of Hawaii. The city of Honolulu is busy, and its Waikiki district even more so. Oahu is home to the only real metropolitan area in all the Hawaiian Islands. For some, this has been both a blessing and a curse for the island.
On the plus side, visitors to Oahu and local residents themselves share in all the amenities and conveniences that only a large city such as Honolulu can provide—days spent dashing about, bustling nightlife, great restaurants, exciting cultural events and establishments, good public transportation, and a variety of shopping and lodging options. Combine this with the city and island's extensive beaches, parks, mountains, recreational areas, and quaint towns and this makes one enjoyable metropolitan area. On the minus side, Honolulu is a big city and has all the big city problems that come along with it, such as traffic, high cost of living, and some crime.
Honolulu may not embody the vision that some visitors have of Hawaii after looking at so many postcards: serenity and relaxation. True, one can relax on Oahu just by going to the right destinations on the island, you just need to know where to look. A calming oasis can be found as there are many resorts located outside of Waikiki that offer less crowded surroundings. Natural beauty can be found in the two mountain ranges, the Koolau and Waianae ranges. Some great hikes are just a short drive into the mountains from Waikiki. Secluded white sand beaches, funky beach towns, pounding winter surf on the North Shore. All of which can be found in other parts of Oahu.
So enjoy Honolulu and all it has to offer. But if you don't see the North Shore during the wintertime when monstrous waves pound the shore (think of the opening scene of the 1970s show Hawaii Five-O), then you have really missed something. Brave and experienced surfers attack these waves! If you don't take a drive through miles of pineapple fields, and if you don't take time to visit some of the white sand beaches, mountain trails, and scenery outside of Waikiki, then you really haven't seen all Oahu has to offer.
Two mountain ranges make up the island of Oahu. The Koolau Range (Hawaiian: Koʻolau) runs along the east side of the island and forms the backdrop for Honolulu; the Waianae Range (Hawaiian: Waiʻanae) runs parallel to the Koolau Range along the west side.
The majority of visitors to Oahu stay in Honolulu and its Waikiki district. The rest of the island is less visibly touched by tourism, with only a few B&Bs among the houses and natural sites on the Windward Coast and the North Shore.
The largest city in the Hawaiian Islands, the size of Minneapolis, Minnesota and home to the tourist hotspot of Waikiki.
A mostly suburban mix of bedroom communities for Honolulu and miles of pineapple fields.
The wetter and more lush part of the island, home to many secluded beaches, sleepy villages, and one of the largest Marine Corps bases in the Pacific.
The drier part of the island, with four rural communities and two up-and-coming resort areas.
Home to some of the largest waves on earth in the winter; the ocean and surfing are a way of life here.
Flights from all over the world land at Honolulu International Airport just outside of downtown Honolulu. Free Wiki-Wiki (Hawaiian for "quick") shuttle buses run between the Main Overseas Terminal and Interisland Terminal every 15 minutes. These will eventually be replaced with moving walkways and people movers.
TheBus routes #19 and #20 run between the airport and Waikiki. The fare is $2.50. Exact change is required and space for baggage is limited.
When taking TheBus from the airport to Waikiki, make sure the destination sign reads "Waikiki Beach and Hotels". The westbound #19 bus continues to a military installation (Joint Base Pearl Harbor-Hickam), and Military Police check all passengers for military ID at the gate. Do not get on this bus if you do not have military ID: you will be left at the gates with no way to return to the main highway.
Car rentals are available at the airport and various locations downtown. A car is worth having for visits to the North Shore or if you are staying outside of Honolulu/Waikiki.
The Oahu bus system, officially called TheBus, runs between almost all towns and to most tourist destinations. Fare for TheBus is $2.50; exact change is compulsory and it will get you anywhere on the island TheBus goes.
There is a 4 day TheBus Tourist pass available from most ABC Stores (like a 7/11) for $25. Make sure you 'scratch' it correctly before getting on the first TheBus.
Also available from ABC Stores and other Waikiki-area shops is a very handy guide to TheBus for $2.95.
The tram-style "Free Shopping Shuttles" which pick up around Waikiki beach will take you to the Ala Moana Center. Be aware that this shuttle will first take you to Hilo Hattie's flagship tourist shop west of the center. It's free, but not a direct route so if you're not interested in stopping off at Hilo Hattie's you may prefer to look elsewhere for transport as this option will add at least 30 minutes to your commute.
New rail project
Oahu and the City and County of Honolulu are currently working on a new elevated rail project to transport people more effectively on the island. The project is officially called the Honolulu High-Capacity Transit Corridor and is expected to be completed in phases through 2012 and 2019. Some locals believe that the new rail transit will be named, TheRail, after the currently existing TheBus system. It is expected to connect the southern Leeward Coast (commonly known as the West Side, or West Oahu) with Ala Moana Shopping Center in downtown Honolulu.
The following are some of the more important major highways on Oahu. Both the common name and the state route number are given here. With the exception of H-1, H-2, and H-3 locals refer to most state highways by name, rather than route number.
A common question that mainland visitors ask is why Oahu has Interstate highways when they don't cross state lines (or even county lines for that matter). The answer lies in the full name of the National System of Interstate and Defense Highways. Each of the Interstates had a military base at or close to its terminus, and all of them run close to Joint Base Pearl Harbor Hickam. (In any event, there are a number of Interstates on the mainland that also run entirely in one state.)
- H-1 is an interstate freeway that runs from Kahala in East Honolulu west, through downtown Honolulu, past the airport and out to the western suburb of Kapolei where it joins Farrington Highway. H-1 is the busiest and most heavily used freeway on Oahu.
- H-2 is an interstate freeway that runs from the town of Waipahu through Mililani to the town of Wahiawa in Central Oahu.
- H-3 is an interstate freeway that runs from the suburb of Aiea, through the windward communities of Kaneohe and Kailua, to the gate of Marine Corps Base Hawaii.
- Moanalua Freeway/H-201 is an interstate freeway auxiliary route that serves as an alternative route for H-1. It runs from the Middle Street Merge (H-1, H-201) in the community of Kalihi in West Honolulu to the H-1, H-3, H-201 merge in Aiea. Some freeway signs may still label Moanalua Freeway as Route 78, even though Route 78 has since become H-201 in 2004.
- Nimitz Highway/Ala Moana Boulevard (state route 92) runs from Pearl Harbor to Waikiki; it is the main route from the airport to Waikiki.
- Pali Highway (state route 61) runs from downtown Honolulu to the Windward town of Kailua.
- Likelike Highway (state route 63) runs from the Kalihi district of Honolulu to the Windward town of Kaneohe.
- Kalanianaole Highway (state route 72) starts from the east end of H-1 and runs through the East Honolulu suburbs around Makapuu Point, and through the rural community of Waimanalo, ending in Kailua.
- Kamehameha Highway (state routes 99, 80, and 83) is the main highway on Oahu, starting from Pearl Harbor, going through the leeward communities of Aiea and Pearl City, then through Central Oahu, around the North Shore, and along the Windward coast ending at the town of Kaneohe.
- Farrington Highway (state route 93) is two separate roads: the south side starts where H-1 leaves off in Kapolei and leads to the Leeward coast communities of Nanakuli, Waianae, and Makaha, ending at the south end of Kaena Point State Park. The north side starts from Waialua on the North Shore through the community of Mokuleia to the north end of Kaena Point State Park(the road used to go around the point but the part that actually rounded the point has been closed and replaced with a nature preserve. A trail connects the two portions).
- Fort Weaver Road/Kunia Road (state routes 76, 750) goes from Schofield Barracks near Wahiawa south to Ewa Beach.
No services available.

Oahu has the following beaches:
- Halona Beach Cove - This beach is also nicknamed Eternity beach, receiving the name eternity because of the love scene that takes place on this beach from the movie "From here to Eternity". Most tourists usually go to this spot on the east side of the island just past Hanauma Bay to view the Halona blowhole. The only way to get this beach though is to scale down the somewhat steep cliffs that protect this tiny but very scenic beach.
- Hanauma Bay Nature Preserve - This beach is a Nature Preserve, the Bay is a flooded crater surrounded by several cratered cones and is home to over 250 species of fish. The Bay is a favorite of locals and tourists alike, there is a small fee for entrance and parking. The one drawback is the realitively small parking lot, so consider taking the bus or get there early. Lifeguards are present and skin-diving equipment is available for a fee.
- Sandy Beach Park - Located between Hanauma Bay Nature Preserve Park and Makapuʻu Point along Kalanianaʻole Highway, the beach is regarded as one of the best bodyboarding sites in Hawai’i. Known for steep, hard-breaking waves in Sandy’s shorebreak and rip currents. Many experienced bodysurfers are always in the water, making riding the waves look easy. Visitors unfamiliar with the beach misjudge the dangers and often get into trouble.
- Makapu'u Beach Park - Hawaiian for "bulging eyes", this beach is located just below Makapu'u Point, the easternmost point on O’ahu. One of the most famous bodysurfing beaches in Hawai’i. During the summer the beach is wide and the ocean is usually calm. During the winter high surf erodes the beach, exposing large rocks in the pounding shorebreak, and generates powerful rip currents.
- Kailua Beach Park - Located just below the Kaneohe Bay and directly above Bellows air force station, this beach is famous for its excellent swimming and wind surfing. With nice fine sand - perfect for sunbathing and recreational activities, and a backdrop of tiny offshore islands, this makes for one of Oahu's most beautiful beaches. Recently, the beach has suffered from erosion, removing a significant amount of sand from the shoreline. As a result, the space available on the beach has been severely reduced.
- Lanikai Beach - Located in Lanikai, a neighborhood within Kailua, on the windward coast. This small stretch of thin beach is home to some of the most clear and blue water you will find surrounding Oahu, and with views of the two beautiful offshore islands, known as the Mokuluas or Nā Mokulua, you truly feel engulfed in the tropical setting.
- Bellows Beach Park - Located near Bellows Air Force Station (Bellows Field) in Waimanalo, fronted by a long, wide, sand beach. A shallow sandbar off the beach provide good waves for bodysurfing and bodyboarding.
- Kualoa Regional Park - Located along the Northeast side of the island, this beach is rarely crowded and has a great view of the offshore island, Chinaman's hat, so called this due to its resemblance of the peasants chapeau worn by rural Chinese. With Kualoa mountains in the background you might feel you are in the movie Jurassic park, due to the fact that Kualoa range is where much of the footage took place. Also this area was considered sacred by ancient Hawaiians due to the whalebones that would wash on shore that would be used for valuable tools and jewelry.
- Kahana Bay Beach Park - Located along the Kamehameha Highway adjacent to Ahupua'a O Kahana State Park between Kaʻaʻawa and Punaluʻu. This beach cove is nestled at the very bottom of the Kualoa mountains and is often over looked by people traveling up the coast due to the outlining of pine trees along the beaches edges. With its seclusion, calm waters and plenty of shady spots for those not fond of the too much sun, you can obviously see why this is one of Oahu's best kept secrets.
- Sunset Beach - Located off Hoalua Street and Kamehameha Highway on the North Shore. Named to promote the area’s spectacular sunsets, this white sand beach is one of the longest running beaches on Oahu, stretching 2 mi (3 km) in length and between 200-300 ft (61-91 m) in width at some spots. Home to several internationally renowned surfing contests, including the Triple Crown of Surfing since 1983. A bike path runs from Sunset Beach to Waimea Bay - a great way to spend the day exploring the hidden spots that you cannot see from the main road. Bike rentals available at Paradise Baby Co. (adult and childrens bikes).
- Ehukai Beach Park - Also known as "Reddish tinged water", this also home of the famous Banzai Pipeline. In the winter months this beach features 30-40-ft (9-12 m) waves, when the swells are high, and frequented by many of the worlds best surfers. Part of the triple crown surf tournament, I would stay out of the water in the winter months unless you are familiar with the surf, due to the fierce breaking waves and strong undertow. However in the summer months the calm ocean makes a good spot for swimming and a good sandbar. Always check with a life guard at this beach before entering the water.
- Hale'iwa Beach Park - Located in the Historical town of Hale'iwa fronted by a narrow brown sand beach. While its shallow, rocky ocean bottom does not attract many swimmers, the park is well-used by canoe paddlers as a training and regatta site, by kayakers as an access point to the bay, and by surfers who ride the waves at Pua’ena Point.
- Mokule'ia Beach Park - Mokulēʻia means "isle (of) abundance" in Hawaiian. Located on the northwestern tip of the island, this long white sandy beach is frequented by many of the local Hawaiians for its enticing windsurfing conditions and nice fishing spots.
- Three Tables - This beach located off the Kamehameha Highway, North Shore, between Sharks Cove and Waimea Bay. Part of the Pupukea Beach Marine Sanctuary, this popular dive area is named for three table-like sections of reef that can easily be seen during low tide.
- Waimea Bay Beach - Located along Kamehameha Highway on the North Shore, Waimea means "red water" in Hawaiian. Waimea Bay is one of the most famous big wave surf sites in the world. Waves breaking on the north point of the bay often reach heights of 25 feet, attracting many of the best riders in the international surfing community. During the summer months the wide sand beach at Waimea is a popular swimming and snorkeling site. Part of the Pupukea Marine Life Conservation District.
- Ko'Olina - A resort featuring some of the most beautiful man-made beaches on the island. The four lagoons are named Kolola (whale), Honu (turtle), Nai'a (dolphin), and Ulua (fish). With literally no surf the lagoons are nice to just float around in. Given that the lagoons are about 40+ minutes (rush hour makes it over an hour) from Waikiki these lagoons are generally not crowded on weekdays but the limited parking lots fill up quickly on weekends.
- Pokai Bay Beach Park - Hawaiian for "Night of the Supreme one", this beach is named after the Hawaiian chef Pokai who according to legend brought and planted the first coconut palm tree on the island. This west shore beach is one of the most protected beaches on the island even during the months of rough surf, which makes for nice swimming conditions.
- Ala Moana Beach Park/Magic Island - Known as "The path to the sea", this beach park is famous for its recreational activities. Located just west of the Waikiki beaches and directly across from the Ala Moana mall, this area features a 76-acre park located along the shore, and is often home to many family gatherings and company outings.
- Waikiki at Duke Paoa Kahanamoku Beach Park - also known as: Waikiki, Kahanamoku Beach, Milo Tree, or Fort DeRussy Beach. Kahanamoku Beach lies between the Ala Wai Small Boat Harbor to the west and the Hilton Hawaiian Village’s catamaran pier to the east. A shallow reef protects the beach and provides a popular swimming area for families with children.

Although Oahu is generally not regarded as a premier dive destination, there are many reasons to consider diving here. The islands have fewer types of coral than any other part of the tropical Indo-Pacific, and reef health has been impacted by a variety of human forces, including population increases, shoreline development, land-based sources of pollution, increased sediments in the water, damage by tourists and divers, groundings, poor water quality from runoff and sewage treatment, and over-fishing. But Hawaii has a greater number of endemic tropical marine fishes than any other region except the Red Sea.
At the present time there are three MLCDs (Marine Life Conservation Districts) on Oahu - Hanauma Bay, Waikiki, and Pupukea. The MLCDs are designed to conserve and replenish marine resources. The taking of any type of living material (fishes, eggs, shells, corals, algae, etc.) and non-living habitat material (sand, rocks, coral skeletons, etc.) is generally restricted, if it is permitted at all.
Reef Dive Sites:
- Hanauma Bay - Water depths in the inner bay range to about 30 feet, and visibility is generally good. The outer bay is recommended only for experienced divers. Depths range up to about 70 feet, and there is a large finger coral reef on the left side.
- Pupukea - includes three dive sites on Oahu's north shore - Shark's Cove, Firehouse, and Three Tables - with depths ranging from 20-45'. Many ledges, arches, lava tubes and other features. From about May through October the water is generally calm, but surges are possible. During winter months current and wave conditions become extremely dangerous in all areas.
- Kahe Point Beach Park (also known as Electric Beach) An adjacent electric generating facility outflows clean warm water through two giant cooling pipes offshore. Easy beach entry when the surf is low, with depths ranging from 5-35'.
- Trench Dive - (also known as Haleiwa Ali'l Beach Park) Park your vehicle in Western parking Lot of the park. Entry is easy, walk to left side of Main building. Water depth is only 1-2' for about 100m then starts to drop off. Wall starts at 10' and drops to about 90' Trench was originally built to hide submarines. Southern wall is most dramatic.
Wreck dive sites:
- The Seaplane Wreck - a twin engine Beechcraft airplane off the west coast with a maximum depth of 100'/30m. Sunk in 1986 as an artificial reef project.
- Corsair Airplane Wreck - a deep dive with a maximum depth of 107'/32m. A mostly-intact wreck submerged since 1945 when the pilot ditched it after engine problems during an exercise.
- Mahi Wreck - a former minesweeper/cable layer sunk off the west coast in 95'/29m of water, with the deck between 60-80'/18-24m. Shortly after being sunk as an artificial reef project in 1982, Hurricane Iwa repositioned the ship 180 degrees.

See the Eat section in Hawaii for more details on island food in general. Honolulu and Waikiki in particular offer a vast array of dining options for tourists. On the North Shore be on the lookout for shrimp trucks which patrol the highways and offer plate lunches for under $10.
The local farmers markets on Oahu are also a great place to consider for fresh and local food. These markets are a reflection of life in Hawaii, where the community revolves around good, local food.
Waikiki offers numerous bars, and Kuhio Avenue in Honolulu is home to most of that city's bars and nightclubs.
Within Honolulu, and particularly in Waikiki there are a vast number of lodging options. Outside of these areas there are very few hotels on the island, but there are vacation rentals. Due to zoning regulations some vacation rentals only accept stays of 1 month or longer.
Some areas, including parts of Downtown/Chinatown, Pearl City, Waianae, Nanakuli, Waipahu, and Kalihi, are not very safe after dark. Officers from the Honolulu Police Department are extremely helpful to visitors and will steer you away from potential problems.
Some beaches are unsafe due to surf conditions or currents. Always check the Local Oahu Beach Conditions in advance to know the dangers. Check with the lifeguards and look for flags (Yellow=Caution; Red=Dangerous; Black=Extremely Dangerous). Underwater rocks and coral can be very shallow in some locations even with large waves, so know before you go. Some beaches (like Sandy's Beach) have very large very dangerous shorebreak at times. It is good to know general Beach Safety to understand the risks.
Take care when hiking on trails. Several trails are hazardous, especially after large amounts of rain, go with someone who is familiar with the area. It is very easy to get to dangerous locations that are not marked by signs or railing. When hiking near on rock shelves beside the ocean, dangerous areas are not blocked off. Understand the conditions of the oceans and take note how high up the water has splashed due to wave action. It is not uncommon to have areas that are safe and fun to explore until surf conditions change making them dangerous or deadly. If you fall into the water in high surf near rock walls, SWIM AWAY from the rocks and shore, DO NOT PANIC, call for help and swim parallel to the shore to location of little wave action or toward sandy areas.
Remember that as much as you need to keep yourself safe, you need to keep Hawai'i safe as well. Please practice the Leave No Trace principles to make sure everyone can enjoy the islands. It's not only illegal to do things like feed or hassle wildlife, take rocks, sand or plants, but it's also immoral and detrimental to the Hawaiian Islands. They are the most isolated land mass on the globe and have many species and landscapes that are struggling to survive under the pressures of tourism. Respect the 'aina the best you can. Do not cut trails, litter, or desecrate natural or man made sites.
