Ton Sai beach - this is how rocky it is at low tide
Ton Sai beach at high tide

Ton Sai is a beach in Krabi Province, Thailand, offering a combination of inexpensive accommodation and great rock climbing routes that make it popular with both backpackers and climbers alike. Compared to neighbouring Rai Leh and Ao Nang it's relatively rough around on the edges; in particular, the beach gets unsuitable for swimming and becomes quite rocky as the tide goes out. But this only happens for about ten days a month. The rest of the time the beach is suitable for swimming.



Current (2023) Tonsai is separated into two parts. Most of the beach front is used by a site where a large luxury ressort was planned, but never actually built. Only a small part is now used by the pricey Tinidee Hideaway Tonsai Beach. Still, the whole area is surrounded by a concrete wall. Next to it is the Tonsay Bay Resort with two restaurants, some shops and a beach bar. All the resorts which were on the beach front until 2014 were moved up the hill behind the wall. There is one main road starting on the north-western beach going there. However, the path going through the Tonsay Bay Resort is connected to the upper road as well by a security gate, which is almost always open.

If you want to listen to the constant buzzing of long tail boats racing between Aonang Beach, Railay Beach and Tonsai Beach this is the place for you.

Get in


There's no easy overland access to Ton Sai, so all visitors arrive by boat. There is however a difficult trek that will take 1.5 hours from Ao Nang, but its not recommended when you are carrying luggage, and people using this route are regularly attacked by gangs of wild monkeys. There is a half-hour trail from east Rai Leh, also not recommended when carrying luggage, but without gangs of wild monkeys to worry about. At low tide, there is a somewhat difficult scramble between the north end of West Rail Leh Beach through to Ton Sai's easternmost stretch of beach. Rai Leh is a five minute longtail ride, necessary at high tide, while longtails from Ao Nang to Rai Leh will also stop at Ton Sai. Boats between Ton Sai and Rai Leh generally don't run at night.

If you're arriving at Krabi bus station you will need to get a songthaew to Ao Nang Beach. The daytime price is 60 baht. From Ao Nang, share or charter a boat to Ton Sai. Boats run frequently from Ao Nang Beach to Ton Sai. But only when enough people have gathered and the boat is full with 10-12 persons. In high season it takes around 20 minutes to fill a boat depending on the time of the day. In low season it usually takes longer. Tickets cost 100 baht at the ticket kiosk at the east end of Ao Nang Beach, where Ao Nang Rd first meets the beach; at the west end of Ao Nang Beach; or at the Wan Sai Restaurant on Nopparat Thara Beach (east end). The price almost doubles after 18:00.

Alternatively, hire a boat and make a deal with the boatman. Expect to pay the price of 10 tickets if you want the boat all by yourself.

The boat ride from Ao Nang Beach to Ton Sai takes 10 minutes and is very scenic.

There are three ways to move between Rai Leh and Ton Sai on foot:

1) At low tide you can walk around the rocky outcrop which separates Ton Sai from Rai Leh (20 min).

2) At high tide, go to the south end of Ton Sai Beach, walk the obvious path at the end of the beach, through the forest, up and over the rocky outcrop. You'll pop out on the north side of Rai Leh West (20 min).

3) The least-used option is a longer trail through the jungle. Walk away from the Ton Sai Beach along the road where all the bungalows and resorts are. When you get to Wee's Climbing School turn (east) and continue on the road up hill. Eventually you'll pass all the bungalows. Continue on the path and you will eventually pop out on Rai Leh East near the Diamond Cave area (50 min). Although longer, this trail is smoother and easier to walk than the shorter one.

None of these options is possible at night without a flashlight/torch, and the jungle paths can be slippery and treacherous after the rain.

Alternatively hire a kayak and sail around (10 min).

Get around


The only way to get around Ton Sai is on foot. The beach and the main road act as the primary thoroughfares for the area. It may take five minutes or less to cover the entire area. During heavy rains, the dirt road becomes muddy and treacherous.


  • Lagoon (On the way to Phra Nang Beach, a path off to the left of the main track leads steeply up to a landlocked lagoon). Another sight worth visiting. Takes some scrambling to get there, but surrounded by beautiful cliffs and perfect for a dip. Only worth visiting when the tide is high. The pool is sea water and empties out at low tide.
  • Lookout Cave (At the far end of Phra Nang Beach (near Escher Wall), next to Freedom Bar, there is a bamboo ladder that climbs to a lookout point of the bay). Beautiful viewpoint of Ton Sai and Rai Leh west. It is an easy climb up 4 bamboo ladders, but take a torch as it's pitch black in the cave. Breathtaking views that are definitely worth the climb.
  • Phra Nang Shrine (On Phra Nang Beach, which is either a 30 min walk or a 20 min kayak float). Ton Sai is more of an "Do" place than a "See" place. But this is worth visiting. Thai women come here in the hope of increasing their fertility, and the shrine is studded with wooden phalluses. Quite a sight!


  • Playing with fire -- Ton Sai could well be the world centre for fire tricks: light something on fire, twirl it in the air, that's the basic idea. Many climbers can be found on the beach on their off days practising on the beach.
  • Share or charter a boat to nearby islands. Chicken Island is good for snorkelling.
  • Rent kayaks from one of the bungalow operations along the beach and paddle around to Rai Leh or the beautiful Phra Nang Beach.

Rock climbing


The primary draw for visitors, with Ton Sai offering as many routes as Rai Leh, and hosting a number of climbing schools and guide companies.

  • 1 Basecamp Tonsai (Wee's Rock Climbing School). Professional variety of climbing courses. Course prices range from 800 baht for intro courses to 9,000 baht for five day advanced courses. Also the pioneer of Deep Water soloing trips. Their gear shop has the best selection plus they publish the only complete climbing guidebook for the area. Helpful with info on Ton Sai, get a free map.
  • The Rock Shop. The first climbing shop on Ton Sai Beach is a locally-owned and operated climbing shop that provides courses, gear rental, private guides, and guide services. Courses are all-inclusive. Guides are experienced and professional, competing for the Thai National Team. The Rock Shop also produces a climbing guide book, The Pocket Guide, Thailand Sport Climbing available at several shops in Ton Sai, Rai Leh, and Ao Tong for 800 baht. 800 baht for a half day; 5,000 baht for a 3-day course.
  • If you want to climb independently, it's easy to either rent gear from one of the shops, or bring your own. Shops usually give you a package consisting of a guidebook, 14 quickdraws, a 60 m rope, 2 harnesses, 2 chalk bags and 2 pairs of shoes. This usually costs around 800 baht. Its also very easy to meet people if you're looking for a partner, so don't be afraid to just turn up alone but do be careful about who you climb with.
  • Almost all the routes are sport climbs on limestone rock, and are usually well-protected. Because of the proximity of the sea, the bolts tend to rust, so its worth sticking to new or rebolted routes. There are some climbs that are entirely protected by slings and sometimes these are worn through, so bring some extra slings or buy some. You can also buy an excellent guidebook for the whole of Thailand at any of the climbing shops. It has dates and safety ratings for each climb, which is very useful. Beware of local copies with inaccurate info.
  • The climbing is often athletic and overhanging. The rock quality varies depending on the crag, but its usually excellent and the rock formations are very impressive, lots of stalactites. There are some fantastic multi pitches, and you are rewarded with brilliant views from the top. Some of these can be climbed with one 60 m rope, some of them need two. Some of the hardest climbs are concentrated along the beach, which also makes a great bouldering spot because the sand is soft to fall on. There is also a good bouldering cave that stays nice and dry if it rains.
  • The best time to climb is probably during the winter months when its cooler, but it can get crowded, especially at Christmas. The rest of the year its either very hot or raining, and many places shut down in low season. However there are often windows of beautiful weather during the monsoon and the rock usually drys quickly.

Scuba diving




There are very few shops in Ton Sai, and they are pricey (by Thai standards) as everything is brought in by boat. It's probably best to bring everything with you or make a trip to Krabi, which is a much larger town with better choice. However there are a few mini-marts selling cold drinks, snacks, phone credits, and some tacky clothes, similar to the ones at Rai Leh.



There are several restaurants and bars on the beach and most bungalow operators have restaurants as well. Many do not have electricity during the day, meaning that unless they are careful with food storage you'll end up with a nasty case of food poisoning. Normally there is electricity from 18:00-06:00 during low- and mid-season. During high-season there is electricity for most of the businesses.

The street vendors make fantastic authentic Thai food. Try the mango with sticky rice or som tam (papaya salad). Cheap too!!

  • 1 Mamas Chicken Kitchen. Highly recommended. Will do "Thai style" if you ask them. Sells fresh banana bread for 70 baht per loaf.
  • Capote's Pyramid. (on the upper main road). Mexican dishes with a Thai twist, BBQ on weekends and burgers with buns from a bakery.
  • Sao Legacy (on the west side of the beach, a few meters up the concrete road from the longtail stop). Best prices with the biggest plates. Expect a monster and delicious pad Thai, lad naa, or veggie burger for 100 baht, or a huge bowl of fruit with homemade yoghurt and granola for breakfast for 60 baht.



There are several bars on the beach, several of which (oddly enough) feature non-stop reggae music. You can even chill out with a "special" coffee or tea. A popular climber's hang out is Ton Sai Roof, at the east end of the beach, where the routes begin at the foot of Freedom Bar, another hot spot with glorious views of both the rock and the whole bay.

Also be sure to check out Small World Bar, right in the middle of the loop, where there is amazing nightly fire and slackline entertainment and a super relaxed atmosphere with great staff.



All accommodation other than the two modern resorts is set off of the beach and tends to be of the bamboo bungalow variety, and a little more rustic and certainly more affordable than at Rai Leh. Rubbish piles and noisy generators are common nuisances, but as Ton Sai has no mains electricity it is a necessary nuisance.

  • Country Side Resort (Set back behind the beach (follow the path up the hill from the Internet cafe, and take the right-hand fork by Wee's Climbing School. Follow the signs.). Set of 10 bungalows are comfortable and have views. During low-season it is the best deal on Ton Sai. Air-con rooms are also available, but expensive and unnecessary because there is no electricity in the day. 150+ baht.
  • 1 Chill Out Bar & Bungalow (half way between Paasook Resort and Basecamp Tonsai). offers restaurants, accommodation, laundry, free WiFi, a cozy bar and climbing courses. 700 Baht for a double.
