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.

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.
