Ton Sai and Railay are Thailand’s biggest rock–climbing centres, attracting thousands of experienced and novice climbers every year to the peninsula’s seven hundred bolted routes, which range in difficulty from 5a to 8c (see wrailay.com for a full rundown). Of the many climbing schools that rent out equipment and lead guided climbs, the most established include King Climbers at Ya Ya Resort on East Railay and Basecamp Tonsai on Ton Sai. A typical half-day introduction costs B1000, a full day B1800, while B6000 will get you a three-day course, learning all rope skills; equipment can be rented for about B1300 per day for two people. If you don’t need instruction, the locally published and regularly updated guidebooks, Basecamp Tonsai’s Rock Climbing in Thailand and Laos and King Climbers’ Thailand Route Guide Book, will give you all the route information you need. Unaided over-water climbing on cliffs and outcrops out at sea, known as deep-water soloing, with no ropes, bolts or partner, is also becoming a big thing around here and can be arranged through most climbing schools for about B1000.
Kayaking around this area is also very rewarding – you can get to Ao Nang in less than an hour; kayaks cost B200 per hour to rent, for example on the beach in front of Flame Tree restaurant on West Railay. There are plenty of other activities in the Krabi area that you could hook up with from Laem Phra Nang.
