Tour agents on every beach or at your accommodation should be able to sell you tickets for most of the activities described below. There are spas at Ao Bai Lan and Ao Salak Kok; you can also snorkel and dive in the archipelago.
Ko Chang or “Elephant Island” is named for its hilly profile rather than its indigenous pachyderms, but there are several elephant camps on the island that have brought in their own lumbering forest dwellers so that tourists can ride and help bathe them.
Ban Kwan Chang (Khlong Son) Elephant Camp
East of Khlong Son village (not to be confused with Baan Chang Thai in Khlong Phrao). Based in a quiet, forested area in the north of the island, this is the camp with the best reputation. It was set up by the man behind the Asian Elephant Foundation and is staffed by Suay mahouts and their elephants from Ban Ta Klang village in northeast Thailand, which has for centuries been a centre for working elephants. In the morning, visitors can either do a 40min elephant ride through adjacent plantations or extend the ride to an hour and bathe and feed the animals as well. Return transport from your accommodation is included. You could extend your trip to this part of the island by making the easy 300m walk to tiny Nang Yom falls, 500m beyond the camp, though Khlong Phlu falls in Khlong Phrao are more satisfying.
Kayak Chang is a well-organized, safety-conscious, British-run company offering half- and full-day local trips and expeditions around the archipelago of up to 7 days, as well as kayaking lessons and rental. Return transport from your accommodation is included.
Baan Zen offers private, 90min yoga classes and short courses, as well as reiki courses.
The amiable chef who runs the recommended KaTi restaurant teaches well-regarded cooking classes (Mon–Sat; B1200, including recipe book and transfers as far as White Sand Beach and Hat Kai Bae).
