Diving & Snorkeling
Dive and snorkeling trips operate here only in the dry season, from mid-October until May; most trips head to the islands of Ko Khlum and Ko Wai (a particularly beautiful island), or to Ko Phrao (for wreck dives). Ploy Scuba (tel. 086-155-1331; www.ployscuba.com) is just one of the island's many diving multilingual outfits.
Ko Chang Adventure: Hiking, Kayaking & Elephant Safaris
Several well-marked hiking trails crisscross the island's peaks, but possibly the most enjoyable leads up from Had Klong Phraew to Klong Plu Waterfall, which is most spectacular July through August.
Three operators run elephant treks on Ko Chang, but the best regarded is Ban Kwan Chang, in the north at Ban Klong Son village (tel. 081-919-3995). You can book tours of varying durations (starting at 8am) at most hotels, which can involve an elephant safari, a short performance and painting, and then a chance to feed the animals before a splashy bath.
During the dry season, bands of budding Indiana Joneses can explore the east coast's mangrove forests via the Salak Kok Community Foundation (tel. 084-106-7541). The foundation organizes a two-man kayak for 100B per hour, or a more interesting guided mangrove tour for 200B. It also arranges sunset suppers, on a small boat in Salak Kok bay, for 1,400B per person (minimum of four persons).
More outdoor fun can be had at the Treetop Adventure Park (tel. 084-310-7600), in Bai Lan, where you can teeter along walkways and whiz along ziplines suspended over the jungle. Some operators are also offering Dolphin Tours, but the keen-eyed may be able to spot these delightful creatures without help in October -- they perennially bound alongside the ferries as they cross the short channel.
