Koh Phangan is full of outdoor adventure and most of it can be done on a few Baht. Rich coral reefs run along the north-west coast of the island, supporting a vibrant underwater world making it an excellent place to snorkel and one of the cheapest and least-crowded places to dive in Thailand. There are fishing trips, around the island boat trips and loads of watersports on offer including kayaks, catamarans and fishing.
The island has acres of rich undisturbed tropical rainforest and a wild jungle interior. There are overnight mountain treks to the top of Khao Ra and coastline walks making it possible to beach hop round the whole island. You can find some amazing viewpoints from the mountains and several waterfalls, with some enticing enough to bring Thai Royal visitors.
There are also several Thai boxing schools, gyms and Thai boxing stadiums in both Thongsala and Haad Rin. Koh Phangan is great for cycling around and if you are an experienced motorcyclist it offers some fun rides. There are loads of temples to visit, spa and meditation retreats and it’s also a pretty good place to do nothing at all!
