The first in a chain of islands popular with backpackers and flashpackers for its size and variety and is perhaps the first stop after some interior travel in Thailand. Chaweng beach. Massive seated Buddha blessing the local fisherman and waterfalls are some of the interior delights but there is now a fishing lake for fresh water asian carp and catfish that you can catch !
While Chaweng suffers from perhaps over development it is a great beach and the food at the restaurants there is great. A variety of on the beach accommodations from 500 to 1000+ Baht make it an easy place to find what you want.
Tip : It is no longer as cheap as it used to be to fly to and from Koh Samui and is not served by the budget airline air asia. A reason why many travel to Surat Thani on the mainland close by to save 3000 Baht to fly back to Bangkok.
