Very interesting and tiring classes. Trainers explain things well and it feels soooo good to excersise this way during a holiday. Muay thai is very popular in Thailand, especially in tourist areas so it's hard to find a good place to learn. Island Muay Thai is probably one of the best ones.
The most popular place in Ko Samui... No temple is as often visited as the Monk. There are waves of tourists, most of them around noon. Nice place overall.
