Food and Drinks

Due to the environmental protection, the plastic bottles and snacks are prohibited on the island of Koh Nang Yuan, so you need to leave water bottles in the boat and you are also dependent on the Nang Yuan Resort for food and drinks. Prices here are a little higher than on Koh Tao.


Like other islands in the Gulf of Thailand, Koh Nang Yuan has a humid tropical climate. Koh Nang Yuan is a relatively busy island throughout the year. However, as the destination is ideal for snorkeling and scuba diving, it is best to go there during the peak tourist season which is between November and March. If you are a fan of swimming and sunbathing, plan your visit during the cool season, between December and March, with the temperatures being more enjoyable in this season.


Consider arriving on the island as soon as it opens at 10:00 for you to be among the first to discover the island.

During the tourist season, it is likely that Koh Nang Yuan will be literally taken by tourists at such a level that it may not be worth visiting. You might be better enjoying your time at many other great beaches on Koh Tao and admiring the views from the magnificent Koh Tao viewpoints.
