Koh Nang Yuan - Gulf of Thailand

Koh Nang Yuan, just a stone's throw from Koh Tao, is a good spot for a relaxed dive. The main draw for us is the collection of smaller sites around the island, like Green Rock with its interesting boulder formations and swim-throughs that start shallow and drop to around 30 metres. You'll find plenty of reef fish flitting about, especially in the shallower sections. It's a busy place, popular with snorkelers too, but for easy diving and an afternoon exploring some gentle coral and sandy patches, it fits the bill nicely. This area is ideal for newer divers or those looking for a laid-back afternoon underwater without strong currents.
