Angthong National park
Angthong consists of 42 islands, its name means “Golden Urn” in Thai. The scenery topside is very similar to the Andaman side with many limestone outcrops and formations. The two most popular dive spots in the national park are at Koh Wao and Hin Yippon where you can enter shallow caves and swim throughs. Soft and black corals are plentiful and you may spot banded sea snakes and turtles here. It is also one of the few places where, if you’re lucky, you may see whale sharks. This site is also very good for Discover scuba diving as well as experienced divers, its also a great place for the family to go snorkelling.
