Thailand’s most famous dive site – the crown jewel of Andaman Sea diving!

Richelieu Rock is often ranked among the world’s top 10 sites, and as guests of King Andaman, you can visit it multiple times a week!

Discovered by Jacques Cousteau, this massive pinnacle in the middle of the Andaman Sea offers unmatched marine biodiversity. You can see anything from tiny seahorses and nudibranchs to majestic whale sharks, and everything in between. 

Due to strong currents and open-sea conditions, Richelieu Rock is best explored with an experienced guide from King Andaman. 

We offer 8 dives a week to this legendary site, with day trips from Khao Lak every Monday, Wednesday, Thursday, Friday and Saturday. Some days, we dive the site twice, since there’s so much to see!
