Overview
The number 1 dive site in Thailand and was once a top ten dive site in the world. Richelieu Rock is a horseshoe shape rock that sits in the middle of nowhere. Only the top of the rock is exposed during low tide. Beautiful purple and yellow soft corals wrap around the main rock with large Gorgonian corals at its base.
This special rock provides refuge and has an abundance of marine life. Small critters such as tiger tail seahorses and harlequin shrimps to pelagics such as whale sharks and mantas can be found here. It is a photographer’s haven.
Due to its popularity, there are always many boats on this small rock and underwater can get crowded. As such, we always take an effort to stagger our dive timing so that we can avoid crowding as much as possible.
