8Richelieu RockLocation : South East of Koh Surin The Richelieu Rock snorkeling season is November to April. Whale shark sightings are not guaranteed, you need luck. The best months are February to April. When they come they hang around in shallow water often allowing snorkelers to swim with them for hours. Richelieu Rock is full of fish. Another highlight for snorkelers is big swirling schools of chevron barracuda.
Richelieu Rock is a pinnacle that breaks the surface in the middle of the ocean. There is no other land around which is why so much fish life is attracted to the area. The water clarity is sometimes very clear but at other times it can be a little green, the limestone rock makes the water very nutrient rich, again, attracting the pelagic fish to feed. Currents can be strong at times. So this open ocean snorkeling is really only suitable for those comfortable in the water.

left to divers with a bit of experience.
