Snorkeling in Saint Martin can be very fun. Depending on the conditions, there are snorkeling opportunities at many of the beaches as well as Pinel Island (Illet Pinel). Octopus Diving takes snorkelers to less accessible sites by boat which feature more opportunities to see a variety of wildlife.

Creole Rock, for example is an excellent snorkeling site because the waters surrounding the rock go from zero to thirty feet, so mixed groups can enjoy both diving and snorkeling at the same time. Turtle Reef is also a terrific site for snorkeling in St. Martin and snorkelers typically see sea turtles at this site.
