Frenchman's Bay is the more popular cove in Treasure Beach, among tourists and locals alike. This beach is great for body boarding. I did not see any place to rent the boards, though. You may have to bring one from home!
The area is also famous for the marine turtles. They come here every year to lay eggs. Although it is an endangered species, some local fisherman still kill them to sell their meat and shells. Do not ever buy a souvenir made of turtle shell!
