Between limestone, deep, coral-lined cracks slope to a sandy bottom. Different species of shellfish and crab make this their watery home. If you look to the right just past the crevasse, you'll find similar terrain, except that this eventually leads to a sheer drop. Check out small caverns and try to see what kind of creatures the wall crevices contain. If you dive at Onna Point at night, the number of sea life increases, with lobsters adding to the underwater ensemble.
Diving is great as well snorkeling or just plain ol beach combing.
Touring around and checking out some of the local happenings is pretty neat here also as it is a resort area. There is also a bike path that follows the coast along the ocean for about 24 kilometers.
