Pitons, St Lucia These two volcanic mountains are one of the most recognizable - not to mention beautiful features on this Caribbean island. Enjoy the Pitons from the pristine white sand beach at Sugar Beach, A Viceroy Resort. Coral reefs cover almost 60% of the site's marine area. A survey has revealed 168 species of finfish, 60 species of cnidaria, including corals, eight mollusks, 14 sponges, 11 echinoderms, 15 arthropods, and eight annelid worms. The dominant terrestrial vegetation is tropical moist forest grading to subtropical wet forest, with small areas of dry forest and wet elfin woodland on the summits. At least 148 plant species have been recorded on Gros Piton, 97 on Petit Piton, and the intervening ridge, among them eight rare tree species. The Gros Piton is home to some 27 bird species (five of them endemic), three indigenous rodents, one opossum, three bats, eight reptiles, and three amphibians.
