Southern reefs, Antilles islands
This reef encircles the whole island by a narrow band of coral reef. The island has 54km of coastline, which means there is a great deal of reef. There are thought to be around 80 good diving sites, with 6 considered amongst the best in the world.
On the southern side of the island, the sea floor falls away just 100m from the shore, which means that gentle slopes covered in coral, give way to incredible coral walls. Huge numbers of fish are all around, as well as bigger creatures off the coast.
