Isolated in the middle of the South Atlantic, 1200 miles from the coast of Africa, and 1800 miles from South America, the ocean surrounding St Helena has a well preserved coral ecosystem and its pristine, unpolluted waters and teeming with marine life. The natural clarity of the water around St Helena is stunning, offering a visibility of up to 30 metres. This makes it the perfect spot to watch an abundance of marine life, including the Island’s endemics – there are a number of species of fish found only in St Helena waters including Devil Rays and Whale Sharks which are a particularly popular attraction for visitors.
