On every trip I have made to the “Nature Island” of Dominica in the Caribbean I have gone snorkelling at the remarkable Champagne Reef. Hot water and air bubbles up from the sea bed created by volcanic action deep below the surface. In my video you will see them and also the divers that go down to collect the water in their snorkel pipes to show guests just how warm the water is. I made this video while on an excursion off P&O Cruises Britannia ship.
