This popular dive and snorkel spot is well known on the island because of the unique bubbles that rise out from the reef, caused by thermal vents escaping from the nearby (5 Miles away) volcano. When you dive / swim in front of bubbles, you can feel their warmth. The reef is a little treacherous accessing as the beach is covered in rocks, and rocks are also all along the shoreline a good 5 to 10 feet out, before the water deepens enough to swim. I hired a guide to get me in and out safely because so many were getting beaten up on the rocks. Worth every penny. Donny turns out to half fish and knows every crevasse of the reef. He stayed with me for an hour and was constantly free diving down pointing out all kinds of things on the reef. So many fish and coral and saw a whole family of turtles. He would dive down to the thermal vents and fill up his snorkel pipe with the warm mineral water, then pour it in my hands for me to rub all over my face and head - said each washing, would erase 10 years! I gained 30 years back! He did for my friends too! One guy wanted a gallon for his bald head! Parts of The Pirates of the Caribbean movie was filmed here. There was a rope bridge scene done here and remnants remain up on the hill, above the cove, of the bridge.
