About Hot sulfur
Hot sulfur is a guided reef dive in Dominica’s Soufriere Scotts Head Marine Reserve, where a deep reef sits above sulfur bubbles and warm water that rise from the seabed. The dive is memorable because of the geothermal atmosphere more than the distance swum, so a local boat operator, steady buoyancy, and a conservative profile matter more than speed. It is best for divers who want a short, unusual reef dive with a volcanic feel and clear-water conditions when the sea is calm.
