About Hot Springs / Underwater Volcano
Hot Springs / Underwater Volcano is a guided boat dive in Pria Laot Bay where warm bubbles rise from a sandy vent field and the seabed cracks change shape over time. The attraction is the volcanic atmosphere more than the terrain, so a slow descent, steady buoyancy, and a local operator matter more than covering distance. It suits divers who want a short, unusual outing with a sulfur hint at the surface and a memorable geothermal backdrop.
