About
The world's second-largest hot spring, this mystical lake sits in a volcanic crater surrounded by dense rainforest in Morne Trois Pitons World Heritage site. The challenging 6-hour round-trip hike through the Valley of Desolation rewards adventurers with the extraordinary sight of a 200-foot-wide lake that literally boils from geothermal activity below. Steam rises dramatically from the grayish-blue waters, creating an otherworldly atmosphere that epitomizes Dominica's volcanic power.
