Treat yourself to the relaxing and therapeutic powers of Dominica's mineral waters while surrounded by the island's lush tropical vegetation. Deep in the rainforest, swim in a paradisiacal setting in Titou Gorge, whose dramatic tunnel shape was created by ancient lava flows shaped over the millennia by a waterfall. The village of Wotten Waven is home to steaming sulphur springs that fill natural hot pools where you can enjoy a restorative 30-minute soak.
