Boiling Lake shared by @afar says: ""In the heart of Morne Trois Pitons National Park bubbles this deep, flooded fumarole—the second-largest of its kind in the world. The hike to this dramatic, blue-grey cauldron traverses steep, rain-forested river valleys and skirts around mudpots veiled in steam. The 8.1-mile roundtrip is best navigated with a local guide. Heed trail closures and never swim in the lake. The temperature occasionally drops, but scalding water and harmful gases could erupt at any time with no warning."" on Postcard
