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.

The Valley of Desolation

A group of friends and I backpacked around the island of Dominica, located in the Lesser Antilles, for two weeks. We hiked the national Waitukubuli trail, camped in the rainforest, and hiked one of the most treacherous trails I’ve ever seen. We even visited the Valley of Desolation, a valley of sulphur rivers, bubbling mud, and eery steam rising from the world’s second largest hot spring source: the Boiling Lake. The hike is only viable when guided by a local, as the trail takes you down steep river beds, rock scrambling around boiling pools of mud, and a dangerous descent down from a forest of clouds. Easily the most incredible hike I’ve ever been on, but not for the faint of heart.
