Just 8 kilometers east of Roseau, the capital of Dominica, it’s a three-hour walk from Laudat to Boiling Lake. Three hours of humid forest, desolate valley, soil-heated rocks and sulfurous fumes. At the end of the path, a 63-metre-wide pool. Inside, the water bubbles almost continuously, with temperatures measured up to 91.6°C at the edges. It’s the second largest bubbling lake in the world.
A rare phenomenon in a UNESCO park
The world’s first is Frying Pan Lake in New Zealand’s Waimangu Valley. But the Dominican Boiling Lake is in a class of its own. Firstly, because it can only be reached on foot, after a demanding hike. Secondly, because it is part of a national park that has been a UNESCO World Heritage Site since 1997: Morne Trois Pitons National Park. This makes it one of the most singular geothermal phenomena protected in a world-renowned natural site.
A flooded, rain-fed fumarole
Geologically, Boiling Lake is what scientists call a flooded fumarole – an opening in the Earth’s crust that lets out volcanic steam and gases. The heat comes directly from the volcanic activity below. The lake is fed by rainfall, nearby slopes and small streams. Its exact depth is difficult to determine: the first measurements in 1875 indicated a depth of over 59 metres, but recent data vary according to sources and the state of the lake.
An unstable lake since the 19th century
The lake was first observed in 1875 by Edmund Watt and Dr Henry Alford Nicholls, two Englishmen working in the colony, accompanied by their guides. Since then, lake levels and temperatures have fluctuated dramatically. In 1880, a phreatic eruption in the Valley of Desolation had a profound effect on the area. There have also been several episodes of significant drops in water levels, notably in 1988 and between December 2004 and April 2005. The UWI Seismic Research Centre, based in Trinidad, monitors the lake’s activity as part of its volcanic monitoring program in Dominica.
Dominica, an island of visible geology
Dominica’s absolute uniqueness lies in a particular alignment. The island – around 750 km², with a population of almost 70,000 – boasts a geological and ecological density that is rare in the Caribbean: several potentially active volcanic centers, 365 rivers according to the country’s tourism communication, a tropical forest that is still very much present, and the last pre-Columbian Kalinago population in the eastern Caribbean. Boiling Lake is one of the jewels in the crown.
A human memory around a natural site
For the Kalinago people, Dominica’s land, landscapes and natural spaces bear an ancient memory. During the colonial period, the island’s mountains and forests also served as refuges for Maroon populations fleeing the plantations. This dual indigenous and African memory gives the territory a historical depth that few geological curiosities can claim. Boiling Lake is not just a natural curiosity. It’s part of an island of memory.
A demanding hike, not a simple excursion
The hike to the lake is a demanding one. The official trail starts from Ti Tou Gorge, near the village of Laudat, and takes about three hours to get there, then the same to get back. The route passes through the Valley of Desolation, where steam comes out everywhere, sulfur deposits stain the rocks, you can sometimes cook an egg in the cracks in the ground, and the smell of sulfur marks the air. The authorities strongly recommend that you set off with a certified guide, don’t start hiking after 10 a.m., wear suitable footwear and check the weather forecast before setting off.
What Boiling Lake has to say about Caribbean tourism
At a time when the Caribbean is seeking to position itself as a destination for experiential tourism, Dominica offers a clear answer. No all-inclusive beaches. No over-the-top resorts. A hike of several hours to see a lake boil. And UNESCO status to protect it all. Boiling Lake tells the story of another Caribbean: a Caribbean of volcanoes, forests, rivers, trails, memories and landscapes that don’t come without effort. Perhaps that’s where its strength lies. Dominica doesn’t just sell scenery. It’s a reminder that Caribbean nature can still command respect.
Boiling Lake is located in Dominica’s Morne Trois Pitons National Park, a UNESCO World Heritage Site since 1997. The hike usually starts from the Laudat area, near Ti Tou Gorge. It takes around three hours’ walk each way to reach this bubbling lake, set in a volcanically active environment of rainforest, hot springs, sulphur deposits and the Valley of Desolation.
Boiling Lake is famous for being the second largest bubbling lake in the world, after New Zealand’s Frying Pan Lake. Its basin is around 63 metres wide and its water reaches temperatures close to 92°C at the edges. This rare natural phenomenon provides an insight into the volcanic power of Dominica, an island where geology remains visible through fumaroles, hot springs and volcanic landforms.
We strongly recommend that you visit Boiling Lake with a certified guide. The hike is long, physical and sometimes challenging, especially due to the heat, humidity, slippery rocks, sulfurous fumes and rapid weather changes. The trail passes through geothermally active areas, notably the Valley of Desolation. A guide helps to make the route safe, explain the site and avoid mistakes in an impressive but potentially dangerous natural area.
