View of Lake

The Boiling Lake is situated in the Morne Trois Pitons National Park - Dominica's World Heritage site. It is a flooded fumarole 6.5 miles (10.5 km) east of Roseau, Dominica. It is filled with bubbling greyish-blue water that is usually enveloped in a cloud of vapour. The lake is approximately 200 ft (60 m) across.

The first recorded sighting of the lake was in 1870 by Mr. Watt and Dr. Nicholls, two Englishmen working in Dominica at that time. In 1875, Mr. H. Prestoe, a government botanist, and Dr. Nicholls were commissioned to investigate this natural phenomenon. They measured the water temperature and found it to range from 180 to 197 degrees Fahrenheit (82 to 91.5 degrees Celsius) along the edges, but could not measure the temperature at the centre where the lake is actively boiling. They recorded the depth to be greater than 195 ft (59 m).

Periodically, there have been fluctuations in the level and activity of the lake, most recently from December 2004 to March 2005. It was all but empty (06/2006). The lake is currently full and boiling vigorously (late December 2006).

There is no road leading to the lake. In order to get there, people have to hike about 13 km, total of three hours one way.
