Volcanic in origin, mountainous Dominica is almost totally covered by rainforest.
Across the island, north to south and east to west, volcanic slopes and gorges dominate the landscape. The highest peak is Morne Diablatins, at 1,447 m, (4,747 ft).
Nine of the Caribbean's sixteen active volcanoes are located on the island of Dominica. One of these is Morne aux Diables, an isolated cone that forms a peninsula at the extreme northern end of the island; it is 848 m, (2,826 ft) in height.
Further south, Morne Trois Pitons National Park is home to three volcanic peaks. The park's "Valley of Desolation" is an area of boiling mud ponds and small geysers. Located there, the Boiling Lake is the world's second-largest hot spring.
According to historical records, Dominica is among the Earth's most rain-drenched lands, and that water runoff forms hundreds of streams, dozens of rivers and a handful of small crater lakes.
