About Dominica

Dominica is a volcanic island in the eastern Caribbean, steep and heavily forested, with rivers, hot springs and mountains rather than long sandy coasts. Morne Trois Pitons National Park holds the Boiling Lake and waterfalls, dive sites lie offshore, and the Kalinago Territory preserves indigenous culture. The drier months from February to May suit hiking and diving, while the wetter season is greener but storm-prone.
