Dominica is a mountainous Caribbean island nation with natural hot springs and tropical rainforests. Morne Trois Pitons National Park is home to the volcanically heated, steam-covered Boiling Lake. The park also encompasses sulphur vents, the 65m-tall Trafalgar Falls and narrow Titou Gorge. To the west is Dominica’s capital, Roseau, with colorful timber houses and botanic gardens.
