Dominica

From Wikipedia: Dominica is a Caribbean island country between the Caribbean Sea and the North Atlantic Ocean, about one-half of the way from Puerto Rico to Trinidad and Tobago. It is often known as "The Nature Island of the Caribbean" due to its spectacular, lush, and varied flora and fauna, which are protected by an extensive natural park system. The most mountainous island of the Lesser Antilles, its volcanic peaks are cones of lava craters and include Boiling Lake, the second-largest thermally active lake in the world.
