4. Dominica

If you want to see a variety of landscapes in one place, go to Dominica! Volcanoes, rivers, waterfalls, deep gorges and the world’s second largest hot spring! What more do you want? Dominica is about half-tropical forest while one-third of it is national parkland. Tourism hasn’t been promoted here as well as on other Caribbean islands but if you manage the trip and don’t mind the lack of major tourist facilities, Dominica is a great place for sun seekers and soul searchers and definitely one of the top island destinations for 2018!
