Covering nearly two thirds of Basse-Terre island, Guadeloupe National Park is an astounding 54,000 acres of lush rain forest, plus offshore mangrove and coral reefs. Some of the island’s best-known sights are inside the park, including active La Grande Soufrière volcano at its center, 4,800 feet above sea level. The park also contains famous waterfalls like Carbet Falls and the Cascade aux Ecrevisses, and Les Bains Jaunes thermal pool is a refreshing swim after conquering one the park's many hiking trails. Nature lovers will swoon over the 800-plus species of flora and fauna here, ranging from orchids to bats to the endangered agouti (a type of small rodent). You can explore Guadeloupe National Park on your own or go with an outfitter like Vert Intense, an eco-friendly operation that knows every inch of this vast green escape, and also offers canyoning.
