Twenty percent of the land in the Dominican Republic has been set aside for preservation, helping to ensure that visitors can experience the island's incredible ecological diversity. In all, the Dominican Republic boasts 19 national parks, 32 national monuments, six wildlife reserves, and two marine sanctuaries. Here are some of the best:
Whale Sanctuary, Samana
The Dominican Republic's Sanctuary for the Marine Mammals is conveniently located near one of the island's most popular tourist areas, Samana. Stretching between Christmas Bank and the Bay of Samana, the sanctuary encompasses the largest mating, courting and calving grounds in the world for the humpback whale. Whale-watching cruises can be chartered out of Samana Bay.
Los Haitises National Park
Also near Samana is Los Haitises National Park, famous for its mangrove coastline, caves, and petroglyphs. Horseback tours through the park lead visitors to Fun Fun Cave, where amateur spelunkers can rappel 60 feet down to explore the underground environment.Cabritos Island National Park
Surrounded by Lake Enriquillo, the largest saltwater lake in the Caribbean, and the Dominican Republic's lowest point (144 feet below sea level), this park in the country's southwest is home to American crocodiles, flamingos, and iguanas. An early morning or late afternoon boat tour around the island is the best way to see the crocodiles.
