The Golfo Dulce is one of the most unique and interesting areas in Costa Rica. It is home to the largest rain forest in Central America. This unspoiled ecosystem is one of the few places in the world where rain forest covered slops drop directly into an ocean gulf. This combines the diversity and magic of tropical virgin rain forests, with the peace and beauty of private, secluded beaches, set around an incredible world of exotic marine life. The gulf, which is roughly 16 kilometers wide and 48 kilometers long, is very manageable by small boat, while offering an unlimited number of environments and opportunities to explore and discover your "tropical nature" at its best. It is truly quite incredible.
So primitive, so pristine is this uninhabited stretch of shore that Costa Rica has declared it a national treasure. Here, rain forests are so dense that 100 different kinds of trees exist on a single acre. And more bird species nest here than in the U.S. and Canada combined.
Costa Rica's unit of currency is the Colon.
