Desecheo National Wildlife Refuge is a 360 acre island in the Mona Passage off the west coast of Puerto Rico. Although it is a relatively small island, the terrain is mountainous and rugged with semi-deciduous dry forest and grassland. Because of the porosity of the soils and the steep topography, there is no permanent freshwater on Desecheo.
This refuge is closed to the public
Desecheo National Wildlife Refuge is closed to the public due to the presence of unexploded military ordnance. Future access will be limited and will be contingent on cleanup of ordnance and certification that the area is safe for use.
