There are seven National Natural Landmark sites located within the U.S. Virgin Islands. Natural features represented include the only location within the U.S. and American Territories regularly used by the endangered leatherback sea turtle for nesting, the best remaining stands of mangrove within the Virgin Islands, and the only site in the world where the bivalve Barrettia and Titanosarcolite fossils are found together. All seven sites received NNL designation in 1980. Sites range in size from 17 acres to nearly 1,860 acres and are owned by a variety of landowners including U.S. Fish and Wildlife Service, U.S. Virgin Islands Department of Planning and Natural Resources, and private individuals.

Please remember, National Natural Landmarks (NNLs) are not national parks. NNL status does not indicate public ownership, and many sites are not open for visitation.
