In 1994 the U.S. Coast Guard licensed 32.5 acres comprising the New Dungeness Light Station to the non-profit New Dungeness Light Station Association. The remainder of the land is now the Dungeness National Wildlife Refuge managed by the U.S. Fish and Wildlife Service. Dungeness Spit is a product of the interaction between waters of the Strait of Juan de Fuca and the Dungeness River. The main arm of the Spit is the longest natural spit in the United States.
The Spit is also home or visited by over 250 species of birds, 41 species of land mammals and eight species of marine mammals. A complete check list for the wildlife is available. Hikers and boaters visit the lighthouse but must avoid restricted areas to protect the wildlife. (Download Wildlife Refuge Map)
