About this Collection

Congressionally designated wilderness can be found on 63 national wildlife refuges in 26 states. About 90 percent of the Refuge System’s wilderness is in Alaska. In the lower 48, some refuge wilderness areas — such as those at Great Swamp National Wildlife Refuge in New Jersey and Cape Romain National Wildlife Refuge in South Carolina — are located surprisingly near urban centers.

Here is the list by state of the 63 national wildlife refuges that have wilderness areas.
