PASSAGE KEY NATIONAL WILDLIFE REFUGE 1502 S.E. Kings Bay Drive Crystal River, Florida 34429
One of the first national wildlife refuges, Passage Key National Wildlife Refuge was established in 1905. This 30-acre meandering barrier island was once a mangrove island with a fresh water lake but a hurricane in 1920 had destroyed most of the island. The island hosts the largest royal tern and sandwich tern colonies in the state of Florida.
