The Crystal River National Wildlife Refuge is part of the United States National Wildlife Refuge System, located in Kings Bay, in the town of Crystal River, and consists of 20 islands and several small parcels of land. The 80-acre (320,000 m2) refuge (only accessible by boat) was established in 1983, to protect the West Indian Manatee. It is administered as part of the Chassahowitzka National Wildlife Refuge Complex.
This is the "Kings Spring" area. The area behind the buoys and ropes is a manatee sanctuary, where snorkelers and boaters are forbidden to enter.
