Key West National Wildlife Refuge (Key West NWR) is among the first refuges established in the United States. President Theodore Roosevelt created the refuge in 1908 as a preserve and breeding ground for colonial nesting birds and other wildlife during the time when plume hunters were devastating bird populations throughout Florida.

Key West NWR is located west of the city of Key West, Florida, and is accessible only by boat.

The refuge consists of the Marquesas Keys and 13 other islands spread across 375 square miles of open water.  Most islands are dominated by mangrove plant communities. Exceptions are the hardwood hammock in the Marquesas Keys and the beaches and dunes on Marquesas, Boca Grande, and Woman Keys. All islands lack freshwater.

National wildlife refuges offer us all a chance to unplug from the stresses of daily life and reconnect with our natural surroundings 

Key West NWR is truly one of nature's masterpieces, encompassing thousands of acres of shallow saltwater and mangrove island habitat. The refuge waters are open 24 hours a day, 365 days a year for water-based activities such as boating, fishing, wildlife viewing, photography, snorkeling and diving.   

Key West NWR is accessible only by boat. To reach the refuge, visitors with boats can use a variety of public and private boat ramps throughout the Lower Florida Keys.  Private charter fishing and eco-tour services are also available and are a great way to visit the refuge if you don’t have your own boat. 

A great place to start your visit is at the Nature Center for the four Florida Keys NWRs, located at 30587 Overseas Highway on Big Pine Key.

      About Us

      The refuge consists of thousands of acres of open shallow saltwater and mangrove islands, and is known locally as “the backcountry." The refuge provides nesting, feeding, and resting areas for wading birds, shorebirds, raptors and hundreds of other species of birds. Several species of sea turtles (loggerhead, green and hawksbill) forage here and nest on the beaches within the refuge. Florida manatee and Atlantic bottle-nosed dolphin are commonly seen within the shallow waters. The last wild populations of the endangered Miami blue butterfly are found in this refuge.

      With few exceptions the refuge’s backcountry islands are pristine uninhabited islands in federal ownership. All of the islands within the refuge (except Ballast Key) are part of the federal National Wilderness System.

      The USFWS co-manages the submerged lands managed by the State of Florida through a Management Agreement for Submerged Lands within Boundaries of the Key West and Great White Heron NWRs (Management Agreement). Adopted in 1992, the Backcountry Management Agreement prohibits the use of certain watercraft and activities and creates zoning regulations for certain islands. The Service also partners with NOAA’s Florida Keys National Marine Sanctuary to manage these islands that are formally refered to as "Wildlife Management Areas".
