With few exceptions the refuge’s backcountry islands are pristine uninhabited islands in federal ownership. Many of them have been designated 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".
National wildlife refuges offer us all a chance to unplug from the stresses of daily life and reconnect with our natural surroundings
Great White Heron NWR is truly one of nature's masterpieces, encompassing thousands of acres of shallow saltwater and mangrove island habitat. This Florida refuge extends from north of Marathon westward to just north of Key West, a distance of approximately 50 miles. 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.
Great White Heron 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.
