Wilderness Landscape & Natural Heritage
St. Lawrence Islands National Wildlife Refuge spans more than 2,300 acres along the international border between the United States and Canada within the Thousand Islands region of northern New York. The refuge is composed of over 100 islands, shoals, and mainland parcels that provide critical habitat for a variety of migratory birds, fish species, and other wildlife. The refuge terrain ranges from rocky shores and sandy beaches to dense hardwood forests and wetlands. Its location in the St. Lawrence River corridor creates a biologically productive environment supporting endangered species such as the eastern massasauga rattlesnake and diverse populations of waterfowl and wading birds. Established in 1908, it was originally created to protect nesting habitat for colonial waterbirds and valuable fish spawning grounds. Today, the refuge is a popular destination for birders targeting species like bald eagles, herons, and terns, as well as anglers seeking bass and muskellunge. Boaters can explore numerous small islands by canoe or kayak, while anglers and wildlife photographers enjoy quiet access points along the shoreline. Unlike many traditional parks, much of the refuge is accessible only by watercraft, appealing to visitors seeking solitude and nature immersion. The refuge also preserves historic lighthouses and fishing camps scattered among the islands that reflect the region’s cultural heritage. Seasonal closures protect nesting birds and other vulnerable wildlife areas, making timing important for recreational visits. Overall, the St. Lawrence Islands National Wildlife Refuge is a vital sanctuary for regional biodiversity and a unique setting for low-impact outdoor recreation in a striking riverine environment.
