Wilderness Landscape & Natural Heritage
Located off the coast of Eastham, Massachusetts, Sampson’s Island Wildlife Sanctuary consists of two uninhabited barrier islands that protect important salt marshes, sandy beaches, and tidal creek ecosystems. Managed by the Massachusetts Audubon Society, the sanctuary serves as a vital nesting ground for endangered and threatened shorebirds, including the piping plover and least tern. The islands formed naturally through shifting sands and currents, making them dynamic and important habitats in the region's coastal landscape. Human access is restricted, particularly during breeding season, to safeguard sensitive wildlife populations. However, visitors can observe the sanctuary from adjacent viewpoints and nearby trails within the Fort Hill area of Cape Cod National Seashore. The sanctuary’s isolation creates a refuge for migrating shorebirds and other coastal species, with seasonal visits by seals and occasional shorebird species. Environmental education and research are key components of the sanctuary’s mission, with efforts focused on habitat restoration, invasive species control, and protecting nesting areas from disturbance. While camping and direct trail access on the island itself are not available, the surrounding Cape Cod National Seashore offers ample opportunities for hiking, beachcombing, photography, and shorebird watching, especially during spring and summer. Sampson’s Island stands out as a vital coastal sanctuary where conservation and responsible public appreciation intersect on one of Cape Cod’s most ecologically significant barrier islands.
