Maine Coastal Islands National Wildlife Refuge

4.4Free

Explore pristine island sanctuaries and coastal wilderness along Maine's rugged coastline.

Maine Coastal Islands National Wildlife Refuge protects over 60 offshore islands and coastal mainland parcels along the coast of Maine. Though distinct from nearby Acadia National Park, this sprawling sanctuary safeguards vital nesting habitats for seabirds like Atlantic puffins and terns. Visitors can explore scenic mainland hiking trails, view marine wildlife, or learn more at the refuge visitor center in Rockland.

Quick tip: Check seasonal restrictions before visiting, as many nesting islands are closed to human access from spring through late summer to protect breeding birds.
