Petit Manan National Wildlife Refuge protects diverse coastal habitats along Maine’s rugged shoreline, offering excellent opportunities for wildlife observation, especially seabird and sea mammal viewing.
Established in 1974, Petit Manan National Wildlife Refuge is part of a larger complex of refuges along Maine’s coast that safeguard vital habitats for seabirds, migratory waterfowl, and marine mammals. The refuge encompasses more than 6,000 acres, including several offshore islands, salt marshes, tidal estuaries, and rocky coastlines, stretching from the mainland at Gouldsboro out to several key islands like Petit Manan Island, Egg Rock, and Franklin Island. These islands serve as critical nesting sites for a variety of seabirds, including Atlantic puffins, razorbills, common eiders, and Arctic terns. The refuge is managed by the U.S. Fish and Wildlife Service and forms an essential part of the Gulf of Maine ecosystem that supports both coastal and marine wildlife.
Recreation here focuses primarily on wildlife viewing—especially birdwatching during breeding seasons when thousands of birds return to the islands. Kayaking and boating opportunities exist, though visitors should be mindful of seasonal closures around nesting colonies to avoid disturbance. The coastal forests and marshes of the mainland portion also provide habitat for mammals such as black bears, white-tailed deer, and otters, and visitors can explore several short trails and observation points. The refuge’s remote islands offer striking views of the Atlantic and serve as a natural laboratory for coastal habitat conservation. Visitors are drawn to the refuge for its peaceful setting, excellent photography opportunities, and abundant wildlife encounters. Interpretive programs and guided tours are occasionally available through partnering organizations during peak seasons.
