A harbor archipelago protects forts, trails, campsites, beaches, wildlife, and Indigenous history within sight of downtown Boston. The park’s meaning lies in connections across water: glacial drumlins became fishing grounds, quarantine stations, farms, military defenses, waste sites, and recreation landscapes.
Ferry schedules determine the day. Pick one primary island, reserve transport and camping separately, bring water and layers, and never assume another island can be added spontaneously. Weather cancels ferries and exposed crossings feel colder than downtown. Island surfaces include steep paths, stairs, ruins, ticks, and limited services. Even the skyline changes meaning when Boston is approached from its harbor.
