Western Head Trail is a 1.5-mile point-to-point coastal leg on Isle au Haut, running north from its southern junction with Cliff Trail to Western Head Road. It crosses boulder beaches, bare granite and short forested walk-arounds. The mapped segment is one way; published figures differ from 1.3 to 1.6 miles, while the named path measures about 1.5 miles.
The practical full outing starts at Duck Harbor Boat Landing: follow Western Head Road south to Cliff Trail, walk the rocky southern coast, then continue north on Western Head Trail and return to Duck Harbor along the road. That connected loop is about 4.7 miles; the number above is only the Western Head segment. Allow about 1¼ to 1½ hours for this leg, longer for the full loop or unhurried beach stops.
The route alternates wooded walk-arounds with cobblestone strands and exposed granite. It has repeated short ups and downs rather than a big climb, and the rough footing makes it slower than the distance suggests. At beach crossings, look across for cairns marking where the path continues. For a photo, keep the cobbles and granite in the foreground with open water and the low wooded coast behind; a tight crop loses the shape of the shore.
Duck Harbor is reached by passenger ferry, and its stop is seasonal, generally mid-June through late September; check the current sailing schedule before planning the walk. Isle au Haut has few services: a small store and post office are by Town Landing, away from this route, and the campground facilities are at Duck Harbor rather than along the trail. Pets are allowed for day hiking on Isle au Haut, but must stay on a leash no longer than six feet. The island averages cooler temperatures than the mainland, so bring layers and rain protection.
