Duck Harbor Mountain and Western Head Loop

Access to Isle au Haut, where this loop is located, is exclusively by mail boat from Stonington, Maine. The trail itself starts and ends near Duck Harbor, which is one of the mail boat's stops.

This loop is generally considered a strenuous or moderately difficult hike. While sections like the Western Head Trail can be easier, combining it with the Duck Harbor Mountain Trail significantly increases the challenge due to steep inclines, rock scrambles, and continuous elevation changes.

You'll encounter diverse terrain, including rooted and rocky paths, exposed granite, and narrow passages through spruce forests. The Western Head portion skirts the unspoiled southern shoreline with dramatic headlands and stony beaches. The Duck Harbor Mountain section involves ascending through a forest with some rock scrambling. Boardwalks are present in marshy areas.

Acadia National Park, including Isle au Haut, generally allows leashed pets on most trails. However, it's always best to check the official Acadia National Park website for the most current pet policies and any specific restrictions that might apply to this remote island section.
