Isle au Haut Lighthouse is on the western shore of Isle au Haut in Penobscot Bay, Maine. The land around the Lighthouse is privately owned. Therefore, Isle au Haut Lighthouse is not open to recreational visitors without invitation. 

The Lighthouse is best viewed up close from the water, however, there is no public dock. During the summer, the Isle au Haut Boat Services mail boat runs right by the Lighthouse several times a day on its way to Duck Harbor in Acadia National Park providing great photo ops. Contact the boat company for seasonal schedules.
