The lighthouse was built in 1907 and is still active today. The tower is 15 meters tall and its lights can be seen from almost 10 miles away (8nautical miles). The tower was built out of granite and bricks.

At the top of Mount Battie, you will run into a beautiful stone tower. It was built in 1921 at the spot where the 1898 Summit House hotel once stood. You can climb to its top and enjoy a beautiful view of Penobscot Bay, Camden Harbor, and Cadillac Mountains.

The ferry into Duck Harbor Campground is available from mainland Stonington early June through early October and costs around $44 round trip. The campground is your last place for amenities and water if you are running south! Outside of summer months the ferry runs only to the town on the north side of Isle au Haut and you will have to find their own way into the park. More information on the ferry: isleauhaut.com

The lot here is sizeable and has trail maps to guide you on your way. The trail crosses the road and then forks left for Bald Mountain or right for Little Ragged Mountain. If you are running up Ragged Mountain, this is one of the longer but less steep routes to take.
