QUICK TRAIL FACTS

  • Preserve Size: 70 acres
  • Trail Mileage: 1.5-mile loop
  • Pets: yes
  • Difficulty: easy
  • Sights: historical spots, pretty campsites, islands, bays, three miles of shoreline

A wide, fairly level track circumnavigates this public 70-acre island close to Islesboro. The track serves both as a path for the remote camper who must lug their stuff to one of the 12 amazing, remote seaside camping spots, as well as for day visitors who stop by to explore. I recommend hiking the 1.5-mile island loop trail clockwise, as it’s easier to follow the perimeter trail this way. You can reduce the length of your hike by cutting through the 0.2-mile interior shortcut.

Directions: There is no ferry or public boat service to the island. One way to get to the island is to take a ferry to Islesboro with a kayak or canoe strapped to your car and (bravely) boat the short distance to the island’s dock from the ferry terminal. The sea can be rough at times, but I did see some people make the trip in a canoe. Wear life jackets! And only do this in the summertime. Or, if you have your own motor or sailboat, find a launch from the mainland.

Let me know if you have any trail updates or corrections!
