Warren Island State Park, near Islesboro


  • 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 state-owned 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 lovely 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 .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!
