For 1.5 hours before and after low tide, a gravel bar is exposed connecting the town of Bar Harbor and Bar Island. The bar provide opportunities for investigating small tide pools. Once on the island, the Bar Island Trail gradually ascends through the forest on an old road to various open sections with views of Bar Harbor and Frenchman Bay.

  • Distance: 1.9 miles round trip (gravel bar and trail)
  • Terrain: Rocks, gravel sand bar, old dirt road, forested path

Be cautious and aware of the tides, as the bar is otherwise covered by the ocean. If you walk over to the island and lose track of time, it is 9 hours until the bar emerges again to safely walk across.

Hike Description

  • Start the hike by walking down Bridge Street from West Street in downtown Bar Harbor. Before taking this hike, check the tide chart for Bar Island

  • Walk across the "land bridge" for .5 miles towards Bar Island.

  • Once on the island, continue past the trailhead signs and onto the Bar Island Trail.

  • The trail gradually ascends through the forest on an old road.

  • At the next junction, turn right for a short spur to an old home site with a view of Bar Harbor.

Trail Safety Tips

  • The land bridge to Bar Island is exposed at low tide. The opportunity to hike occurs between the window of time 1.5 hours before to 1.5 hours after low tide.
  • Reduce the chance of picking up ticks by staying in the center of the trail, and not stepping on soils and away from brush.
  • Always do a tick check after visiting the park.
  • Closed-toe, good traction shoes recommended because most trail surfaces are very unlevel.
