Walk across the Water to Bar Island
Starts: 05/01/2026 - Ends: 10/19/2026
Most of the time it looks like a boat would be needed to hike on Bar Island. But twice a day at low tide, a natural bridge appears which leads to Bar Island, Acadia National Park. The natural land bridge connects Bar Harbor, at Bridge Street, to Bar Island making it accessible by foot, bikes, and all-terrain or other types of vehicles. To be safe, plan on having no more than 1.5 hours before and after low tide. Otherwise, you could get stuck on the island waiting for the next low tide to return.
