A small wooded island just off downtown Bar Harbor, reachable on foot across a tidal gravel bar at low tide. The crossing itself is the attraction: bare ocean floor underfoot, mussel shells crunching, a low fog drifting in. On the island, a short trail climbs to an open ledge with the best view back at the town and the surrounding peaks of Acadia.
Check the tide chart before you go. The bar is walkable for roughly three hours total — about ninety minutes either side of low tide. The trailhead is at the north end of Bridge Street.
