What to Expect

This is one of the most uniquely timed hikes in the entire national park system. You start by walking across a gravel bar that literally emerges from the ocean — a land bridge connecting downtown Bar Harbor to a forested island that spends most of its day surrounded by water. The crossing itself is the spectacle: tide pools dotting the exposed gravel, seabirds working the shallows, and the surreal feeling of walking where boats floated hours earlier. Once on Bar Island, an old carriage road climbs gently through spruce forest to open ledges near the summit, where you get a postcard panorama of Bar Harbor's waterfront and Frenchman Bay stretching to the horizon. The whole thing takes about ninety minutes and gains barely enough elevation to notice. Perfect for families, first-time visitors, or anyone who wants a hike with a built-in conversation starter.

Safety Advisory

The tide is not optional scenery — it is the trail. If you misjudge your timing, the gravel bar floods to knee-deep (and eventually chest-deep) water. People get stranded on Bar Island every summer. Know your crossing window and respect it.

The gravel bar is slippery with seaweed and uneven rocks, especially near the edges. Wear shoes with actual traction — flip-flops are a rolled-ankle waiting to happen.

Pro Tips

Trail Tip

Check the Bar Harbor tide chart before you go — the bar is passable roughly 1.5 hours on either side of low tide. Set a phone alarm for your turnaround time so you don't end up waiting four hours on the island for the next low tide.

Trail Tip

Start from Bridge Street in downtown Bar Harbor rather than driving into the park. There's no parking lot at the trailhead per se — you're walking straight from town. Street parking fills fast in summer, so arrive 30 minutes before the bar exposes.

Trail Tip

The best views aren't at the official summit marker — keep walking past it to the open rock ledges on the southeast side of the island, where you get an unobstructed sweep of the Porcupine Islands and the full Bar Harbor skyline reflected in the bay.
