Bar Island

Overview

Bar Island is the classic Bar Harbor experience: when the tide drops, a gravel-and-sand land bridge appears and you can literally walk across the ocean floor into a quiet, forested island in the park. It’s simple, novel, and very Maine.

What You’ll See

• A broad gravel bar dotted with tide pools, shells, and seaweed as you cross.
• A mellow path on an old road through pine and birch to the island high point (about 160 feet of gradual gain), with big views back to Bar Harbor and Frenchman Bay.
• Intertidal critters in the pools and coastal/woodland birds overhead.

How It Works (Tides!)

The land bridge is exposed only for a few hours around each low tide—roughly 1.5–2 hours on either side. Outside that window, the bar is underwater and Bar Island is, well, an island. If you mistime it, you’ll be stuck until the next low tide or paying for a water taxi.

Route & Logistics

• Start at the end of Bridge Street in downtown Bar Harbor and walk across the bar during the low-tide window.
• On the island, follow the signed path up to viewpoints, then return the same way before the tide floods the bar.
• There are no restrooms, water, or services—bring what you need and pack it out.

Rules, Parking, and Passes

• Do not park on the bar or on Bridge Street. Use paid public parking in downtown Bar Harbor (May 15–Oct 31) and walk to the crossing.
• In summer, carry a park entry pass when hiking the island.

Safety Notes

• Time your turnaround so you’re back across before the tide covers the bar. The incoming tide rises quickly and catches people off guard.
• Footing on the bar can be wet, rocky, and uneven—sturdy shoes help.

A Bit of Background

Bar Island is part of Acadia National Park today. Despite sitting just off Bar Harbor, a 1903 court decision placed it within the town of Gouldsboro. Historically it saw light use—sheep grazing, clam harvesting, and herring fishing—before the park era.

Geology Snapshot

The bar is a classic tidal spit shaped by strong currents and a roughly 12‑foot tidal range, revealing the crossing only at low tide.

Best Time to Visit

Aim for the low-tide window. It’s busiest in peak season and especially when low tide falls midday; if you want a quieter experience, avoid those midday low tides when possible.
