Deep Cove Trail

This is a blink-and-you’re-there stroll through spruce–fir woods to a rocky cove on Isle au Haut’s quieter, more remote side of Acadia. It’s only about 0.2 miles with roughly 55 feet of elevation change (from ~30 to ~85 feet), and it feels more like a scenic detour than a standalone hike—perfect when you want a quick payoff without the crowds.

You’ll follow a short, natural path through mossy coastal forest before reaching Deep Cove, a small, tranquil inlet framed by granite and evergreens. Expect a natural tread underfoot that can be muddy after rain, with occasional cairns near the shore. The outing is easy and suitable for most hikers, but it is over fast—plan roughly 4 minutes each way for most people.

Keep an eye out for seabirds along the water and the occasional seal in the cove, with forest birds chattering in the trees. The bedrock here is classic Acadia granite, shaped by glacial forces that left the rugged coastline you’ll see at the water’s edge.

Best used as a quick add-on: it’s a short spur off the Duck Harbor Trail and pairs well with longer Isle au Haut routes (like Goat or Cliff) if you want to make a fuller day of it. Services are limited on the island, so come self-sufficient with water, sun protection, and bug spray, and download a topo map ahead of time.

Best time to hike: Late spring through early fall is most pleasant. Even in midsummer, the remote setting helps keep things quiet. Winter access is possible, but expect icy or snowy conditions and potentially slick rocks near the shore.

Bottom line: lovely, peaceful, and very short. If you’re already on Isle au Haut, it’s a worthy few minutes to a pretty cove. If you’re looking for a “destination” hike, stitch it into a longer Isle au Haut itinerary.
