Ledge Trail

What this hike is

The Ledge Trail is a short, very steep route up the west side of Mount Desert Island to Saint Sauveur Mountain. It climbs rugged granite ledges through mixed pine forest, then breaks out to open rock with sweeping views over Long Pond, Somes Sound, and the surrounding ridges. Expect a quick but punchy workout with real payoff and fewer people than Acadia’s headline peaks.

Distance, time, and route options

The Ledge Trail itself runs about 0.5 miles one way to a junction with the Saint Sauveur Mountain Trail. From there, a brief connector leads to the summit, making it roughly 0.9 miles one way (about 1.8 miles total as an out-and-back to the summit). Elevation gain is about 470 feet. You can keep it simple as an out-and-back or link with the Saint Sauveur Mountain Trail for loop options.

What to expect underfoot

The ascent starts steep and stays that way, with uneven, rocky footing and long stretches of bare granite. These ledges can be slick when wet, and icy conditions turn this into a serious undertaking. Trekking poles are helpful—especially on the descent. It’s not accessible, and it’s not a great intro hike for folks uncomfortable with exposure or rough footing.

Scenery and vibe

Much of the climb is shaded by classic Acadian pine and mixed forest, with hardy plants clinging to the ledges. As you gain elevation, the trees thin and views open up—look for big panoramas toward Long Pond and Somes Sound near the upper ledges and summit area. Compared to the park’s busiest peaks, this trail sees moderate traffic and can feel pleasantly quiet.

Logistics

Trailhead access is just off Route 102 (Main St) north of Southwest Harbor. The trail network here has multiple junctions—pay attention to signs and the map at the trailhead. Dogs are allowed on leash, but the steep rock and exposure aren’t ideal for every pup. No special permits are needed for day hiking; standard park entry fees apply.

Best time to hike

Late spring through fall is prime. The granite is slippery when wet and hazardous in snow or ice, so use extreme caution in winter. Sunrise or sunset light is fantastic from the ledges; bring a headlamp if you’re hitting low-light hours. Cell service can be unreliable around the park—download maps for offline use.

Good to know

This route is part of Acadia’s historic trail system. Keep to the marked path and practice Leave No Trace—the ledge ecosystems are fragile.
