What to Expect

Giant Slide Loop earns its name in the first mile — you'll scramble up a narrow ravine choked with house-sized boulders, using iron rungs and your hands to haul yourself through a granite obstacle course that feels more like canyoneering than hiking. The ravine is shaded and mossy, almost cave-like in places, before the trail spits you out onto open ledges where the character shifts completely. From Sargent Mountain's bald summit — the second highest point on Mount Desert Island — you get a full sweep of Jordan Pond, Eagle Lake, and the ocean beyond, with none of the crowds that swarm Cadillac. The loop back over Gilmore Peak and Parkman Mountain adds two more summits without much extra effort. This is the trail for hikers who think Acadia's marquee routes are too tame and want something with real grit.

Safety Advisory

The ravine scramble involves exposed iron rungs and steep rock faces with significant fall potential — this is not a trail where you can zone out with earbuds. Hands-free is essential; use a pack, not a handheld water bottle.

The trail crosses private land at the start. Wandering off-trail here risks losing access for everyone — stick to the blazes and keep noise down.

Despite the wheelchair-accessible tag at the trailhead area, the Giant Slide route itself involves Class 3 scrambling and is absolutely not accessible beyond the first few hundred yards.

Pro Tips

Trail Tip

Start early from Route 198 — the small roadside pulloff fills fast and there's no overflow. If it's full by 8 AM on a summer weekend, you waited too long.

Trail Tip

The boulder scramble in Giant Slide ravine is significantly harder when wet. Check the forecast and skip this route after rain — the lichen-covered granite becomes genuinely slippery.

Trail Tip

Run the loop clockwise (up Giant Slide, down via Parkman) so you tackle the technical scrambling on the ascent when your legs are fresh. Descending those boulders is harder on the knees and riskier.
