What to Expect

This loop packs a serious punch for under four miles. You'll climb through dense spruce-fir forest before the canopy opens onto bare granite slabs that demand your full attention — and reward it with some of the finest views on Mount Desert Island's quieter west side. The first summit, St. Sauveur, gives you a warm-up panorama, but the real showstopper comes on Acadia Mountain's ridge, where Somes Sound — the only fjord on the East Coast — carves a deep blue gash between the mountains below you. You'll see the Cranberry Isles scattered across the horizon and, on clear days, the Camden Hills fading into the distance. The descent via Man o' War Brook trail drops you back through cool forest to the road. This is a hike for anyone who wants legitimate mountain views without an all-day commitment — but be ready for some scrambling that will make your hands as useful as your feet.

Safety Advisory

Multiple sections cross exposed granite slabs near cliff edges with no guardrails — skip this trail after rain or when surfaces are icy, as wet granite is genuinely treacherous.

One iron rung ladder section requires upper body effort and is not suitable for very young children or dogs with short legs. The exposure beside it is real, not decorative.

Pro Tips

Trail Tip

Hike the loop counterclockwise (St. Sauveur first) — the steepest granite slabs are easier to climb up than descend, and you save the best Somes Sound views on Acadia Mountain for the second half.

Trail Tip

Park at the Acadia Mountain trailhead on Route 102 early — the small lot fills by 9 AM in summer. The Island Explorer bus (Route 7 Southwest Harbor) stops nearby if you'd rather skip the parking lottery.

Trail Tip

Linger on Acadia Mountain's south-facing ledges for the best photography light in late afternoon, when the sun hits Somes Sound at a low angle and the water turns molten gold.
