Hike St. Sauveur and Acadia Mountain Loop
What to Expect
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.
Trail Details
Pro Tips
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.
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.
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.
