Cadillac Mountain South Ridge Trail

The Cadillac Mountain South Ridge Trail is approximately 7.1 miles round trip with an elevation gain of about 1,350 feet. Hikers typically spend 3–5 hours completing the route, which is rated from moderate to advanced due to rocky, uneven terrain and occasional iron rungs.

The trailhead is on Maine Route 3, just west of Otter Creek and directly across from the Blackwoods Campground entrance. Roadside parking is available but fills up quickly during peak season. For a car‑free option, the fare‑free Island Explorer bus stops at Blackwoods Campground, putting you within a short walk of the trailhead.

Dogs are permitted on the South Ridge Trail but must remain on a leash no longer than 6 feet at all times. Be aware that some sections include rocky scrambles and an iron rung, which can be challenging for pets.

The South Ridge Trail itself offers no restrooms, water fountains, or shelters. At the summit, you’ll find paved restrooms, a small gift shop, and interpretive signs along the short Summit Loop. A park entrance pass (or $10 per vehicle fee) is required for Cadillac Summit Road from mid‑May through mid‑October.

Hikers should pack ample water, snacks, a detailed map or GPS device, and layered clothing for sudden weather changes. Good‑traction footwear is essential on uneven granite surfaces. Stay on marked paths or follow cairns to avoid getting lost, perform tick checks after the hike, and watch for changing conditions—especially wind and rain at higher elevations.
