The 20 Most Challenging Hikes in America, Ranked
12. Precipice Trail – Acadia National Park, Maine
Difficulty: Class 2.5
The Precipice Trail is one of Acadia National Park’s most thrilling hikes, offering an intense, near-vertical ascent up Mount Champlain. Though only 3.2 miles long, this trail gains 850 feet in elevation, with iron rungs, ladders, and exposed cliffside paths making it feel more like rock climbing than hiking. The steep drop-offs and narrow ledges require a steady head, making it unsuitable for those with a fear of heights.

For those who dare, the panoramic summit views are unbeatable, rewarding hikers with a true sense of accomplishment. Hikers should wear sturdy boots, travel light, and keep their hands free for climbing. The trail has a $30 park entry fee per vehicle ($15 for walk-ins and cyclists), making it accessible for thrill-seekers ready for an unforgettable challenge.
