The trail is very popular on the East Coast but it’s also one of the most dangerous in Acadia National Park. It’s not technically difficult but the steep drops and open cliffs make the walk very tricky. Don’t ever take your hands off the metal rungs. Stone steps, iron-rung ladders and steep slopes will take you up a sheer cliff face to the summit of Champlain Mountain. These walls were shaped 18,000 years ago when glaciers carved out the granite mountainside.
