A tough, much-loved hike in the park, the Precipice Trail feels a bit like a via ferrata, with its iron rungs hammered into the cliff face. Definitely not recommended for anyone afraid of heights (nor for inexperienced hikers), this scenic ascent up Champlain Mountain takes you along narrow ledges, up granite stairs and straight up cliff faces.
Allow about 3 hours to make the 3.2-mile return hike, which ascends 1000 vertical feet along the way. The trail is often closed from April to August to protect peregrine falcon nesting sites. Don't attempt this trail during rainy weather or with small children.
