America's Most Beautiful Coastal Walks
Precipice Trail, Mount Desert Island, Acadia National Park, ME
The nearly 1,000 foot climb up the East face of Champlain Mountain packs big thrills into a short distance. The trail is mostly vertical, with boulders acting as your stairs and the occasional iron handhold to assist your climb. The payoff is in the scenery: endangered peregrine falcon nesting in the rock crevices, the Cranberry Islands, and glorious views over the Maine coast.
Challenge Level: Strenuous.
Essential Gear: Worried about getting lost on a challenging trail? This watch not only tells time and monitors a workout, it is GPS enabled to help map your way back to the beach. (Garmin; $349.)
