Hiking

Acadia National Park maintains more than 150 miles of hiking trails, from easy strolls around lakes and ponds to rigorous treks with climbs up rock faces and scrambles along cliffs. Although hiking trails are concentrated on the east side of the island, the west side also has some scenic trails. For those wishing for a longer trek, try the trails leading up Cadillac Mountain or Dorr Mountain; you may also try Parkman, Sargeant, and Penobscot mountains. Most hiking is done mid-May–mid-November; snow falls early in Maine, so from as early as late November to the end of March, cross-country skiing and snowshoeing replace hiking. Volunteers groom most of the carriage roads if there’s been 4 inches of snow or more. Every few years, someone falls off one of the park's trails or cliffs and is swept out to sea. There is a lot of loose, rocky gravel along the shoreline, and sea rocks can often be slippery—so watch your step.

Acadia Mountain Trail. If you're up for a challenge, this is one of the area's best trails. The 2.5-mile round-trip climb up Acadia Mountain is a steep and strenuous 700-foot climb, but the payoff views of Somes Sound are grand. If you want a guided trip, look into ranger-led hikes for this trail. This is the only mountain on Mount Desert Island that lies east–west rather than north–south. Difficult. Rte. 102, Acadia National Park, Maine, 04609. 207/288–3338; www.nps.gov/acad.

Ocean Path Trail. This easily accessible 4.4-mile round-trip trail runs parallel to the Ocean Drive section of the Park Loop Road from Sand Beach to Otter Point. It has some of the best scenery in Maine: cliffs and boulders of pink granite at the ocean's edge, twisted branches of dwarf jack pines, and ocean views that stretch to the horizon. Be sure to save time to stop at Thunder Hole, named for the sound the waves make as they thrash through a narrow opening in the granite cliffs, into a sea cave, and whoosh up and out. Approximately halfway between Sand Beach and Otter Cliff, steps lead down to the water, where you can watch the wave action close up. Use caution as you descend (access may be limited due to storms), and also if you venture onto the outer cliffs along this walk. Easy.
