Climbers assume responsibility for personal safety. On some routes local climbers maintain fixed protection or rappel stations. As always, evaluate them before using. At Otter Cliffs, the park maintains fixed anchors on top that must be used instead of trees to belay several climbs. Evaluate these anchors as well, and notify the park immediately of safety concerns. Climbers at Great Head and Otter Cliff should know tides and weather forecasts; climbing at these areas is more difficult and dangerous at high tide or in heavy seas. Climb within your limits.
Several climbing guidebooks are available locally.
A copy of A Climbers Guide to Mount Desert Island by Geoffrey Childs (1979 - out of print) is available for review at Hulls Cove Visitor Center and local libraries.
Otter Cliff: 60 feet (18 m) sea cliffs, crack and face climbing, rappel access, routes up to 5.12
Many other small areas are used infrequently. Good bouldering can be found along the ocean between Sand Beach and Otter Cliff, and near Blackwoods Campground.
