Acadia National Park, on the coast of Maine, offers something few climbing areas in the United States can: routes that start right above the ocean. Otter Cliff and Great Head drop into the Atlantic, and climbers rappel down to the base and climb back up with the waves below. The park also has inland cliffs with multi-pitch routes, all on solid pink granite.
The rock
According to the National Park Service, most cliffs in Acadia are made of solid, coarse-grained pink granite, and the longest routes are three pitches. The park describes Otter Cliff and Great Head as a spectacular setting for sea cliff climbing not commonly available elsewhere.
The main climbing areas
- Otter Cliff: 60-foot sea cliffs with crack and face climbing, reached by rappel, with routes up to 5.12.
- The Precipice (Center, Left, Right and Lower walls): three-pitch routes up to 5.12, with good corners and thin cracks and some good beginner routes.
- South Bubble: one- to three-pitch routes, some friction climbing and good beginner routes.
- Great Head: harder sea cliff climbing, also reached by rappel.
The park adds that good bouldering can be found along the ocean between Sand Beach and Otter Cliffs, and near Blackwoods Campground.
Tides decide the day
On the sea cliffs, the ocean is part of the route. The Park Service says climbers at Great Head and Otter Cliffs should know the tides and the weather forecast, because climbing there is more difficult and more dangerous at high tide or with high surf. Plan your session around low tide, and keep an eye on the swell, which can reach the base on calm-looking days.
Anchors at Otter Cliffs
At the top of Otter Cliffs, the park maintains fixed anchors that must be used instead of trees to belay several climbs. This protects the thin soil and the trees along the cliff edge. The park asks climbers to inspect these anchors before use and to report any safety concerns immediately. Elsewhere, local climbers maintain some fixed protection and rappel stations, and those also need checking before you trust them.
Group size and permits
- Climbing groups must be 12 people or fewer, guides and instructors included, at any climbing area and in any season.
- At Otter Cliffs, organized groups of 6 to 12 people must reserve a climbing permit from the Friday before Memorial Day through Labor Day.
- Anyone offering guiding or instruction for a fee needs a Commercial Use Authorization. Guiding is available from private companies in Bar Harbor.
Peregrine falcon closures
The Precipice parking lot wall, Jordan Cliffs and Beech Cliffs are usually closed to protect nesting peregrine falcons between early April and mid-August. Exact dates and locations vary from year to year. If you plan to climb on the Precipice in spring or early summer, check the closures first.
Other rules
- Climbing and bouldering are prohibited on all park bridges.
- Dogs are prohibited at climbing areas in the sense that they must not be tethered or left to run loose while their owner climbs.
- New routes with fixed protection, and route cleaning, need prior written approval from the superintendent, and are allowed only at a list of named cliffs.
Getting to the cliffs
Otter Cliff sits along Ocean Drive, part of the Park Loop Road on Mount Desert Island, and the park publishes a separate safety page for that stretch of coast. You need a park entrance pass to drive the loop. Parking near the sea cliffs is limited and fills early in summer, so arriving before the main wave of sightseers makes the day easier. The Precipice and South Bubble are reached from their own trailheads inland, a short drive away.
When to climb
Coastal Maine has short, mild summers and long, cold winters. The main climbing season runs from late spring to autumn. Fog rolls in off the ocean often, and wet granite above the sea is no place to push your grade. Autumn brings dry, clear days and fewer crowds, once the summer season ends.
Before you go
- Bring a tide table and check the surf forecast.
- Carry two ropes or a long rope for rappel access at the sea cliffs, and know the length of your rappel.
- Expect crowds at Otter Cliff on summer weekends, and arrive early.
- A guidebook is recommended. The park cites Rock Climbs of Acadia, published in 2015.
