The 1997 Acadia National Park Climbing Management Plan recommended a reservation system for organized groups climbing at Otter Cliffs. The goal of the reservation system is to spread this group use out across the days of the summer to protect resources and provide a better experience for group and individual climbers.
Group Size Limit
The group size limit of 12 applies to all climbing groups using any park climbing areas at any time of the year. The purpose of this size limit is to reduce the effects of large groups on park resources and the climbing experience.
Reservations are required for organized commercial and noncommercial climbing groups wanting to climb at Otter Cliffs. They are not needed for groups of friends climbing together. The reservation season will run Memorial Day weekend to Labor Day. Two groups of up to twelve persons, including any guides or instructors, will be accommodated each day. Organized groups of five persons or less do not need a reservation for Otter Cliffs.
Complete a separate Group Climbing Request Form for each day you wish to climb up to a maximum of 10 days per organization. A lottery system will be used to process requests by the date received.
