Thing to Do
Hike Perpendicular and Razorback Loop

The Perpendicular and Razorback Loop features a steep hike up to the summit of Mansell Mountain on the west side of Mount Desert Island. Although the trail and summit are mostly wooded, it is a quieter, strenuous hiking opportunity. The Perpendicular Trail was built by the Civilian Conservation Corps (CCC) from 1933 to 1934. Flat boulders were laid end-to-end to form an easier walking path over the talus slope and rock steps were also added. The crew covered stones with moss and planted ferns to help them blend with their natural surroundings.
