Gulf Hagas

The “Grand Canyon of Maine”

Gulf Hagas is a dramatic 3.5-mile slate gorge carved by the West Branch of the Pleasant River within the KI Jo-Mary Forest. Designated a National Natural Landmark in 1968, the gorge features sheer walls up to 130 feet high, numerous waterfalls including Screw Auger Falls, Buttermilk Falls, Billings Falls, and The Jaws, plus deep swimming holes and pristine pools.

The Gulf Hagas rim trail follows the Appalachian Trail for part of its length and offers challenging but rewarding hiking with views of waterfalls at every turn. The area is accessed from the Head of the Gulf trailhead within KI Jo-Mary Forest.
