Frequently Asked Questions

How hard is the Gulf Hagas hike?

The full Gulf Hagas loop is 8 miles and strenuous — rocky, rooty, and with river crossings. The reward: stunning slate gorge with waterfalls at every turn. Allow 5–6 hours. The Rim Trail offers the best views into the canyon.

What is Gulf Hagas?

Gulf Hagas is a 3-mile-long, 500-foot-deep slate gorge on the West Branch of the Pleasant River — called the “Grand Canyon of Maine.” Multiple waterfalls cascade through the narrow gorge, and the AT passes nearby. The hiking trail along the rim is challenging (8-mile loop) but spectacularly rewarding. The remoteness keeps crowds small — you may have the gorge to yourself.
