Note: We highly recommend booking your group reservation at least a week in advance as we will continue to limit occupancy by hour, by day to improve out visitor experience on the trail and in the gorge. Reservations must be cancelled at least 24 hours in advance.

Groups should plan to spend about 2 hours exploring Lost River Gorge. In addition to climbing, crawling, and squeezing in and out of the 11 boulder caves, educational signage along the trail will share the natural and cultural history of the gorge. Topics of interest include the role water played in shaping and forming the gorge, the geology of Lost River Gorge, the discovery and protection of Lost River as well as information on the flora and fauna abundant among the rocks and boulders. Lost River provides a fun, hands on learning experience in one of the most magnificent outdoor classrooms in New Hampshire!

This half-mile, self-guided loop trail is of easy to moderate hiking difficulty.
