NOTICE: Due to a forest fire in October of 2017, the DillyCliff Trail has been closed permanently. The cliffs can only be reachedfrom above by descending a short spur trail from the Kinsman Ridge Trail(Appalachian Trail) .

Located in the White Mountains town of North Woodstock, Lost River Reservation is set high in Kinsman Notch, one of the area’s most famous passes. Located between Mt. Moosilauke and Mt. Kinsman, Kinsman Notch isabout 2,000 feet above sea level. Lost River is so-named because the brook draining from the southeast part of Kinsman Notch disappears belowthe surface in the narrow, steep-walled glacial gorge. The gorge is partially filled with immense blocks of granite, through which the brookcascades along its subterranean course until it eventually emerges and joins the Pemigewasset River.

Today, the portion of the property that includes the gorge is leased to White Mountains Attractions Association, which provides guests with the opportunity to experience the fun, challenge, and excitement of the river, gorge, boulders and caves. Well-maintained boardwalks and staircases allow the public to access the gorge while providing the maximum amount of safety possible. Lost River Gorge welcomes thousands of visitors each year from all over the world. Visitors must pay a fee to enter the gorge; please visit the Lost River Gorge website fordetails. (New Forest Society members receive free passes to Lost River;if you're not already a member, please join and then come for an adventure!)

This trail is free and open to public recreation from spring through fall. The trail is not accessiblein winter, when the parking area for Lost River is gated and locked.
