Lost River is a series of glacially formed boulder caves and potholes in spectacular beauty. The largest is 25 feet in diameter and 60 feet deep. Area geography causes the river to disappear resurfacing later. The river emerges at the foot of the gorge forming Paradise Falls.
Lost River in the White Mountains is nearby Woodstock NH. Kinsman Notch is one of the most well known passes in the area, with Crawford Notch, Franconia Notch and Pinkham Notch.
The name Lost River was chosen as the river disappears draining below the surface in the narrow, steep walled glacial gorge, flowing from the southeast part of Kinsman Notch. The river eventually emerges when it joins Pemigewasset River.
With logging operations prevalent in the 1900’s the beauty of the Lost River Gorge and area were becoming threatening. There was interest in preserving this natural wonder so Society for the Protection of New Hampshire Forests purchased Lost River in 1912 as Lost River Reservation.
The society welcomes thousands of guests from around the world to share this natural wonder. Visitors entering the gorge must pay a fee. Well-maintained boardwalks and staircases access various sections of the gorge while providing safety. Picnicking facilities are available. Proper shoes are important to provide surefooted movement in the canyon.
The gorges self-guided tour gives experiences such as a tight squeeze thorough Lemon Squeezer. One may stand under a rock formation called the Guillotine for a photographic moment. Tours through the canyon are only ¾ miles but last up to 90 minutes with much to see and experience.
The Appalachian Trail passes a short distance northwest of Lost River Reservation. The Appalachian Trail known as the A.T. is a 2,200-mile trail extending between Mount Katahdin Mountain Maine and Springer Mountain in Georgia.
Lost River begins at Kinsman Notch flows through the notch moving through Lost River Gorge. The stream is 6.5 miles long, a tributary of the Pemigewasset River part of the Merrimack River in New Hampshire’s White Mountains. Lost River starts at Kinsman Notch it passes through Lost River Gorge ultimately joining the Pemigewasset River in North Woodstock village.
