The fascinating Lost River Gorge and Boulder Caves in the White Mountains were carved out of the earth by wind, water, and massive receding glaciers during the Ice Age. Today you can explore this beautiful gorge on foot along a boardwalk, or you can be more daring and venture into some of the many caves.

Joining one of the regular sun-set guided Lantern Light Tours is a highlight of any visit to Boulder Caves. In addition to the boardwalk path, you can also hike the Kinsman Notch Ecology Trail and the Nature Garden Walk, and experienced fit hikers can take on the Dilly Cliff Trail. Children can pan for gemstones or join the Junior Gorge Guide program. The Gorge is open from May to October.
