Lost River Gorge & Boulder Caves

Explore one of New Hampshire’s greatest natural wonders at Lost River Gorge & Boulder Caves, as you travel a self-guided adventure along their 1-mile wood boardwalk trail.

Traverse rock-strewn glacial boulder caves and jagged rock walls. Pan for gemstones in the mining sluice. Discover a treehouse, a suspension bridge, and cascading waterfalls. And elevate your experience with a climb to (and a selfie in) the Giant Bird Nest. You’ll soon see how “gorge-ous” this place can be!
