Discover the awe that lives beneath the White Mountains at Lost River Gorge & Boulder Caves. Stewarded by the Forest Society since 1912, this one-mile boardwalk winds past thundering waterfalls, sheer granite walls, and 11 glacial...
Visitors consistently rave about the stunning natural beauty here, with boardwalks leading through a scenic gorge dotted with waterfalls and fascinating boulder caves. The attraction really shines for families with kids, who absolutely love crawling through the various caves and tunnels. Reviewers note that while some caves require hands-and-knees crawling, there are plenty you can skip if mobility is a concern, and the main walkway itself offers gorgeous views with plenty of benches for resting. The experience involves a good amount of stair climbing and can be moderately strenuous, though many describe it as manageable and worth the effort. The paths are well-maintained and the scenery is especially breathtaking during fall. Staff members are friendly and crowds seem well-managed even on busy holiday weekends. A few people mentioned the paths can get congested with slower groups, but overall the consensus is overwhelmingly positive. Many reviewers specifically recommend this over other area gorges, calling it more engaging and entertaining despite being pricier.
Me and my partner spent three hours here, we had so much fun!!! Neither of us are good in big crowds, so coming on a weekday morning in September was perfect for us. There were probably 5-6 other families but it was basically like having the whole place to ourselves because it’s so big. The lemon squeezer (one of the super tight caves) looks threateningly small but we both got “squeezed” and it was surprisingly really fun! The employee at the register in the gift shop was so friendly and kind. I would highly recommend this place, preferably during off season to spend time really enjoying each cave and the views. Note there are a LOT of stairs but the caves are optional.
