By | Last Updated: 29th November 2021

When talking about caves, New Hampshire may be mainly known for Polar Caves and Lost River Gorge and Boulder Caves. However, the Granite State features about 200 documented caves. The number only increases every year as new ones continue being discovered. In fact, Pawtuckaway State Park alone is home to more than 30 of them.

Exploring the caves of New Hampshire calls for an adventurous time for adults and children alike. You can easily access the large ones by a comfortable walk through the well-lit interiors. On the other hand, the small hole-like entrances and tight passageways require crawling and squeezing through them. Big or small, all these caves are sure to provide you with a fun experience once you visit them.
