America’s Most Sensational Granite Caves

The Polar Caves are granite boulder caves, with boardwalks carving a unique path through nine caves.


Discovery at Every Turn

Polar Caves is much more than a series of caves.  You can explore our animal area, try to get lost in the Rock Garden, BBQ/Picnic in our pine forest, and learn about Maple collecting techniques from the past.  Plus lots more!


Welcoming Environment

The Polar Caves are set on a cliff surrounded by a Pine forest. Most people choose to explore our caves at their own pace with a self-guided tour.  We also offer guided tours if you are interested in learning more about the caves and our park.


Educational Opportunities

Learn why New Hampshire is called the Granite State and how granite was originally harvested.  Learn how maple sap is collected and how it was used to make maple syrup in the earlier days in the Maple Museum.  Find gems, minerals and fossils in our mining sluice or hunt for crystals in the dark Klondike mines.


My 5- and 10-year-old boys yelled “This is awesome!” as soon as they climbed down into the first cave, and that pretty much sums up the Polar Caves experience. These are rough boulder caves, not huge underground chambers, such as Howe Caverns in New York. However, having been to both, I would say that the Polar Caves are even more fun in a different way because you can scramble and squeeze through the caves on your own and at your own pace. In fact, I was pleasantly astonished at how much freedom the owners permit here.
