America’s Most Sensational Granite Caves

Formed by a glacier, The Polar Caves consist of nine amazing granite boulder caves now connected by boardwalks for easy exploration. 

Discovery at Every Turn

There is so much to discover at Polar Caves Park! Bring a picnic or plan to barbecue in our Pine Forest … there’s a lot to do. Feed the animals in the animal area, try to get lost in the Rock Garden, and learn about the history of Maple sap collection. Plus much more!

Welcoming Environment

At Polar Caves Park, we want you to leave the hustle and bustle behind. The Polar Caves are set on a cliff surrounded by a forest of pine trees. Most visitors choose to explore the caves at a relaxed pace with a self-guided tour. If you are interested in learning more about the caves and the park, please request a guided tour. We’d love to explore with you!

Educational Opportunities

Why is New Hampshire called the Granite State? How was granite originally harvested? At Polar Caves Park, you can find these answers and also:
• learn about the history of maple syrup production,
• mine for gems, minerals, and fossils in the mining sluice,
• 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.
