The Polar Caves took shape during the last Ice Age as the last continental glacier rolled over what is now New Hampshire's White Mountains.
Fifty thousand years ago, a continental glacier moved southward over New Hampshire. As the ice sheet thawed, great blocks of granite fell from Hawk's Cliff. These massive granite blocks created a series of caves and passageways which you can come and explore. The park’s name refers to the “polar” breath that emanates from the caves even on the hottest summer day. Temperature differences between the air above ground and in the caves are why it’s a good idea to review our suggested attire.

Cool Fact: The largest glacially deposited granite boulder in the world landed at Polar Caves. Spanning a stunning 110 feet in length, the boulder towers 50 feet into the sky, is 75 feet thick and is estimated to weigh 50 million pounds – that’s 25,000 tons.
