Chill Out: Polar Caves, New Hampshire

Top Ten U.S. Caves

The Polar Caves were formed about 50,000 years ago as the third continental glacier descended over New Hampshire's White Mountains. When the ice retreated, it left behind an amazing series of caves and passageways—marked by quartz veins, mineral deposits, and deep canyons—for visitors to explore. A family-friendly destination, Polar Caves Park includes a rock garden, nature trails, and a petting zoo—all set against the White Mountains. Self-guided tours take you through the rock garden and caves.
