Located in the Cascade Range of Washington, the Big Four Mountain trail’s illustrious caves make it one of the most popular hiking destinations in the state. The mountain itself is over 6,000 feet tall and its staggering ice caves are created during the summer when snow melts and causes ice debris to pile up.

Intricate Ice Caves: Vatnajökull, Iceland

Vatnajökull Iceland

With pristine blue ice caves located inside of it, Vatnajökull is the largest glacier in Iceland. The glacier and the caves maintain centuries old ice and are able to be enjoyed thanks to the ice that flows from the region’s tallest active volcano.
