Big Four Ice Caves
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.
