Lake Superior Ice Caves - Apostle Islands National Lakeshore

Extreme cold temperatures this winter has created a glorious display of ice formations along the Apostle Islands National Lakeshore at the northern most tip of Wisconsin. Only accessible by boat in the summer, the lake ice is thick enough this year to access the Lake Superior Ice Caves on foot. It's well work the journey, the single digit temperatures, and the 1.5 mile trek on the ice. Mother nature at her best, the Lake Superior Ice Caves are a true natural wonder.
