Ice Caves

Apostle Islands Ice Caves

Centuries of waves freezing and thawing along the sandstone bluffs of Lake Superior have formed the sea caves of the Apostle Islands National Lakeshore. Ice formation and colors change from chamber to chamber in each of the caves. Blue ice is formed when the ice is dense and bubbles do not interfere with the passage of light. Ice appears pink when reddish grains from the sandstone cliffs are embedded in the ice.

An hour drive from the Bluffs Inn, the mainland ice caves of the Apostle Islands National Lakeshore are accessible from the parking area at Meyers Beach. It is a 1.1 mile walk to the caves. The caves then extend an additional .6 - 1.2 miles along the shoreline.

Conditions can change quickly on Lake Superior. Visit the National Park Service website for current conditions and FAQs.
