Apostle Islands Ice Caves, Wisconsin, USA

Walk on water to reach these remote caves carved in the ice

Walk on water into the mouth of danger.

Getting to this place is all about timing. Sculpted out of sandstone and glaciers, the Ice Caves of Apostle Islands are formed out of cliffs that tower over Lake Superior – and the only way in is to walk across it.

In the winter, the lake freezes over – if it’s thick and stable enough, you can hike straight into the mouth of the cave. Once inside, deadly-looking icicles hang like teeth off the cliffs overhead, standing out bright against earthy sandstone. Below you, the depths of the frozen lake are visible through the glassy floor.

The ice formations are different every year, depending on the weather – and so is the route in. With the sun shining through the mouth of the cave, your Ray-Ban Chromance lenses will help you focus the shocking white light so you don’t miss a single detail.
