Ice Caves in Alaska 2025

A new unknown world is hidden under the majestic Alaskan glaciers

Best time: July–mid-September

It is hard to believe that such places exist on Earth. Here you can find tons of crystal clear ice, artistic shapes made by nature through millions of years, and soft sunbeams that barely pierce frozen walls… Looking at this miracle, only one thing may come to mind: it truly is a palace for a Snow Queen. The crystal ceilings look like the underside of a river frozen by a magician. These caves are probably the only one place in the world where you can see so many shades of natural blue.

The most famous Alaskan ice caves are located under Mendenhall, Root, Spencer, Matanuska, and Kennicott Glaciers. Many people from all around the world come to Alaska to see this natural phenomenon. It’s better to order a tour with an experienced guide (usually offered from July till September). Because of the greenhouse effect, ice caves tend to melt, therefore they may be dangerous for those who don’t know safe paths.
