Ice diving is a form of adventure tourism activity that takes place under ice, typically in frozen lakes or seas.

Divers cut a hole in the ice to enter the cold, clear water.

Many risks are involved, such as the need for controlled exits, limited entry points, and cold temperatures, which require specialized training and equipment.

Some spots where you can try it are the White Sea and Lake Baikal in Russia, Silfra glacial water in Iceland, Tasiilaq fjord in Greenland, and McMurdo Sound in Antarctica.
