One of the most famous ice caves in the world and the largest ice cave in Slovakia. Since 2000 it was included into the UNESCO World Heritage List. The ice filling has a volume of 110.132 m3 and occurs in the form of ground ice, waterfalls, ice stalagmites and columns. It was also the first cave in the Kingdom of Hungary with electric lighting.

Dobšinská Ice Cave has several magnificent parts – halls, corridosr and domes. The cave is also the lowest situated one in the world in terms of sea level altitude, which enhances its originality. Ice survives in the cave thanks to the form of the cave, which is similar to a sack.

Check the dates if you want to visit it because the cave is open May 15 - Sept 30 (except Mondays), every hour until 16:00.
