More than 110,000 cubic metres of ice are packed into the gleaming walls of this Unesco-listed ice cave, near the southern edge of Slovenský Raj National Park. Frosty stalagmites and chambers where tendrils of ice sparkle from the ceiling create an otherworldly atmosphere. The departure point is a half-hour walk from the car park, so arrive in good time ahead of guided tours (on the hour).
Cold air sinks through the cave mouth, concealed beneath Duča mountain, keeping temperatures around -3°C. In places, the cave ice is 25m thick.
Tours plying 515m of trails are in Slovak only, unless there’s a critical mass of Anglophones and plenty of advance warning.
