Skalistý potok is a remarkable cave tucked beneath the southern edge of the Jasov Plateau — the longest and deepest cave in the entire Slovak Karst. Its vast underground system of passages, waterfalls, siphons and rapids makes it one of the most awe-inspiring subterranean environments in Central Europe.

The cave has a raw, untamed character that sets it apart from any tourist-friendly show cave. A real underground stream carves its way through more than seven kilometres of rock, dropping a dramatic 336 metres in total vertical relief. The main horizontal gallery stretches all the way towards the village of Háj, and the system is also connected underground to the neighbouring Kunia Abyss. This is a place where the earth truly opens up beneath your feet.

• The nearest village is Háj, in whose cadastral territory the cave is located — access must be arranged in advance with the Slovak Karst National Park administration.

• The cave is not open to general tourists — entry is permitted only for speleological groups holding an official permit.
• Since 1995, the cave has been part of the UNESCO World Heritage Site 'Caves of Aggtelek Karst and Slovak Karst'.
• Since 1996, it has been protected as a National Nature Monument of the Slovak Republic.
• Managed by Správa slovenských jaskýň (Slovak Caves Administration).

Here is a fascinating detail: Skalistý potok is hydrologically connected underground to the Kunia Abyss nearby — a reminder that the karst labyrinth beneath Slovak Karst is far more interconnected and mysterious than anything visible on the surface.
