Pomázi kőfejtő Felső-barlangja, the Upper Cave of the Pomáz Quarry, is one of the most remarkable underground sites in the Pilis Mountains - a vertical fissure shaft plunging roughly 45 metres into the earth, hidden within an overgrown, disused quarry on the western edge of Pomáz. This is a destination for those fascinated by geology and cave systems, though it cannot be visited without official permission and proper caving equipment.

Inside, the cave reveals a striking sculpted world - walls deeply etched by the dissolution of Triassic Dachstein limestone, creating boxwork-like textures, delicate clay 'earth pyramids', and, deeper still, rare flowstone formations alongside fossilised Megalodus shells embedded in the rock. The cave descends in a series of steps through a narrow, jagged fissure, requiring several ladder descents and rope-assisted sections. The temperature inside stays steady at around 10.5°C year-round.

How to get there

• Pomáz, western edge of town - access through the abandoned quarry below the Majdán plateau, within the Duna-Ipoly National Park

Practical information

• The cave has strict protected status - entry is only allowed with permission from the Duna-Ipoly National Park Directorate
• Descent requires caving gear (ladders, ropes) and experience - this is not a casual hiking route
• A full visit takes experienced cavers roughly 1 to 1.5 hours

The cave has been progressively explored since the 1990s by the Anubisz Caving Group, who discovered its deepest chambers - including the striking Patakos-terem with its fossilised Megalodus shells - over the following decades.
