Pál-völgyi Cave System

The Pál-völgyi Cave System is a limestone network beneath the Buda Hills featuring narrow passages, spacious chambers, and mineral deposits throughout its structure. The underground labyrinth spans multiple levels and displays natural geological formations created over millions of years.

The cave network was discovered in 1904 during blasting operations at a quarry near Szépvölgyi Road. Researchers explored it and opened sections to the public starting in the 1910s.

The name refers to the nearby Pál Valley in the Buda Hills where the system sits. Visitors can see the marked pathways and research installations that scientists have built over many decades to make the caves accessible.

The cave maintains a steady temperature of about 11 degrees Celsius year-round, so bring warm clothing and sturdy hiking boots. Guided tours are required and demand reasonable fitness, as there are steep stairs and tight spaces to navigate.

Visitors must climb over 400 steps and navigate a 7-meter-high secured ladder system to access different underground levels. This engineering infrastructure demonstrates the significant effort required to make the cave's depths accessible to the public.
