Réserve naturelle de Sas-hegy

Sas-hegy Reserve is a 30-hectare protected area at 266 meters elevation featuring dolomite grasslands with steep rocky surfaces on its southern and eastern sides. The hillside is distinguished by its limestone formations that create a rare landscape within the urban environment.

The area received official protection status in 1957 through Resolution 985/1957 by the National Nature Conservation Council, establishing strict preservation guidelines. This designation made it one of the earliest examples of systematic nature conservation in Budapest.

The visitor center hosts an interactive exhibition titled 'Shelter in the Concrete Jungle' that teaches guests about the local wildlife and conservation work happening here. This display helps people appreciate why this natural space matters for the city.

The reserve welcomes visitors from March through November on Wednesday to Sunday between 10 AM and 6 PM, with guided tours available by prior registration. Planning ahead for a tour helps you get more out of your visit.

An underground seismic observatory built originally as a military tunnel during World War II has monitored earth movements near Sas-hegy since 1966. This hidden structure blends wartime history with modern scientific purpose.
