Mackó Cave, also known as Kis-kevélyi-barlang, is one of the most famous and strictly protected caves in the Pilis Mountains. Its massive, arched entrance — over 11 metres wide and more than 5 metres high — is impressive from a distance and has drawn hikers for generations.

The cave lies on the northern slope of Kis-Kevély, right next to a marked hiking trail, in a forest close to the summit. It is a former, now inactive spring cave, formed in Triassic Dachstein limestone. Inside there is little dripstone decoration — just a few small stalactites — but the atmosphere is striking, with a large chamber narrowing inward and a chimney reaching toward the surface. The surrounding rocks also offer nice views over Csobánka and its surroundings.

How to get there

• Csobánka (village centre) — yellow trail, the easiest and most popular approach, moderate terrain
• From the Kevély-nyereg mountain hut — descend via the yellow trail heading towards Pilisborosjenő

Practical information

• The cave is strictly protected due to valuable archaeological and paleontological finds
• The entrance chamber can be freely visited in ordinary clothes, without equipment
• Exploring the inner sections requires basic caving gear and a light source

Bones of cave bears, hyenas, woolly rhinoceroses and reindeer, along with tools left by prehistoric humans, were unearthed here — discoveries that made the cave internationally known among archaeologists.
