Hohllay Cave

A natural limestone cave system famed for its spectacular stalactite and stalagmite formations as well as human artefact findings.

The limestone cave known as Hohllay Cave, often referred to as the Hohllay Grotto, is situated in the Luxembourgian village of Berdorf in the Mullerthal region. There are numerous connected chambers and corridors across the 300-metre-long cave system. The cave was formed over millions of years through the erosion of the soft limestone rock by underground streams. Stunning rock formations like stalactites, stalagmites, and columns were produced by the rushing water and can be viewed all throughout the cave. The cave also has a number of underground lakes and streams, which further enhance its natural beauty.

Guided tours that cover a distance of around 800 metres and last about 45 minutes are available for visitors to the cave. The excursions are given by knowledgeable instructors who share information about the geology, history, and different formations found inside the cave. Also, the guides point out fascinating details like the ‘Devil's Kitchen’, a sizable room with an unusual rock formation that mimics a stove.

The ‘Chamber of Wonders’, a sizable chamber with striking rock formations that have been lighted to emphasise their natural beauty, is one of the attractions of the Hohllay Cave. Concerts and other events are held in the chamber all year round.
