Jaskinia Raj

Jaskinia Raj is a show cave in the Holy Cross Mountains of Poland that extends horizontally through several connected passages. The three main corridors meet near the entrance, where artificial sections provide access for visitors.

Two students discovered the cave in 1964 during a geological trip through the region. After eight years of geological study and construction work, it opened to the public.

The name comes from the dense arrangement of dripstone formations overhead, which early explorers compared to a heavenly vault. Today the space is visited mostly by hikers passing through the Holy Cross Mountains who seek natural landmarks along their routes.

Tours last about an hour and cover roughly 150 meters of underground path, with small groups entering one after another. The floor is uneven and damp in places, so visitors should wear sturdy footwear.

In some sections over 200 stalactites hang from each square meter of ceiling, making this one of the highest densities recorded anywhere. The cave sheltered Neanderthals around 50,000 years ago, and tools and bones of animals like cave bears and woolly rhinoceros still appear in its deposits.
