 age. The caves were formed by a small stream at the end of the Terciary period, as well as by the rainfall that seeped through cracks in the limestone.

A tour leads the visitors through the upper and middle levels, presenting a chain of domed chambers, caves and passages with dark abysses between them. The most beautiful area is deemed by experts to be the extensive Prošek chamber with its sinter Jezírko lásky (Little lake of love).
