Tourists who decide to explore Plavecký Kras, a nature area at the edge of the Bratislava region, can enter a freely-accessible cave but also experience a scene resembling that of the Dalmatia region and Biokovo mountain in Croatia.

Access is via the Plavecký Kras educative path.
When exploring the path from the village of Plavecký Mikuláš, Deravá Skala (Holey rock) Cave is the first stop.
Alexander Lačný of the Administration of the Malé Karpaty Protected Area said that in Plavecký Kras, one of eight karst areas in the area of the Malé Karpaty (Small Carpathians) there are about 150 caves.
