The discovery was made by widening a narrow opening known as a 'sinkhole' that emitted cold air.
The cave is formed in Mesozoic limestones of the Orešany unit.
Some chambers, such as the Beňovského Hall, were named after local historical figures.
The cave contains a specific type of thin, fragile stalactite formations called 'straws'.
It serves as an important wintering site for several species of bats, including the greater horseshoe bat.
The cave’s narrow passages are a result of tectonic movements rather than wide underground river flows.
It is the only cave in the western part of Slovakia open to the general public.
Driny is the only accessible show cave in the Little Carpathians mountain range of western Slovakia. The karst system is characterized by narrow, fissure-like corridors and significant sinter decorations including dripstone waterfalls, pagodas, and curtains. The cave system was discovered in 1929 through a narrow hole in the ground by local residents Ján Banič and Imrich Vajarský. It spans a total length of approximately 680 meters, with a designated tourist trail covering about 450 meters. The cave remains a protected natural monument managed by the Slovak Caves Administration. Constant temperature inside the cave typically ranges between 7.1 and 7.8 degrees Celsius throughout the year. The formation of the cave occurred due to the corrosion of limestone within the Pezinok Carpathians block.

Wear a warm jacket regardless of the outside temperature, as the cave is cold and damp.
Use sturdy, non-slip footwear as the ground inside can be wet and uneven.
Check the official cave administration website before traveling, as it may close during severe weather or maintenance.
Attempting to visit during the off-season without checking the schedule, as the cave is not open year-round.
Closed on Mondays and throughout the winter months; seasonal operations typically run from spring through late autumn.
