Europe's cave systems range from the decorated prehistoric caves of the southwest and the vast karst networks of the central mountain zones to the lava tubes of the Atlantic islands and the ice caves of the northern volcanic regions. The continent contains some of the world's most significant cave environments both geologically and archaeologically, with prehistoric art, exceptional formations and underground river systems distributed across a well-developed show cave infrastructure.
The prehistoric decorated caves of the southwest represent a category of experience unlike any other, with original Palaeolithic art in natural cave settings accessible at a small number of sites under strictly controlled visiting conditions. The continent's karst cave systems offer a parallel experience built around extraordinary stalactite and stalagmite formations, with show cave infrastructure of considerable quality across several countries supporting accessible visits without specialist equipment.
Access to the most significant prehistoric sites is strictly limited and advance booking is essential, with some sites requiring reservations months ahead. Seasonal flooding affects access at many karst cave systems and checking current conditions before travel is advisable. Adventure caving programmes are available across the continent's most developed karst regions for visitors seeking experiences beyond standard show cave formats.
