Some of them were inhabited by humans as early as in the Neolithic Period; others provided shelter to various animal species that have long since gone extinct such as cave bears, mammoths and polar foxes; there are also caves which hide whole rivers and waterfalls deep inside them... But they have all acquired the same natural shape over the centuries!
While archaeologists forage caves to uncover natural history, speleologists are drawn by the cave formations which decorate the ceilings and walls of each one of them. Stalactites, stalagmites, cave columns, draperies and petrified waterfalls are just some of the formations shaped by water drops over the millennia and coloured by cave minerals in a myriad of colours and shades.
These unique natural decorations can only be found inside caves, so a tour provides a special opportunity to enjoy them.
