Enter a fascinating underground world!
Lot-et-Garonne has just two natural caves: the Lastournelle cave in Sainte-Colombe-de-Villeneuve and the Fontirou caves in Castella.
But do you really know how caves work? Natural caves are underground cavities formed over thousands of years by geological processes. They are found in almost every region of the world and are one of nature’s most fascinating spectacles.
The interior is often decorated with stalactites (hanging from the “ceiling”) and stalagmites (rising from the floor), formed by the slow accumulation of minerals contained in the water. Caves also provide a unique habitat for species adapted to the dark, such as bats, blind insects and certain species of fish.
