The Frasassi Caves are a vast complex of karst caves located in the Marche region, in the province of Ancona; they are considered the most spectacular caves in Italy and Europe thanks to their size and abundance of limestone formations.
The Frasassi Cves extends over 35km of underground galleries and caverns. The tour allows the visits of only two caves: the Grotta Grande del Vento and and the Grotta del Fiume. The Grotta Grande del Vento is the most spectacular with enormous chambers that exceed 100 meters in height and 200 meters in width: the walls and vaults are covered with stalactites, stalagmites, columns and formations of the most unique and imaginative shapes.
The karst complex formed over approximately one million years, due to the effect of rainwater that eroded and shaped the limestone rock of karst nature: the waters, infiltrating the underground, created canyons, lakes and waterfalls of rare beauty. In the caves, it is possible to admire the remains of Ursus spelaeus, the cave bear which lived up to 25.000 years ago.
The Frasassi Caves are a wonder of nature that leaves vevery visitor speachless: the vastness of the underground chambers and the myriad of formations with the most bizarre shapes sculpted during the centuries are a surreal and incredibly beautiful visual spectacle. It is a must-visit destination for those seeking to discover the natural beauty of the Marche region.
