"Our world’s caves are places of wonder, mystery and majestic beauty. Show caves around the world are embracing their role in protecting and preserving caves and providing a place for people to learn about these special, natural, cultural and historical resources.

Show caves also play another important nature tourism role of sustainable economic development, providing jobs, and helping the economy of their regions.”


The International Show Caves Association (I.S.C.A.) was founded in November 1990 and set up its central office in Genga, Italy. After the first Consitutent Assembly held in Frasassi (Genga Ancona, Italy) in November 1989, important events have contributed to the development and consolidation of the association.
