"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.
A show cave is defined as a natural occurring void beneath the surface of the earth that has been made accessible to the public for tours.
The International Show Caves Association (ISCA) invites show caves, organizations, and visitors worldwide to celebrate the 10th anniversary of the International Day of Caves and the Subterranean World on June 6, 2026, through educational activities, public events, promotional campaigns, and initiatives aimed at raising awareness about the value and protection of subterranean heritage.
