"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.”
