Caves are known to man for ten thousands of years. The history of the first cave visits is written on the walls of prehistoric painted caves. But later in history people became angry and fearful about caves. They were thought to be the entrance to hades, the hell, the home of trolls or other fabulous fairy tale creatures. In this times many caves were dubbed Devils Hole, Unicorn Cave or something similar. And mostly people were too afraid to visit them.
But there are some extraordinary exceptions, which we tried to collect. This is a list of early developments in cave tourism, what later became show caves or commercial caves. It is far from being complete, but we hope we added the most important milestones.
