Show cave
Encyclopedia
Show caves — also called tourist caves, public caves, and in the United States, commercial caves — are cave
s that are managed by a government or commercial organization and made accessible to the general public, usually for an entrance fee. Unlike wild caves, they typically possess such features as constructed trails, guided tours, lighting, and regular opening hours.
"Show cave" has inconsistent usage between nations, with many countries tending to call all caves which are open to the public show caves. However there are many caves which are not developed (no trails, no light, no tours) but are visited by very many people. This kind of cave is often called a semi-wild cave. Access may involve anything between an easy stroll and dangerous climbing. Most cave accidents happen in this kind of cave, as visitors often underestimate the difficulties and dangers.
