Grotte des Planches, Show cave in Les Planches-près-Arbois, France.
The cave system extends over 8 kilometers through limestone formations, featuring multiple galleries with distinct geological characteristics and mineral deposits.
Discovered in 1813, the cave underwent scientific exploration in 1904 by geologist Maurice Piroutet, revealing artifacts from the Upper Paleolithic to Bronze Age periods.
The cave holds archaeological evidence of human settlements, with stone tools and burial sites uncovered during excavations throughout different cave sections.
The interior temperature remains constant at 12°C for air and 6°C for water, requiring visitors to bring appropriate clothing for the cool environment.
The cave contains four distinct galleries, with the lower gallery feeding the Cuisance River and upper sections containing gypsum crystal formations.
