The Guesot bottom caves in Fontenoy are part of a natural site which includes the slopes of Port-Fontenoy and the Ru de Vaux valley. The caves are home to rare bats that hibernate there in winter, and also contain prehistoric carvings on the walls. The caves are not open to the public, so you will need to obtain special permission from the Conservatoire des Sites Naturels de Picardie before you can visit them.

The caves are not open to the public, so you will need to obtain special permission from the Conservatory of Natural Sites of Picardy before you can visit them. On the other hand, you can admire them from the outside while running.
