The mouse cave is a Milly classic that all children know. It is a large cavity about 20 meters long, where you cannot stand up. It is even possible to exit through a narrow passage.

Small cave in the woods, with engravings, in homage to Samuel Adam-Salomon - French sculptor of the 19th Century who spent most of his life in Fontainebleau. His works are mainly exhibited at the Musée d'Orsay, the Invalides and the Chateau de Versailles.

The cave of the oath is quite surprising, especially because the vault is made of a single rock. The letters D.F.D were engraved on the cave by Denecourt himself and mean "Last Madness Denecourt".

La Caverne des Brigands was dug at Denecourt's request in 1844, in order to attract tourists! He then invents a story of brigands from scratch to arouse the curiosity of visitors.
