The Mandrin cave located in the town of Saint-Geoirs, in Isère, 30 km west of Voiron, is one of the many caves in France, especially in the Dauphiné and the Rhône valley, where it is called that the smuggler Louis Mandrin (1725-1755) would have hidden or would have stored the proceeds of his illegal activities.
It is a cavity actually dug by man, in an area located on the edge of the native town of Mandrin, Saint-Étienne-de-Saint-Geoirs, which at the time formed one and the same parish.
The cave is located on a fairly steep wall which dominates the RD 154 at the entrance to Saint-Geoirs, but fairly easy to access, near the Mas du Bottu. It is surrounded by a natural area renowned for the quality of its flora and fauna.
The site can be observed during a hike which will also include the birthplace of the bandit, in the center of Saint-Étienne-de-Saint-Geoirs: the building was built in 1515 and occupied from 1644 by the Mandrin family. His father, François, worked there as a trader.
In addition to the cave, the hike includes green areas of the Bièvre valley.
