Call for volunteers! The French General Staff is recruiting spies to unlock the secrets of the fortress and free the imprisoned lieutenant colonel.
New scenario of the family treasure hunt in the Esseillon forts.


A walk to share with family or friends, the Savoyard Discovery Walk of the Esseillon Forts will allow you to understand the heritage in a playful way.
This year, Aussois offers you a new scenario plunging you in 1840, through the mazes of the imposing fortress where spies are swarming.
Call for volunteer French soldiers! Infiltrate the enemy fort Victor-Emmanuel to shed light on its organization and the life of the Sardinian garrison. Collect your logbook to get into the fort and solve the riddles that will also allow you to free Lieutenant Colonel Desgranges. The giant leaves scattered along the route will bring you the information obtained and transmitted to the French headquarters by the lieutenant-colonel before he was imprisoned.

Each visitor will discover something new:
- Spies' trail: follow the signs
Duration : about 2h30
Height difference: 100 meters (stairs)
- Comfort walk: part of the fort accessible to all, without games (families with strollers, seniors, accompanied persons with reduced mobility).
