Hike connecting Igny (Essonne) to the Palace of Versailles. The route follows the Bievre, and 80% of the route is on roads through forests. A calm, cool walk with scenery that will leave you with a unique souvenir.

A beautiful hike to discover the beautiful sights of the Chevreuse valley: the Chatillonmill, the castle of Dampierre, the blacksmith’s, the villages of Fourcherolles, Senlisse and Choisel, Méridon castle, the village of Chevreuse and its small bridges along the Yvette, and Château de la Madeleine.

Le Quartier Latin is a labyrinth of streets, each as important as the next, as there is a strong history behind. The Sainte-Geneviève Mountain is home to several prestigious schools, and the presence of numerous students adds to the atmosphere of this magnificent suburb.

An urban circular walk in search of the French Revolution routes in two Parisian sites: the Bastille, whose capture had a very strong symbolic impact, and the Odéon suburb, where several key figures of the period lived, worked and gathered, including Marat and Danton.
