Beautiful, technical, wild, demanding, there are not enough adjectives to describe the TDS. Acronym for “Sur les Traces des Ducs de Savoie” (following the footprints of the Dukes of Savoie), the TDS links the Aosta Valley to the Savoie, allowing you to discover the villages of the Tour du Mont-Blanc and the mountains that surround them. To cross this unique playground is to walk where history and mountains, the technical terrain and the kindness of its inhabitants blend together.
