Trail de la Mandallaz 

12 April 2026

Trail de la Mandallaz - A summit of sensations above Lake Annecy

Just a few kilometres from the hustle and bustle of Annecy, the Mandallaz mountain offers an exceptional natural setting for trail enthusiasts. Every spring, the Trail de la Mandallaz transforms La Balme-de-Sillingy into a sporting village, with a friendly atmosphere, challenging but fun routes and breathtaking panoramas. With breathtaking views over Lake Annecy, forest balconies, playful singles and rolling forest tracks, it's a concentrate of pleasure with every stride.


The routes

  • Trail à Deux Têtes - 21.4 km / 1070 m D+ (altitude gain)
    A beautiful mountain race alternating sharp climbs, technical trails and rhythmic descents. The passage over the Tête de la Mandallaz and then the Goliettaz plateau offers a variety of terrain and total immersion in Savoyard nature.

  • Trail à Une Tête - 11.1 km / 560 m D+ (over 560 m)
