This period offers the most favorable weather conditions and full access to the higher trails. Always check local weather forecasts before you go.
No specific permits or entrance fees are required to mountain bike the Mont Lachat de Châtillon Loop itself. However, if you choose to use the Lachat chairlift or Rosay gondola for access, there will be a fee for their use. The Massif de Tournette-Aravis is a natural area, not a national park with strict entrance fees.
The terrain is varied, starting with paved sections that transition into primarily gravel roads after the Restaurant de la Croix. As you ascend, you'll encounter very steep gravel sections, potentially requiring you to dismount and push your bike. The route also includes a 'fun descent' towards Chinaillon and beautiful trails winding along the mountainside.
You'll be treated to exceptional 360° panoramic views from the summit of Mont Lachat, including the Jura, Bauges, Chablais, Bornes, Aravis, and Bargy mountain ranges, as well as Mont Blanc. An orientation table at the top helps identify these peaks. Other highlights include the View of the Aravis Mountains and the Col des Annes. You'll also see the Thônes Valley, lush alpine meadows, and a scenic lake during a descent from Colombière.
