Go mountain biking around Crozet, where you will be rewarded with breathtaking panoramic views of Geneva and the Alps. As you ride, you will enjoy the mix of forest trails and open paths that offer great views of the surrounding landscape. Take time to admire the vast view that stretches from the city of Geneva to the majestic peaks of the Alps, passing by the serene waters of the lake.

Very nice hike. Perfect with 2 children and a dog. However, there is no sign indicating that we are entering a nature reserve, just a sign when we leave.

Starting point for the ascent to Reculet and/or Crêt de la Neige for motorized vehicles. The non-motorized and the courageous obviously leave from the village of Thoiry. In summer, the establishment sells drinks and pastries (when it is open).

Hidden gem. Cave hidden if you don't know about it. Tip: there is a little one on the other side further down, where you can get to a small hall going to a narrow passage :)
