Wonderful place! Great view! The climb is tough and depending on the route you have to push your bike. I chose the climb via La Barillette and had to walk for about 30-45 minutes. There was also a bit of snow which meant a bit more walking.

attention ! only the return trip by the same path is possible between Petit Montrond and Grand Montrond from June 1 to September 30. the loop passing through private mountain pastures is closed between these dates. no particular difficulty except for a few rocky passages and a slight difference in altitude. a pair of shoes with a stiff, grippy sole can help, but it's also doable in sneakers, as long as you're used to mountain paths.

This trail runs along an alpine pasture where Patous are present: The Patou or protection dog: What attitude should you adopt? When hiking, it is common to come across flocks of sheep or goats guarded by protection dogs, called Patous. These dogs, formidable against predators such as wolves, bears and lynx, can frighten hikers with their barking. The Patou protects the flocks in total autonomy. Its main role is to dissuade intruders and alert the shepherd. Raised among the sheep from a young age, it learns to protect them permanently, often in groups. To avoid problems with a Patou: - Identify the pasture areas before leaving. Keep your distance and go around the flocks if possible. - In the event of an encounter, remain calm, turn around slowly or stop to let the dog sniff you. - Do not try to pet or feed the animals, avoid sudden movements, do not run, and avoid taking pictures. For trail runners: - Do not run when approaching a herd. - Take off your headphones to hear the dog barking. By adopting these behaviors, you will be able to coexist peacefully with the protection dogs during your hikes.
