The Grand Crêt, at an altitude of 1,702 m, offers a magnificent view of the entire Alps, dominated by Mont Blanc. With a good pair of binoculars, in good weather, and unless I'm mistaken, the Matterhorn (4,478 m) in Switzerland is visible!

Fantastic view - fantastic path. I was there for the first time in October 1976.

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.

The natural monuments around Sergy are accessible in all seasons, offering different experiences. Spring and summer are ideal for hiking and enjoying the diverse flora, including mountain flowers.

The Haute Chaîne du Jura National Nature Reserve offers various trails, and some routes to viewpoints might be more accessible. It's recommended to check specific route details for distance and elevation gain to ensure they are suitable for all family members.
From the summits of natural monuments like Crêt de la Neige, Le Reculet Summit, and Grand Montrond, you can expect spectacular 360-degree panoramic views. On clear days, these include Lake Geneva, the Valserine Valley, La Dôle, the majestic Alps (including Mont Blanc), and sometimes even the Vosges mountains and the Black Forest.
While the highest peaks are well-known, the broader Haute Chaîne du Jura National Nature Reserve contains numerous less-trafficked areas. Exploring the diverse geological formations, such as the karstic features and varied forest ecosystems, away from the main summits can reveal unique and tranquil natural spots. The Grand Crêt, for instance, offers stunning views and is slightly less frequented than its neighbor, Crêt de la Neige.
Given the varied terrain and altitudes, it's advisable to pack layers of clothing suitable for changing weather conditions. Sturdy hiking boots are essential. Depending on the season, consider bringing sun protection, rain gear, sufficient water and snacks, and navigation tools. For winter visits, snowshoes and appropriate cold-weather gear are necessary.
The duration of hikes to major natural monuments varies significantly based on the starting point and your fitness level. For example, a hike to Crêt de la Neige or Le Reculet Summit can range from 3 to 6 hours or more for a round trip, depending on the chosen route. Shorter, easier walks are also available in the lower parts of the reserve.
While Sergy itself has some local transport, direct public transport to the trailheads of the higher natural monuments can be limited. Many visitors opt for personal vehicles to reach parking areas closer to the starting points of popular hikes. It's recommended to check local bus schedules or consider carpooling for access to more remote natural sites.
