This peak is a must-see for its unique views of the Valserine valley, the Jura and Mont-Blanc. After a climb through the forest, a flight of steps will complete the hike for a contemplative reward!
This hike, which can be enjoyed from April to November, starts from Forens. A path leads through the woods to the ruins of a house called the “Grand Mannet”. The view gradually opens up over the Valserine valley and the Haute Chaîne du Jura. The last few metres are up a steep path, followed by steps to the summit. From here, a 360° panorama of the Mont-Blanc which appears so close to the Jura mountains and the folds of the Jura massif. then to, note the “Borne au Lion”, the 17th-century border marker between Franche-Comté, Bugey and the territory of the Duchy of Savoy. Explanatory panels tell the story of the resistants who hid here during the Second World War. To round off the hike, a short detour to the lovely Étrès waterfall is a must.

▶ Before setting off :
Check the general and local weather forecast, and make sure there's no precipitation.
Find out about the approach route, the height of the itinerary, the time it will take to complete the climb, and any possible escapes (IGN map, GPS, topo-guide, etc.).
Evaluate possible risks by asking mountain professionals, mountain huts and gîtes.
Inform someone close to you of your objective, and contact them again in the event of any changes: departure and return times, number of participants with telephone numbers for each, vehicle(s), parking, etc.
Avoid setting off alone, and use equipment that is suitable for the activity, adjusted and in good condition: headlamp, complete first-aid kit, survival blanket, etc.
In the event of a problem, call 112 (European emergency number).
(1) Start at the Forens washhouse on the RD 14. From the very first steps, the path rises gently winding under the canopy of trees skirting a peaceful stream. Gradually, the slope becomes steeper inviting you to start climbing.
(2) From this house the white path gives way to a narrower path that gently winds into the forest between the trees.
(3) The route passes an old spring and a ruin still clearly visible, vestiges of another era. It then climbs along a shady ridge, where the light filters through the foliage.
(4) After several hundred meters of ascent through the forest, the vegetation gradually opens up, revealing a small valley with a panoramic view of the surrounding area. Continue straight ahead at the intersection.
Yes. Accepted but on a leash.
