Guidebook with maps/step-by-step
1. Turn away from the church, take the small road that weaves between the farms on your left and cross the hamlet of Le Vernay (orchards). Take the D15 to the right for 50 m, then climb left along the grassy path through the pastures, past the oratory (sand outcrops typical of the subsoil on this slope).
After several forks (follow the signs) in the undergrowth, reach a crossroads (signpost; 1,000 m).
2. Continue uphill towards the Plan bend. The path climbs a steep slope and enters overgrown alpine meadows. Reach the "Roc du Château" signpost.
3. Climb to the left and reach the "virage du Plan" on the D41 (open view of Les Bornes, orientation table, picnic area).
You can continue uphill to the Salève Plan viewpoint (25 min).
4. Return to the Roc-du-Château crossroads.
5. Follow signs to the left for "Vovray par Rogin". First stay level in the alpine pasture, then descend through the beech forest on the wide, winding path. It passes over slabs (slippery in wet weather: take care) and meets numerous junctions (follow the signs). As you approach Rogin, the slope steepens in the coniferous forest.
