Mont Narcel, Mountain summit in Metropolis of Lyon, France

Mont Narcel is a summit of the Monts d'Or, reaching 589 metres on the boundary between Limonest and Saint-Didier-au-Mont-d'Or, less than a kilometre from Mont Thou. Its slopes, notably those of Les Essarts, carry rare orchid species, and two springs, Sanlaville and La Barollière, still flow on the Limonest side. A Chappe telegraph tower stands at the top.

The name Narcel is thought to derive from the Latin arca, a word the Romans used for chests, referring to the underground passages that capture or carry water on the mountain. Two springs still exist on the Limonest side, Sanlaville and La Barollière. The summit also holds an old Chappe telegraph tower.

Local residents have built and maintained traditional dry stone structures called cabornes on the slopes, showing how people have lived with the mountain for generations. These small buildings reflect how locals adapted their building methods to the steep terrain.

Multiple marked hiking trails connect to Lyon nearby and suit different fitness levels for visitors. Most routes are walkable year-round and well marked throughout the mountain.

The tower at the summit is a relic of the Chappe optical telegraph line, a network of relay stations that carried coded signals across France before electric telegraphy. On the Essarts slope, more than a hundred dry-stone cabornes once stood; remnants of these small shelters can still be found among the rocks.
