Pic Saint-Michel
🏔️ Overview
Pic Saint-Michel is a prominent limestone summit rising to 1,966 meters (6,450 feet) in the Vercors Massif of southeastern France. Located in the Isère department of Auvergne-Rhône-Alpes, the mountain forms part of the dramatic eastern rim of the Vercors overlooking the Grenoble region.
Although modest in elevation compared with the great glaciated summits farther east in the Alps, Pic Saint-Michel occupies an exceptional position. Its eastern side falls away in steep limestone cliffs, while its western slopes descend more gradually toward the high plateau and Lans-en-Vercors.
The mountain is especially popular with hikers because its summit can be reached without technical climbing in normal summer conditions. The reward is a wide panorama encompassing the Vercors, Grenoble basin, Belledonne, Chartreuse, and numerous higher Alpine ranges.

📍 Location
Pic Saint-Michel stands on the northeastern side of the Vercors Massif, southwest of Grenoble and immediately east of Lans-en-Vercors.
The summit belongs to a long north–south limestone crest forming the eastern edge of the Vercors. This ridge extends through a succession of summits, cliffs, cols, and rocky highlands overlooking the deep valleys around Grenoble.
Grand Cheval lies to the north of Pic Saint-Michel, while Col de l’Arc separates it from higher terrain to the south. Continuing along the crest eventually leads toward Crête des Crocs, Rochers de l’Ours, Roc Cornafion, and other summits of the eastern Vercors.
The mountain’s geography creates two very different landscapes. To the west, relatively gentle slopes descend toward the broad Val de Lans. To the east, the mountain ends abruptly in imposing limestone cliffs overlooking the valleys below.
📏 Elevation & Prominence
Pic Saint-Michel reaches 1,966 meters (6,450 feet) above sea level.
Its topographic prominence is approximately 233 meters (764 feet), making it a clearly defined summit rather than simply a minor point along the eastern Vercors ridge.
The mountain’s isolation is approximately 1.6 kilometers (1 mile).
Its nearest higher neighbor is Crête des Crocs, approximately 1.6 kilometers southwest of the summit. PeakVisor lists Crête des Crocs at approximately 1,980 meters (6,496 feet).
This NHN is worth noting because several other nearby Vercors mountains are more famous or substantially higher, but Crête des Crocs is the first higher terrain encountered when measuring Pic Saint-Michel’s topographic isolation.
The broader topographic parent given by PeakVisor is Grand Veymont, the dominant summit farther south in the Vercors.
🪨 Geology
Pic Saint-Michel is a classic example of the limestone geology that defines much of the Vercors Massif.
The summit ridge consists predominantly of Urgonian limestone, a thick formation dating from the Early Cretaceous. These limestones originated as marine sediments deposited in warm, relatively shallow seas long before the modern Alps existed.
During the formation of the Alps, tectonic compression folded, faulted, and uplifted these sedimentary layers.
Erosion subsequently shaped them into the cliffs, plateaus, ridges, gorges, and karst landscapes for which the Vercors is famous.
Pic Saint-Michel has the form of a crêt, or asymmetric ridge produced by tilted resistant rock layers. Its western side follows the comparatively gentle dip of the limestone beds, while its eastern edge terminates in cliffs exceeding 200 meters in places.
Weathering of the limestone has also produced areas of lapiaz—exposed limestone surfaces dissected by cracks, grooves, and solution channels created as slightly acidic rainwater gradually dissolves the rock.
This terrain is one of the characteristic features hikers encounter on the summit route.
🌿 Flora & Fauna
Pic Saint-Michel lies within the Parc naturel régional du Vercors, an exceptionally diverse protected mountain landscape.
Lower slopes support forests dominated by species adapted to the cool, relatively moist climate of the northern Vercors. As elevation increases, forests give way to mountain grasslands, rocky pastures, limestone outcrops, and alpine vegetation.
Plants growing on the exposed summit ridge must tolerate wind, thin soils, summer drought, snow, and rapid temperature changes.
The wider Vercors provides habitat for many characteristic Alpine animals, including:
- Chamois
- Alpine ibex
- Marmots
- Roe deer
- Golden eagles
- Griffon vultures
- Bearded vultures
- Numerous smaller mountain birds
Golden eagle sensitivity areas occur along the Pic Saint-Michel hiking route, and visitors should respect seasonal conservation guidance and remain on established trails.
Livestock also graze some of the Vercors high pastures during summer. Hikers may therefore encounter Patou livestock guardian dogs protecting sheep.
🥾 Hiking & Climbing Routes
Pic Saint-Michel is primarily a hiking mountain rather than a technical climbing objective during normal snow-free conditions.
One of the best-known routes is the Pic Saint-Michel and Col de l’Arc circuit, promoted by the Vercors Regional Nature Park.
The official route is approximately:
- Distance: 9.8 km / 6.1 miles
- Elevation gain: approximately 706 m / 2,316 ft
- Time: about 4 hours 30 minutes
- Route type: Loop
The hike begins from the Les Barnets parking area on the Route des Montagnes de Lans near Lans-en-Vercors.
The trail climbs through wooded terrain before emerging into increasingly open mountain country. Higher up, hikers cross limestone terrain and alpine pastures before reaching Pic Saint-Michel.
From the summit, the route can continue south along the crest toward Col de l’Arc before descending back toward the western side of the mountain.
Although the hike does not normally involve technical climbing, it should still be treated as a mountain outing. Wet limestone can become extremely slippery, and cloud, thunderstorms, snow, strong winds, and sudden temperature changes can transform conditions quickly.
🏔️ Field Guide Tip: The eastern side of Pic Saint-Michel contains major cliffs. Stay on marked trails near the summit and do not approach cliff edges in fog, strong wind, snow, or poor visibility. Carry an offline map and enough clothing for conditions significantly colder than those in Grenoble or Lans-en-Vercors.
🌤️ Best Time to Visit
June through October generally provides the most practical hiking conditions on Pic Saint-Michel, although snow conditions vary significantly from year to year.
July and August offer long daylight hours and usually snow-free trails, but thunderstorms can develop rapidly during warm summer afternoons.
June can provide beautiful wildflowers and quieter trails, though late snow may remain after snowy winters.
September and early October are particularly attractive when stable weather combines with cooler temperatures and autumn colors in the forests below.
Winter completely changes the character of the mountain. Snow can obscure trails, cornices may form near exposed ridges, and avalanche conditions may affect some slopes. Winter trips require appropriate equipment, navigation ability, and experience assessing mountain snow conditions.
🧭 Nearby Mountains & Attractions
Moucherotte rises north of Pic Saint-Michel and forms another famous viewpoint above Grenoble. Together, the two mountains help define the northeastern skyline of the Vercors.
South of Pic Saint-Michel, the eastern crest continues toward higher and increasingly rugged terrain. Crête des Crocs, its nearest higher neighbor, rises only about 1.6 kilometers away.
Farther south lies Grand Veymont, one of the defining summits of the Vercors and the topographic parent associated with Pic Saint-Michel.
The village of Lans-en-Vercors provides one of the principal gateways to the mountain and to the northern Vercors.
Across the Grenoble region, the Vercors faces several other major Alpine massifs. The higher crystalline mountains east and southeast of Grenoble include the Taillefer area, where Le Taillefer rises to 2,857 meters.
Nearby Mountain Field Guide destinations in Isère also include La Pyramide d’Ornon and Pointe de Malhaubert.
