Le Tabor
Le Tabor, also known as Tabor de la Matheysine, is a prominent mountain in the Isère department of southeastern France. Rising to 2,389 meters (7,838 feet), it forms the highest point of the central chain of the Taillefer Massif and overlooks the Matheysine plateau south of Grenoble. Although considerably lower than the highest summits of the French Alps, Le Tabor is remarkably prominent and offers expansive views over the surrounding Alpine ranges.
Its combination of open ridges, alpine meadows, rocky upper slopes, and relatively straightforward hiking access makes Le Tabor a rewarding objective for experienced hikers exploring this quieter part of the Dauphiné Alps.
🏔️ Overview
Le Tabor stands on the western side of the Taillefer Massif, a compact mountain group in the French Alps between the Matheysine plateau and the higher mountains of the Oisans.
The massif is divided into several roughly north-south chains. Le Tabor reaches 2,389 meters and is the highest summit of the central chain, which also contains the Grand Serre, Pérollier, Grand Vent, Oreille du Loup, and Piquet de Nantes. The much higher eastern chain contains mountains such as Le Taillefer and Grand Armet.
Le Tabor’s elevation is moderate by Alpine standards, but its considerable topographic prominence gives it a commanding appearance above the Matheysine landscape.

Elevation sources commonly give 2,389 meters, while Peakbagger’s digital elevation data gives 2,390.7 meters. Peakbagger calculates approximately 1,020.8 meters of prominence and 5.09 kilometers of isolation.
* NHN note: Peakbagger’s elevation-ladder data places Grand Armet among the next higher named summits associated with Le Tabor. PeakVisor’s more detailed local mapping identifies a minor 2,480-meter summit called Rocher Rond, approximately 5.1 kilometers east-southeast, as the closest higher summit. For consistency with Mountain Field Guide’s Peakbagger-based NHN convention, Grand Armet is retained in the table, but the distinction is worth noting.
📍 Location
Le Tabor is situated in Isère, within France’s Auvergne-Rhône-Alpes region. Its summit lies east of the Matheysine plateau and roughly south-southeast of Grenoble.
The mountain rises between the Matheysine country to the west and the more rugged interior of the Taillefer Massif to the east. Its location makes it a particularly good viewpoint across the surrounding mountains.
To the north, the ridge continues toward Oreille du Loup, Grand Vent, and Pérollier. To the south lies Piquet de Nantes, a 2,214-meter summit that is frequently combined with Le Tabor in a longer ridge hike.
The communities of Saint-Honoré, Nantes-en-Ratier, and La Mure provide convenient gateways to the mountain.
📏 Elevation & Prominence
Le Tabor’s commonly accepted mapped elevation is 2,389 meters (7,838 feet). Peakbagger’s digital dataset records a slightly higher figure of approximately 2,390.7 meters.
What makes Le Tabor particularly significant is its prominence.
Peakbagger calculates approximately 1,020.8 meters (3,349 feet) of topographic prominence. That is an unusually large figure for a mountain of its height and places Le Tabor among the more prominent summits of the French Alps.
Its isolation is approximately 5.09 kilometers (3.16 miles).
These figures explain why Le Tabor appears so dominant when seen from the Matheysine plateau. It is not simply a minor shoulder of a larger mountain but a geographically distinct summit separated from higher terrain by substantial vertical relief.
🪨 Geology
Le Tabor belongs to a geologically complex portion of the western French Alps.
Much of the Taillefer Massif consists of old crystalline basement rocks. Geological mapping of the Tabor area shows crystalline formations associated with the southern Taillefer block, while the broader massif contains rocks including gneiss, amphibolite, schist, gabbro, and other metamorphic and igneous formations.
The geology reflects a history far older than the modern Alps themselves.
Ancient basement rocks were affected by repeated episodes of deformation before later Alpine mountain building uplifted the region. Faulting, folding, erosion, and Quaternary glaciation subsequently helped produce the ridges, valleys, rock outcrops, and broad high slopes visible today.
Le Tabor also sits close to an important geological transition between the crystalline Taillefer block and the sedimentary landscapes of the Matheysine region.
🌿 Flora & Fauna
The wider Taillefer region contains a mixture of alpine grasslands, heath, rocky habitats, wetlands, forests, and high-elevation meadows.
Parts of the massif are protected through the European Natura 2000 network. The designated Taillefer site protects thousands of hectares of heathlands, peatlands, rocky habitats, mountain lakes, and associated ecosystems.
Around Le Tabor itself, hikers travel through a transition from lower mountain vegetation into increasingly open alpine terrain. Summer brings grasses and flowering alpine plants to the high meadows, while the exposed summit ridge supports vegetation capable of surviving strong winds, snow cover, and a short growing season.
Wildlife found within the wider Alpine environment may include mountain mammals, birds of prey, and numerous smaller animals adapted to high elevations.
Visitors should avoid disturbing wildlife, picking flowers, or leaving waste. Conservation guidance for the Taillefer area specifically emphasizes keeping dogs controlled, avoiding fires, taking rubbish home, and minimizing disturbance to wildlife.
🥾 Hiking & Climbing Routes
Le Tabor is primarily a hiking mountain rather than a technical climbing objective during normal summer conditions.
From Saint-Honoré 1500
The classic approach begins at Saint-Honoré 1500, an abandoned former ski-development area above the village of Saint-Honoré.
A popular route heads toward Lac Charlet, then continues upward through open mountain terrain toward the main ridge. Once on the crest, hikers turn toward Le Tabor for the final approach to the summit.
Depending on the exact variation, a straightforward out-and-back or loop from Saint-Honoré typically involves roughly:
- Distance: around 9–12 km
- Elevation gain: approximately 900–1,000 m
- Time: roughly 5–7 hours
- Difficulty: moderate mountain hiking
Route statistics vary because several different loops and ridge combinations are possible.
Piquet de Nantes and Le Tabor Circuit
Another popular option combines Piquet de Nantes with Le Tabor.
Starting from Saint-Honoré 1500, hikers can climb onto the ridge, visit Piquet de Nantes, continue northward to Le Tabor, and then descend toward Lac Charlet.
One established circuit is approximately 12.6 kilometers with about 918 meters of ascent and normally takes around six hours.
The ridge walking is one of the highlights of the outing because it provides sustained views across the Matheysine and surrounding Alpine massifs.
Longer Tabor Massif Circuit
A much longer official hiking circuit explores more of the Tabor massif from Saint-Honoré. The tourism route covers approximately 19.5 kilometers, gains around 1,475 meters, and is estimated at more than eight hours.
This version is better suited to fit and experienced hikers comfortable with a long day in mountain terrain.
🏔️ Field Guide Tip: The Saint-Honoré route may look relatively gentle on a map, but Le Tabor still involves around 900 meters or more of climbing and prolonged exposure above the trees. Carry extra layers, water, sun protection, and reliable navigation, and check the mountain forecast before starting.
🌤️ Best Time to Visit
For hiking, the most dependable period is generally late June through September, once lingering snow has disappeared from the higher slopes.
July and August usually provide the longest daylight and easiest trail conditions, although afternoon thunderstorms can occur in the Alps.
September can be particularly rewarding, with cooler temperatures, clearer air, and fewer hikers. Shorter days and the possibility of early snowfall should be considered later in the month.
Snow can remain well into spring. Outside the normal summer hiking season, Le Tabor is also visited by ski tourers and snowshoers, but winter travel introduces avalanche hazards and requires appropriate experience and equipment. Local route descriptions document winter approaches from Saint-Honoré toward Lac Charlet and Le Tabor.
🧭 Nearby Mountains & Attractions
Two of the most significant neighboring mountains are Le Taillefer and Piquet de Nantes.
Le Taillefer rises to 2,857 meters and is the highest mountain of the Taillefer Massif. It belongs to the massif’s higher eastern chain and provides a very different hiking experience, with extensive rocky terrain and high mountain lakes.
Piquet de Nantes lies directly along the ridge south of Le Tabor. Because the two peaks can be linked in a single outing, it is one of the most natural additions for hikers who have enough time and energy.
