Mont Buet Loop

The Mont Buet Loop typically starts from Le Buet, a small hamlet near Vallorcine. Parking is usually available at or near the trailhead in Le Buet. It's advisable to arrive early, especially during peak season, as parking can fill up quickly.

While dogs are generally allowed on trails in the region, the Mont Buet Loop is located within the Aiguilles Rouges Nature Reserve. Regulations within nature reserves often require dogs to be kept on a leash to protect wildlife. Given the challenging and exposed terrain, including sections with cables and steep drops, this trail might not be suitable for all dogs, especially those not accustomed to alpine conditions. Always check local regulations before you go.

The best time to tackle this loop is typically from mid-July to early September. Snowfields can linger on the route well into summer, and early season (late June to mid-July) may still require crampons for hard snow patches on the ridge. Always check current trail conditions and weather forecasts before heading out.

No specific permits or entrance fees are required to jog the Mont Buet Loop or to enter the Aiguilles Rouges Nature Reserve. However, as with any protected area, it's crucial to respect the natural environment by staying on marked paths, not disturbing wildlife, and carrying out all your waste.

The terrain is highly varied and demanding. You'll start with gradual climbs through forest trails and meadows, transitioning to increasingly technical and rugged sections with rocky surfaces, granite slabs, and scree. Expect steep ascents, some requiring the use of cables and metal steps, particularly on the ridge leading to Le Cheval Blanc Summit and the final push to Mont Buet. The descent on the south side of Buet is known for being particularly poor for running, characterized by loose, round, and unstable ground.

This loop is renowned for its breathtaking panoramic views. From the summit of Mont Buet, you'll get 360-degree vistas of the entire Alps, including the Mont Blanc Massif, the Matterhorn, Switzerland, and Italy. Other highlights include Le Cheval Blanc Summit, beautiful valleys, granite basin lakes, and the Cascade de Bérard waterfall. You'll also pass by the Loriaz Refuge.

Yes, water sources are available at refuges along the route, such as the Loriaz Refuge. However, it's always wise to carry sufficient water for your entire journey, especially on challenging routes like this, and to refill whenever possible.

Given the trail's difficulty and varied terrain, you should bring sturdy trail running shoes with good grip, appropriate layers for rapidly changing alpine weather, a waterproof jacket, sufficient water and snacks, a headlamp, a first-aid kit, and a map or GPS device. For early season or if snow is present, crampons might be necessary. Poles can also be very helpful, especially on the steep and loose descents.

Yes, the route intersects with several other trails. Notable sections include parts of the Mont Buet trail (43% of the route), Tour de la Vallée du Trient (22%), and Chalet de Loriaz (17%). You may also encounter sections of the Tour Du Mont Blanc - Variante de Vallorcine and the Traces des dinosaures-Col de la Terrasse.

Beyond the significant elevation gain and loss (over 2000 meters), the challenge lies in the highly technical and exposed sections. These include rocky ridges with big drops, requiring hand and footwork, and passages facilitated by cables and metal steps. The north ridge of Mont Buet is particularly vertiginous. Additionally, the descent on the south side is notoriously difficult for running due to loose, unstable ground, demanding constant attention and sure-footedness.

Many experienced trail runners suggest approaching the Mont Buet Loop with a mindset of hiking the most technical and exposed sections, particularly the final ascent to Mont Buet and the entire descent on the south side. The descent is described as exceptionally poor for running due to loose, round, and unstable ground, making a controlled hike a safer and often faster option than attempting to run it. Focus on enjoying the spectacular views during the runnable sections and exercising caution where the terrain demands it.
