This route was planned by komoot.
This loop is categorized as difficult for trail running. While komoot lists it for jogging, the demanding terrain, significant elevation gain of over 1,300 meters, steep climbs, and rocky sections make it a strenuous endeavor best suited for experienced trail runners in good physical condition. It's not suitable for casual jogging.
The terrain is varied and often demanding. You'll encounter paths through forests and alpine meadows, but also significant rocky sections, some requiring the use of hands for stability. Portions are steep and stony, and there's a notable "passage aérien" (airy section) leading to the summit, as well as a path along a rock face.
The 2,181-meter summit of Mont Trélod offers exceptional 360-degree panoramic views, including iconic peaks like Mont Blanc, the Bornes, Aravis, Belledonne, and Vanoise massifs on clear days. Other notable points include Dent des Portes and the summit cross installed in 1937. You'll also pass by Col de Bornette.
As the trail lies within the protected Parc Naturel Régional du Massif des Bauges, you can experience a rich ecosystem. Expect diverse flora, including rare orchids and gentians, especially in the alpine meadows. Keep an eye out for wildlife such as chamois, particularly in higher, quieter sections.
Specific parking information for the Mont Trélod trailhead is not detailed in the provided sources. However, for trails of this nature in the Massif des Bauges, trailheads typically have designated parking areas, often small. It's advisable to check local maps or resources for the most precise parking locations before your visit, especially during peak season.
The recommended season for this trail is generally from June to October. During this period, conditions are typically most favorable, with less risk of snow and ice, making the challenging terrain more accessible. Outside of these months, especially in winter, there can be avalanche risk and wet waterfall sections, making the trail significantly more hazardous.
No, dogs are strictly prohibited on this trail. As the route is located within the Parc Naturel Régional du Massif des Bauges, which is a protected natural park, regulations are in place to preserve the local wildlife and ecosystem.
While the Mont Trélod loop is within the Parc Naturel Régional du Massif des Bauges, there are typically no specific permits or entrance fees required for hiking or trail running on the general trails within the park. However, it's always good practice to respect park regulations regarding wildlife, waste, and trail etiquette.
Yes, the route intersects with several other trails. You will find sections of the Mont Trélod trail itself, as well as parts of the Montagne du Charbon depuis Montgellaz, the GR 96, Pas de la Combe, and Sentier du Char.
Yes, there are a couple of huts along the route. You will pass by the Refuge de la Combe and Les Ailes du Nant. These can offer a place for a break or shelter, but it's always wise to check their operating status and services beforehand if you plan to rely on them.
Given the trail's difficult rating and varied terrain, essential gear includes sturdy trail running shoes with good grip, sufficient water and snacks, appropriate layers of clothing for changing mountain weather, a map or GPS device (like komoot's app), and a first-aid kit. Trekking poles can be very helpful for stability on steep and rocky sections.
