This challenging loop usually takes around 6 hours to complete. However, your actual time may vary depending on your fitness level, pace, and how long you spend enjoying the stunning high-alpine scenery.
The terrain on this loop is diverse and often rugged, characteristic of a high-alpine environment. You'll encounter a mix of alpine hiking paths, standard hiking paths, and mountain hiking paths. Expect natural, unpaved, and gravel sections, with very minimal road portions. The route features a spectacular mineral setting, including rocky parts and potentially large boulders.
This loop starts from Lac Besson. Parking is generally available in the vicinity of Lac Besson, which serves as a common starting point for many hikes in the area. It's advisable to arrive early during peak season to secure a spot.
No, this loop is considered a difficult hike and is not suitable for beginners or families with young children. It demands very good fitness, sure-footedness, sturdy shoes, and alpine experience due to its length, elevation gain, and rugged high-alpine terrain.
Dogs are generally allowed on this trail. However, as it's a high-alpine environment, it's recommended to keep them on a leash to protect local wildlife and ensure their safety on challenging terrain. Always practice responsible pet ownership and pack out any waste.
This loop offers breathtaking high-altitude scenery. You'll pass several stunning lakes, including Lake de la Fare (at 2,645m), Lac du Milieu (at 2,675m), and Lac Blanc d'Alpe d'Huez. You can also enjoy views of the View of the ruisseau de la Fare. The trail provides expansive panoramic views of the majestic peaks of Oisans, La Meije, and Pic d'Olan.
The best time of year to hike this high-alpine route is typically during the summer months (July to September) and early autumn. During these periods, the snow has usually melted, and the weather conditions are more favorable for high-altitude trekking. Always check the local weather forecast before heading out.
Generally, there are no specific permits or entrance fees required for hiking this trail in the Grandes Rousses area. However, it's always wise to be aware of any local regulations, especially concerning protected areas, and to respect the natural environment.
Yes, the Refuge de la Fare is located along the route. This mountain hut can serve as a point of interest, a potential rest stop, or even an emergency shelter, depending on your needs during the hike.
Yes, this route also passes through sections of other official trails, including XC 11 Les Lacs, Les Lacs, Sentier des Avachis, Boucle des Lacs, Le Dôme, Les Chamois, and Bord lac blanc.
Given the difficult nature and high-alpine environment of this loop, you should bring sturdy, waterproof hiking boots, appropriate layered clothing for varying weather conditions, plenty of water, high-energy snacks, sun protection (hat, sunglasses, sunscreen), a map and compass or GPS device, and a first-aid kit. Trekking poles can also be very helpful on the rugged terrain.
Superb day on the heights of Alpe d'Huez, in the Rousses massif, with an incalculable number of lakes and magnificent trails. A very steep climb by a not so great ski slope, but the rest was sublime, and the descent towards the refuge de la Fare is fantastic, technical as desired but not at all exposed. At the refuge, a short break "crepe with homemade blueberry jam" washed down with spring water. In short, an excellent day!
