Starting from the Altiport area of Alpe d’Huez, the route meanders through open alpine meadows and larch woodland, framed by the craggy backdrop of the Grandes Rousses.
The trail’s highest point sits at around 2,080 metres, though the walk remains relatively flat throughout.
The jewel of the route is Lac Besson, a beautiful mountain lake nestled in a tranquil basin surrounded by rugged terrain. In summer, this area blooms with alpine wildflowers, and marmots are commonly seen darting through the undergrowth. Interpretation panels provide interesting facts about local plants and wildlife.
The trail is well-signed and mostly level, making it accessible for children and those unused to high-altitude walking.
The loop brings you easily back to your starting point near the Altiport, making this a perfect option for a serene and visually rewarding half-day hike.
