Le Nid d'Aigle from Bionnassay

Description

Starting from the charming village of Bionnassay, this hike takes you on a journey through the mountain's floors, offering a gradual immersion in the wilderness of the Mont-Blanc massif.

Departure is from the Crozat parking lot above Bionnassay. You soon enter a coniferous forest, where the air is fragrant with resin and the soft ground absorbs your first steps. The gentle ascent allows you to appreciate this peaceful atmosphere before reaching the high mountain pastures and meadows, where the horizon opens up and panoramic views of the Bionnassay glacier begin to unfold.

As you progress, the vegetation becomes sparser and the air cooler, reflecting the increasing altitude. You soon reach the Plat de l'Are, a clearing where you can see far into the distance, before entering the more mineral section of the trail. The climb becomes steadier, with the path winding under the imposing face of the glacier. A passage equipped with cables and metal stairs adds a playful, airy touch to this final ascent.

After around 3h15 of effort, you reach the Nid d'Aigle (2,372 m), at the gateway to the high mountains. This emblematic site marks the start of the royal Mont-Blanc route and the terminus of the famous Tramway du Mont-Blanc. The scenery here is breathtaking: the Bionnassay glacier seems within reach, and the surrounding peaks rise majestically before your eyes.
