Réserve naturelle nationale de Passy walks

A superb walk facing the long barrier of the Rochers des Fiz (or Chaîne des Fiz – Massif de Platé, Haut Giffre), in an exceptional setting with a section of the route running alongside the Souay torrent. When the sun is shining, the reflections of Lake Pormenaz are truly beautiful.

A very pleasant hike offering beautiful views of the Fiz mountains with some lovely sections (beautiful waterfalls).

An extraordinary hike that almost forms a loop, starting from the Châtelet car park; a complete change of scenery guaranteed in an exceptional environment (Passy and Sixt nature reserves; Platé desert). You will need two vehicles.

Crossing the Buet, ascending via the Refuge de Grenairon and descending via Les Fonts. It is a long loop with a significant elevation gain and a section at an altitude of 3,000 metres. Having done this hike again in the direction of Grenairon chalet to Fonts chalets, I am repeating the description as it is much easier, shorter (approx. 9 to 10 hours), and it is easier to see the rest of the path from above when descending from Beaux Prés.

The first stage of a two-day excursion to Lac d'Anterne, this day allows us to reach the Refuge du Col d'Anterne via Les Argentières and Lac de Pormenaz.

From the Moëde Anterne refuge where you will have spent the night, there is a beautiful climb to the Col d'Anterne, facing Mont Blanc, then a return trip to Lac d'Anterne. The descent from the pass is via the 4X4 track to spare your joints.

Second stage of the Tour des Aiguilles Rouges. This second stage follows the itinerary of the Mont Blanc GRP®. Hike through the Passy Reserve to the Col de Salenton. It's optional to climb the Mont Blanc des Dames: le Buet. Descent through the Vallon de Bérard nature reserve to the mountain hut.

A lovely hike passing through the Col de Salenton, descend to take the balcony path through the mountain pastures of the Vallée de la Diosaz. Continue on to the Refuge de Moede-Anterne, then the Col d'Anterne and descend to the magnificent Lac d'Anterne. Then reach the Refuge des Fonts via a pretty path passing through the Petit Col d'Anterne. ⚠️ This route crosses the Aiguilles Rouges nature reserve. Please respect the regulations in force. See practical information.

First stage of the Aiguilles Rouges tour. This stage begins with a forest climb with views of Mont Blanc and the Bossons glacier. Continuing with a panoramic hike over the Passy reserve, we pass Lac de Pormenaz and arrive at Refuge de Moëde Anterne which overlooks the Mont Blanc mountain range.

A route through a very wild landscape between two bucolic lakes, with views of Mont Blanc. Very stony trail, ideal after rain. Shaded route in the first and last quarters.

Straddling the Franco-Swiss border, the Dents Blanches, Dents du Midi, Tenneverge, Mont Ruan and Aiguilles Rouges. An area strongly shaped by the folding of the Alps, with surprising landscapes ranging from lunar deserts to high-altitude lakes, waterfalls and forgotten mountain pastures. A wild and unspoilt nature that only hikers can discover. Alpine valleys, often isolated by "pas", technical and cabled paths opening the doors to this universe of raw and grandiose nature...

If you spend a night at the Moëde Anterne refuge, you can make a round trip to Lake Anterne, taking a different route on the descent from the refuge.Beautiful view of Mont Blanc. Three lakes on the programme: Lac de Pormenaz on the first day, then a night at the refuge, Lac d'Anterne the next day, which reflects the rocky ridge of Les Fiz, and Lac Vert near Plaine Joux, to be saved for the return trip.
