La Boîte aux Lettres walks

Straddling the French-Swiss border, between Sixt-Fer-à-Cheval and Champéry, this marked trail takes you between alpine pastures and high mountains. The Dents Blanche pass is remarkable for its geology, with its tightly folded limestone layers. A steep descent down a rocky chimney (with cables) takes you to the Col de Bostan, on the French-Swiss border. The Pas de la Bide, a tricky passage with its famous letterbox, leads to the Brame mountain pastures and the Auberge de Bonavau.

After this detour on the Tour des Dents Blanches, you will rejoin the Tour des Dents du Midi and finish at the Auberge de Salanfe. Along the route, you will come across the Sauflaz, which you will overlook at the Pas d'Encel via a passage equipped with chains. In the Vallon de Susanfe, you can admire the Ruan massif. At the Col de Susanfe, you can contemplate the Haute Cime and the Dent Jaune. Further on, you will notice the Refuge des Dents du Midi.

A big day with spectacular scenery. The Pas d'Encel pass is a little tricky to navigate to reach the foot of Mont Ruan. Reach Haute Cime, the highest point of the Dents du Midi at 3,257 metres, via the Col de Susanfe, then descend to the Auberge de Salanfe on the edge of the lake.

Starting from the Susanfe hut, climb up to a unique viewpoint in a high mountain setting!

The usual route to the Susanfe hut from Campéry starts in the forest before emerging onto the Bonavau mountain pasture. Below the imposing peak of the same name, the trail climbs up a path with a few equipped sections and crosses the Pas d'Encel. The final ascent of the Susanfe valley takes place in a high mountain setting.

Pass through the listed site of dinosaur footprints, then climb up to Cheval Blanc and reach the summit of Buet via the ridges. A difficult alpine route classified as T4 with breathtaking views of the Aiguilles Rouges.

This route begins with a detour off the beaten track, suggested to us by the refuge warden, to reach the Col de la Terrasse. An alpine route with the Emosson dam in the background and a chance to discover the lakes at the Col du Corbeaux. After a long descent at the foot of Mont Buet in the Tré les Eaux valley, cross a long ledge equipped with cables and ladders to finally reach the Chalets des Granges and arrive at the Couteray car park.

Hike starting from Croix du Culet, accessible by cable car. The signposting is particularly good at each intersection. Head towards Pas de Chavanette, then Lapisa, La Pierre, La Poya and climb up to the Col de Cou hut for a magnificent view. Then descend towards Croix d'Incrène via Arête de Berroi (truly magnificent, the most beautiful part of the circuit) and then towards the Barme refuge. Descend towards Champery. This is the least attractive part of the route, but it is difficult to avoid this road.

This stage partly follows the Tour des Dents du Midi, with a remarkable passage at the foot of the Sauflaz Gorges. As you climb back up towards Bonavau, you will switch to the Tour des Dents Blanches. The Barme Plateau is a magnificent place to contemplate these famous white teeth.

A lovely hike in the Cirque du Fer à Cheval with its remarkable waterfalls, a stop at the Bout du Monde, with a balcony path through the forest to reach the Chalet du Boret, and a steady climb to reach the Refuge de la Vogealle perched on a pretty plateau. Important note: this route requires a taxi shuttle from the Cascade du Rouget to the Cirque du Fer à Cheval (14 km) to reduce the walking distance.
