A few kilometres from Taninges, at the end of a road that climbs steadily up from the valley, the Sommand plateau opens up all at once. Alpine pastures, panoramic views, open space. You are far from narrow gorges or technical cols: here, vastness is within reach. It is one of the places where hiking in the French Alps does not require exceptional fitness to deliver a landscape worth the journey.
A plateau in the Chablais massif
Sommand sits within the Chablais massif, a broad mountain territory stretching between the Rhône valley and the Swiss border. The resort, shared between Mieussy and the Praz de Lys area, is well known in winter for its ski domain. In summer, everything changes. The lifts stop, the skiers leave, and the plateau finds its quiet again. What remains is a succession of open pastures, wide and well-marked trails, and skies you can see in full.
The most common starting point is near the Col de la Ramaz. From Mieussy, you reach this area via the road that climbs along the flank of the massif. Parking is easy, signposting is reliable, and the first metres of almost every route offer a gentle rise over short grass.
What you can actually do here
The choice of paths on the plateau is genuinely varied. You can stay low, wander between the mountain chalets and the cattle, or push higher for the views. Two well-documented routes capture this range:
- The hike from Le Jourdy connects the valley floor to the plateau via the Grotte du Jourdy and the Cascade du Saix. It is a loop of just over 8 km with just under 750 m of elevation gain. Allow around 2h50 at a steady pace. The route stays varied throughout, and the waterfall makes a natural rest stop.
- The loop to the Pointe des Chavannais sets off directly from the plateau and climbs to 1,811 m. Total distance is just over 7.5 km with 557 m of gain. In about 2h30, you can explore the upper section without rushing. The summit opens up views toward the surrounding Alps.
Neither route is technically demanding. They require no specialist gear. But both reward the effort honestly, especially in high summer when the vegetation is at its fullest.
Accessible does not mean effortless
Accessible does not mean you can set off in sandals. The trails on the Sommand plateau are open to a wide range of walkers, including families with older children, but a few basic ground rules apply.
- Hiking shoes are essential. The ground can be wet early in the morning or after a summer storm.
- Carry enough water. Reliable springs are not guaranteed across the plateau.
- Summer thunderstorms build quickly at altitude. Starting early gives you the best chance of being back down before the afternoon cells roll in.
- The sun is strong between 1,400 m and 1,800 m. Hat, sunscreen, sunglasses.
What about kids?
The Sommand plateau is often recommended as a good place to introduce children to mountain walking. That is fair, broadly speaking. The wide trails, the absence of exposed sections on the main loops, and the regular presence of cattle and alpine animals make the outing lively and concrete for younger walkers.
Short loops around the mountain chalets work from around age four or five for children who are used to walking. For the two routes described above, age eight to ten is a reasonable starting point depending on the child. These are guidelines, not fixed rules, but they help plan a day without pushing too hard.
When to go
From June through October, the plateau is accessible in good conditions. July and August offer the longest days, the most active wildlife and wildflowers, but also the biggest crowds at peak hours. Early September is often a sweet spot: the pastures are still green, the walkers are fewer, and temperatures become more comfortable for covering ground.
Avoid mid-August weekends during a heatwave. The lack of shade on the upper sections of the plateau makes the outing uncomfortable when the heat is at its worst.
The Sommand plateau is not a mythical summit, and that is not what it aims to be. It is an open, varied space, easy to reach from the valley, where you can spend a solid day in the mountains without committing to anything technically demanding. In Haute-Savoie, places like this are rarer than you might think.
