The mountains in summer with children: our favourite valleys in Valais

Kidora Added on 27 July 2026

The Valais mountains in summer are the family plan par excellence: cool air when the lowlands are stifling, alpine farms, downhill scooters and trails with stories to tell. Here are our favourite valleys, each with a ready-made programme.

From the val d’Illiez to the val d’Anniviers, every valley has its own character. All of them are reached by postal bus or mountain train, which is already part of the adventure.

Champéry and the val d’Illiez: the Dents du Midi as a backdrop

The val d’Anniviers: stars and alpine pastures

Ovronnaz: the alpine pasture at 2,000 metres

The Trient valley: trains and gorges

Our mountain tips with children

  • The weather first: in the mountains it changes fast. Storms are frequent in mid-afternoon in summer: set off early and plan an indoor fallback.
  • Layers, always: a 10-degree difference between the valley floor and the alpine pastures is the norm.
  • The postal bus is part of the game: bends, the three-tone horn and plunging views — children love it. Check the timetables, as frequencies are mountain-style.
  • Look out for “family” lift passes: summer chairlifts and funiculars often have very gentle children’s rates; check the resorts’ websites.
  • The summer toboggan run, the essential of the season: almost every Valais resort has its rail descent; we have gathered the best in our guide to summer toboggan runs in French-speaking Switzerland.

Frequently asked questions

Which Valais valley should you choose for a family summer holiday?
Champéry and the val d’Illiez offer the most supervised activities (treetop courses, scooters, a farm), the val d’Anniviers appeals to contemplative families with its villages and Le Chemin des Planètes, and the Trient valley concentrates mountain trains and spectacular gorges.
What can you do in the mountains with children when it rains?
Anniviers Indoor Park and its trampolines, the escape room in Grimentz or a trip down to the museums of Martigny and Sion save the day. In the mountains, always have an indoor plan B.
Are the mountains in summer suitable for toddlers?
Yes, if you choose gentle activities: the Mini Zoo de Jorasse, la ferme de la Rochette or the VerticAlp trains all work from age 2–3. Bring a baby carrier for the trails and warm layers.
Do you need a car for these Valais valleys?
No: Champéry is served by the AOMC train from Aigle, the val d’Anniviers by postal buses from Sierre, and the Trient valley by the Mont-Blanc Express from Martigny. The journey is part of the adventure.
