Indoor play parks: the safe bet
- Monstrofun, in Martigny: a large indoor play park where children climb and let off steam safely, whatever the weather. The birthday format par excellence for 3 to 10 year olds.
- Anniviers Indoor Park, in the Val d’Anniviers: trampolines, inflatable structures and areas for the youngest. Handy for families on holiday in the valley.
Challenges and adventures for older children
- Prison Island, in Sion: cells full of puzzles and cooperative challenges, Fort Boyard style. The group of guests becomes a team, and that changes everything.
- SionEscape: immersive rooms and urban investigations for children who like thinking together.
- RealFly, in Sion: the sensation of free fall from age 5, with no plane and no vertigo. The birthday people are still talking about months later.
- EVA Martigny: a virtual reality arena where you really move around, perfect for teenagers.
Birthdays in the great outdoors
- Parc Aventure de Sion, at the Domaine des Îles: treetop courses and zip lines by the water, from spring to autumn. The setting of the Domaine des Îles lets you extend the day with a picnic and a swim.
- Le Labyrinthe Aventure, in Evionnaz: a huge hedge maze and games galore. Groups of children can spend hours there.
- Western City: a Wild West theme park with ponies, games and challenges, for a birthday of cowboys and sheriffs.
The creative option
- L’Épicentre, in Martigny: workshops, games and cultural moments in a friendly venue designed for families. A gentle alternative to parties that run on adrenaline.
Our tips for a successful Valais birthday
- In summer, think about morning slots for outdoor activities: the heat of the Rhône valley soon makes itself felt.
- Check the minimum ages, especially for RealFly and treetop courses where the child’s height also counts.
- The venues in the valleys (Anniviers, Evionnaz) are ideal during the school holidays, when families head up to the resorts.
- Book early for Wednesdays and Saturdays: families in Valais have their habits.
