Monstrofun, indoor play park in Martigny

A playful interlude in the heart of Valais

Monstrofun is a large indoor play park in Martigny, designed for families looking for a simple idea to move and change their minds. The atmosphere is friendly, with laughter, sliding, and jumping. It’s the kind of place where your children can expend their energy without limits, while you finally get a bit of a breather.

What your children will discover

Here, we climb, crawl, and slide. The foam structures and nets invite exploration without fear. Generally, you'll find multi-lane slides, monkey bridges, giant balls, trampolines, and a zone reserved for toddlers. Children love to test their balance, invent courses, and make new friends on site. It’s physical, sensory, and very social.

Before you go

• Ages: suitable from about 2 years up to 10–12 years. Toddlers benefit more from the dedicated space, which is quieter and at ground level.
• Duration: plan for 1.5 to 3 hours depending on the day's energy. Wednesdays, weekends, and holidays are often busier.
• Type of activity: sporty and playful, with a good dose of gross motor skills. It works on coordination, balance, confidence, and socialization.
• Reservation and price: paid entry. Some time slots, birthdays, or holidays may require a reservation. Check hours and rates on the official website before you leave.
• Accessibility: the space is indoors. Access with a stroller is generally possible (often a stroller parking area at the entrance). For specific needs, contact the team before your visit.
• Attire and equipment: non-slip socks recommended (sometimes mandatory). Comfortable clothing, a water bottle, and a small snack if allowed. In summer, the interior remains pleasant; in winter, layers are quickly removed.
• Safety: protected structures, padded surfaces, and nets. Parents should keep an eye, especially on the younger ones.
• Season: perfect all year round, with a real plus in rainy or heatwave weather.

Parents' tips

• Arrive early in the morning to avoid crowds.
• Slip a spare pair of non-slip socks into the bag.
• Set a visible meeting point for the older kids.
• Remind the children: drink regularly and take breaks.
• For a birthday, book as early as possible.

Why we recommend it

Because it’s a safe bet for allowing children to expend energy, even when the weather doesn’t cooperate. We love the freedom of play, the safety of the structures, and the variety of challenges. Children gain confidence, develop their motor skills, and learn to play with others. And you leave with rosy cheeks and a big smile.
