Augmented reality investigation game at La Creusaz, Trient Valley

A clever getaway above Les Marécottes

At La Creusaz, in the Trient Valley, an augmented reality investigation game transforms an alpine walk into a family adventure. You follow a route, scan clues, solve puzzles, all against the backdrop of the mountains. The atmosphere is relaxed, the scenery is grand, and the children have a real role to play.

What your children will discover

Between viewpoints, the app reveals characters, objects, and clues in augmented reality. Children observe, compare, manipulate the screen, and unlock stages. They love the mix of mountain myths, local nature, and small missions. The pace alternates between walking, observation games, and team moments. You learn without realizing it: place names, fauna, flora, orientation markers.

How it works on-site

• The principle: a mobile app guides you step by step. At each spot, a clue appears in AR and launches a puzzle.
• Duration: expect 1.5 to 2 hours depending on the children's pace and photo breaks.
• Level: easy to moderate walk on alpine paths. You walk leisurely, but good shoes help.
• Atmosphere: playful, calm, and curious. It’s more of a mix of walking and puzzles than a race.

From what age and for whom

The game is suitable from age 6 with the help of an adult. Children aged 8–12 can lead the investigation and read the clues. Teens appreciate the tech aspect and the freedom in the field. Toddlers can follow in a baby carrier, but a stroller is not ideal on the trails.

Do you need to book, how much does it cost

Most AR routes can be launched directly via an app. Depending on the season, access may be free or paid. Some versions require an activation code. Be sure to check the information and conditions for the day on the destination's website before you go. Cable car tickets are not included.

Access and logistics

La Creusaz can be reached from Les Marécottes, above Martigny. Access is generally via the Les Marécottes–La Creusaz cable car. By public transport, the Mont-Blanc Express serves the Les Marécottes station, then you walk to the cable car. By car, you drive from Martigny towards Salvan–Les Marécottes; parking is available at the start of the installation. Once up there, the game starts near the marked trails and viewpoints.

What we love about this activity

• An investigation that motivates children to walk and observe.
• The scenery: alpine pastures, forests, and the peaks of Valais in the background.
• The balance between digital play and nature. The screen opens the eyes to the terrain instead of replacing it.
• Accessible puzzles designed for family cooperation.

Before you go

• Download the app in advance if possible, and update your phone.
• Full battery and, if you have one, a small external battery.
• Closed shoes, cap, sunglasses, sunscreen.
• Windbreaker: at altitude, the weather changes quickly.
• Water bottle and a small snack; several spots invite you to take a break.
• Check the cable car schedule and the opening of the route according to the season.

Safety and accessibility

The trails are marked and family-friendly, but remain mountainous. Keep young children close, especially near slopes. A rugged stroller may struggle on some sections. For people with reduced mobility, AR works, but access to clue points may be limited by the terrain.

Benefits for your children

• Curiosity and observation skills, thanks to hidden clues.
• Logic, reading, and teamwork to solve puzzles.
• Confidence and autonomy in a natural environment.

Parents' tips

• Start early to avoid queues at the cable car and the heat.
• Set a rotation for holding the phone and keeping everyone’s attention.
• Take screenshots of important clues if the network is unreliable.
• Have a plan B in case of fog or forecasted storms.
• Keep an eye on the return route to not miss the last cabin.
