As you stroll through the Botsberger Riet nature reserve (directly behind the Chocolate Factory of Happiness), you have to solve a number of tasks with the help of an app. To play you need your own smartphone or tablet with internet connection. Small groups can also play together on one device. The Outdoor Fun Tour starts at the entrance to Maestrani's Chocolarium during opening hours. The 2.3 km route is also suitable for baby buggies.

The outdoor play tour is free of charge. Simply download the app "Ambia" from the App Store (for Apple devices) or Google Play (for Android devices) - and start at our location. We recommend playing the game with the latest Android or iOS version on a newer device. The app is sometimes not available on mobile phones with foreign network providers.

The app requires 700MB of memory and a large amount of energy from your smartphone. Please start with a full battery. On site you have the possibility to borrow a Chimpy Powerbank for CHF 4.00. The deposit is CHF 15.00.
