are you ready for a secret encounter?
Together with Radiomakers Desmet we created a musical treasure hunt throughout the city. To make the journey you need the Hidden Gems app, which you can download for free in the app store. The audio tour is available in six cities: Amsterdam, Groningen, Utrecht, Rotterdam, Delft and Nijmegen. You can choose from a Dutch or English spoken version.
The search begins at the Central Station and leads you along 5 different places in the city, which are indicated in the app. Depending on your exact route and pace, the trip takes about 1.5 hours.
At the last stop, The Park, we have hidden a real treasure. Can you find it? Check out the directions carefully. A nice surprise awaits you.
The Hidden Gems app uses GPS. Turn on Location Services / GPS on your phone and allow the app to use it.
We recommend using real headphones instead of earplugs for the optimal audio experience.
Keep an eye on your surroundings and traffic during the tour!
Listen here to some short fragments from the Treasure Hunt as a preview.
You can do the tour at any time you like. All you need is the app on your smartphone, headphones and comfortable shoes.
The app is totally free! Plus we do not ask for any personal information. If you want to limit your data usage, you can download the audio in advance (via WiFi).
All music from the app is on the Calefax album Hidden Gems and is available in our webshop and via iTunes.
The Hidden Gems app is made by Calefax in collaboration with Echoes and Radiomakers Desmet:
Concept and montage – Marije Schuurman Hess and Bente Hamel
