Groningen is the Netherlands' northern secret — a student city with a medieval tower, a world-class museum, and a hidden alleyway that's been there since the 1400s.

This app-led scavenger hunt takes you through Groningen on foot, using phone-based riddles to guide you from one landmark to the next. No guide, no fixed start time.

• Start whenever you want and move at whatever pace suits the group

• Perfect for families, friends, or curious solo explorers

Around 2 hours, any group size, available in English.

The Martinitoren has been watching over Groningen for 600 years — time you met it properly.
