Mülheim an der Ruhr is a hidden gem of the Ruhr Valley, where medieval history, lush green spaces, and a lively modern waterfront meet in a surprisingly compact city. An interactive outdoor scavenger hunt lets you explore the towering walls of Schloss Broich — one of Germany's oldest surviving Carolingian palace complexes — stroll along the revitalised Ruhrbania promenade beside the flowing River Ruhr, and discover the shaded trails of the Uhlenhorst city forest. At every waypoint, fresh quiz questions bring local history, nature stories, and industrial heritage to life, turning a walk into a hands-on learning adventure for everyone.

Whether you're visiting as a family with kids, exploring with a group of friends, or discovering the city as a curious newcomer, quiztrip.app turns every walk along the Ruhr riverbanks or cycle through the city forest into a fully interactive experience. The family-friendly Kids Mode keeps young adventurers engaged with age-appropriate questions about animals, local legends, and the fascinating story of the Ruhr's transformation from coal and steel to green parklands and modern waterfront architecture. It's the outdoor activity in Mülheim that gets the whole group talking, laughing, and genuinely curious about the city around them.

Getting started is effortless. Simply choose a distance — anything from a two-kilometre stroll through Broich's historic streets to a ten-kilometre riverside ramble — and a custom GPS route is built from your current location. Along the way, you'll unlock quiz questions at landmarks discovered by the system in real time. No printed maps, no group leader required, no app download needed.
