World City Trail

World City Trail turns sightseeing into a game. Each trail is a self-guided scavenger hunt through a city's highlights and hidden corners: you follow clues from station to station, solve riddles at each stop, and discover stories a normal tourist walks straight past.

There's no guide and no schedule — you start whenever you like and play at your own pace, with coffee stops, photo breaks and detours whenever you want. A typical trail takes around 3 hours on foot and works for couples, friends, families and teams. Optional voice narration is available, and each city is playable in 6 languages (10 supported overall).

Trails are available in 167 cities across 37 countries, from major capitals to smaller historic towns, with pricing from €7 per person for groups.
