Gaudi City of Dreams Barcelona Self Guided Walking Quest

Barcelona has thousands of guided tours - Questifan is different. This is a self-guided mystery quest where you become the detective, not just a listener. No group to keep up with, no fixed schedule - solve Gaudí's hidden riddles at your own pace, powered entirely by your phone. Every stop is a real puzzle built from architectural details most tourists walk straight past: the exact number of towers on a facade, the hidden animal sculpted into a building's stonework, the true shape of a monument disguised as abstract art. Get stuck? Unlock progressive clues at your own pace - no rushing, no waiting on a guide. Available in English, Spanish, French, German, and Russian, and playable anytime - start whenever you land in Barcelona, no booking a time slot required. One unlock code gives you unlimited access, so you can pause, restart, or replay the story whenever you like. This isn't a walking tour you follow. It's a mystery you solve.
