Madrid Self-Guided Walking City Tour & Scavenger Hunt

Madrid's grandest mile runs from a palace that's actually a post office to a glass palace that was built for plants — and this trail connects them one riddle at a time.

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

• Size up the Palacio de Cibeles, the cathedral-like former post office on Madrid's most famous plaza • Wander into the Parque del Retiro, the city's great green escape • Find the Palacio de Cristal, a Victorian greenhouse turned art space by the lake

Available in 24 languages including English, French, German, Spanish, Italian — see the full list when booking and choose yours when you start the game in the app. Around 2 hours - any group size.

By the finish, the showpiece side of Madrid will feel less like a postcard and more like a place you've figured out.
