Want to turn the giant murals of Paris's 13th arrondissement into a game? Boulevard Paris 13 brings together street art and geocaching in one of the city's major urban-art districts. The associated trail encourages you to observe the artworks and neighbourhood rather than simply walk past the buildings.
Hunt for details among the murals
The route centres on the 13th arrondissement, around Place d'Italie and the monumental murals of Boulevard Paris 13. It draws on observations of the urban environment and several forms of street-art geocaching.
What exactly is geocaching?
It's a GPS-guided treasure hunt: your phone takes you to coordinates where you either search for a physical cache or complete a digital challenge. The Adventure Lab route associated with Boulevard Paris 13 is the digital kind, using artworks and neighbourhood details as clues.
Is it free?
The Adventure Lab experience is free to play with a free account and the dedicated app. Additional physical caches depend on their status on Geocaching: most are available to Basic account holders, while some are reserved for Premium members. The outdoor street art itself is freely accessible.
Adventure Lab and additional caches
An official Boulevard Paris 13 – Bonus Labs cache is associated with the Adventure Lab route. Other street-art caches in the area are also active in 2026, offering a whole series of challenges rather than a single hidden item.
Before you set out
Murals and caches can change. To avoid relying on a specific painting or box, use the up-to-date stages and cache statuses shown on the Geocaching platform on the day of your outing.
The real appeal is having a playful route for exploring a collection of monumental artworks spread throughout the 13th arrondissement on foot.
