You step out of Baker Street tube into a London that still leaks gaslight in its shadows: cobbled side lanes, clipped hedges, and the low hum of a city that never quite sleeps. The game pings your phone and Holmes' voice — or his challengers — begins to narrate your first clue. The route pushes you through Marylebone's narrow streets and into the wide, tree-lined crescents of Regent’s Park, a 5 km loop that moves at the pace of your curiosity.

You step out of Baker Street tube into a London that still leaks gaslight in its shadows: cobbled side lanes, clipped hedges, and the low hum of a city that never quite sleeps. The game pings your phone and Holmes' voice — or his challengers — begins to narrate your first clue.

The walk threads fiction and real history: Arthur Conan Doyle’s detective lives on here, but so do 19th-century town plans and John Nash’s green axes. The geology is simple—London clay under foot—so expect paved surfaces, park paths, and the occasional sloping carriageway rather than steep climbs. Cultural notes appear in shopfronts and parish churches; the area has long been a mix of bohemian residents, medical schools and quiet domestic streets where Victorian London hardened into modern life.
Practical guidance: the game is self-guided, lasts about two hours and covers roughly 5 km. It’s fully wheelchair and stroller accessible on paved routes, with minimal elevation gain. You’ll need a smartphone and the Telegram app to receive your unique game code. Bring comfortable walking shoes, a portable charger, and a weather layer—London weather changes fast. Play during daylight for best visibility of visual clues and to keep public garden access simple.
Pace yourself: this is about observation, not speed. Pause at benches, read plaques, and let the city’s details point you to the solution.
