You step off the metro into Ouchy and the lake breathes against the quay, cool and insistent, daring you to walk. The promenade leads uphill into a city that shifts from waterfront plazas to steeper, church-stepped streets; every turn in Lausanne feels like a new chapter.\n\nThis self-guided scavenger hunt uses the Explorial app to convert those chapters into puzzles: track down the Olympic clock, find plaques buried in façades, and answer questions that reward observation over speed. Lausanne's story — a medieval bishopric turned modern sporting capital when the International Olympic Committee made the city its home — peeks out in carved stone, civic squares, and views over the glacial bowl of Lake Geneva. The hillside here is a product of ice and time, terraces holding vineyards and neighborhoods that tilt toward the water.\n\nCulturally, Lausanne is French-speaking, compact, and café-forward; local life moves between markets, museum gardens, and commuter trams. Practicalities are simple: buy the ticket to receive an access code, download the Explorial app, and start at the Ouchy promenade. Expect 1–2 hours of walking with short bursts of stairs and cobbled lanes; the route is flexible so you can pause for a coffee, a photo task, or the sweeping lake view.\n\nBring a charged phone, wear grippy shoes for steps and cobbles, and plan for signal in narrow lanes. Go early for softer light and fewer crowds, and treat the game as a way to slow down — the city will reveal itself if you follow the clues.
