Starting at Rue du Pont 25 in the old town, you'll open the Explorial app, enter the 6-digit game code that you received by text and Viator chat message, and descend toward Lake Geneva's most famous shoreline. The tour is fully self-guided — no guide, no fixed start time, just your group and the city. The Statue de Freddie Mercury strikes his iconic pose against the lake — fans still leave flowers for the Queen frontman who recorded here and loved this town. Riddles hit all the right notes. On the Place de l'Eurovision, trivia recalls the smoke on the water — the 1971 casino fire that gave Deep Purple a riff and Montreux a legend. Then the Jardin du Montreux Palace offers Belle Époque elegance, palm trees and Alps sharing one impossible frame. Around two hours along the flower-lined promenade. The final chart position is decided by the leaderboard — no jury votes.
