Starting at Av. Paulista 2 in Bela Vista, you'll open the Explorial app, enter the 6-digit game code that you received by text and Viator chat message, and join the flow of Brazil's most famous avenue. The tour is fully self-guided — no guide, no fixed start time, just your group and the city. Japan House opens the hunt: riddles explore the wooden facade by Kengo Kuma and the deep ties between São Paulo and the world's largest Japanese community abroad. Then Parque Trianon swallows the street noise whole — a preserved patch of Atlantic rainforest where trivia hides beneath century-old trees. At the Edifício Gazeta, clues trace the avenue's rise from coffee-baron mansions to media towers and Sunday street festivals. Around two hours later, the last challenge drops. Winners get the leaderboard; everyone gets the Paulista sunset.
