Sion Self-Guided Walking Tour with Riddles & Scavenger Hunt

Riddles and landmarks: navigate Sion's medieval heart on your phone

This self-guided scavenger hunt takes you through Sion on foot using app-based riddles to navigate from one landmark to the next. Download the Explorial app, enter your game code, and set off from Place de la Planta into the old town at your own pace with no fixed start time or guide. The trail passes the Cathédrale Notre-Dame du Glarier, La Grenette grain hall, and the Place du Midi, where medieval Sion meets the modern city. Around 2 hours, available in 24 languages, with total flexibility to pause, break and explore as you choose.

The experience

You arrive at Place de la Planta, download the Explorial app to your phone, enter the 6-digit game code you received by text, and start whenever you're ready. The riddles guide you from one stop to the next: no guide waiting, no group schedule to follow, just your group and the city. This means you walk at your own pace, take breaks when you want, and spend as long as you like at each landmark without anyone hurrying you along.

The trail threads through Sion's layers. At the Cathédrale Notre-Dame du Glarier, riddles sit beneath a Romanesque belfry that has survived fires and centuries of Valais politics. La Grenette, the elegant old grain exchange where farmers once haggled under the arcades, adds a mercantile chapter to the city's story. On the Place du Midi, you move between café terraces and shopfronts where the medieval town gives way to the modern one, with the castle hills of Valère and Tourbillon visible from almost every angle. Each riddle unlocks a piece of Sion's 7,000-year history (the wine, the politics, the architecture), and you compete against your group's score or the city's high score as you solve them.

The app works on iOS or Android and requires a fully charged smartphone with active mobile data (avoid VPNs and city Wi-Fi, which can disconnect the app). Entrance fees are not required. All puzzles relate to public areas. Around 2 hours of light walking covers the whole route, though you control the pace entirely. The game is available in English, German, French, Italian, Spanish, Portuguese and 18 other languages. Choose your language when you start.

Is this one for you?Two hours of walking leaves the rest of your afternoon or morning free, so this suits a traveler with a few hours to spare in Sion rather than a full day commitment. The self-guided format means no waiting for a group to gather or a guide to arrive. You move on your own schedule and can pause for a long lunch or a vineyard stop without holding anyone else back.
