Thun Self-Guided City Walking Tour & Scavenger Hunt

Thun stacks a 12th-century castle above a medieval market street with raised sidewalks — and drops the whole arrangement beside a turquoise Alpine lake with the Eiger on the horizon.

This app-led scavenger hunt takes you through Thun on foot, using phone-based riddles to guide you from one landmark to the next. No guide, no fixed start time.

• Cross the Rathausplatz, the arcaded square at the foot of the castle hill • Climb to Schloss Thun, the white keep with four corner towers above the roofs • Visit the Stadtkirche, whose octagonal tower watches over lake and old town

Available in 24 languages including English, French, German, Spanish, Italian — see the full list when booking and choose yours when you start the game in the app. Around 2 hours - any group size.

By the last riddle, the gateway to the Bernese Oberland will have opened up completely.
