💡 Insider Tips to Avoid Pitfalls
1. Don’t climb the castle at noon! The light is too harsh and backlit for photos; the morning light is softer and better for the tower top.
2. No need to buy boat tickets online in advance; just scan the code at the pier. The Swiss Travel Pass allows free rides.
3. Thun town is mostly flat, easy to walk the whole way, no need to rent transport.
4. Compared to the bustling Interlaken, Thun is better for relaxing and daydreaming. No rush, slow wandering is the essence.
