Switzerland Mühleschleuse, Surf spot, Thun

This is an old lock built in 1723, which also serves as a covered wooden bridge spanning the Aare. It can be crossed on foot, and you can even get a close-up look at the mechanism that operates the sluice gates. In summer, surfers take advantage of the fast, powerful wave created by the lock's current. It's a well-known spot for river surfing enthusiasts in Thun.

You are in a pedestrian zone. However, the city has public car parks nearby.
