RiverSurfJam Thun 2023

RiverSurfJam Thun 2023

In the heart of Thun’s picturesque old town, the river wave at the Mühleschleuse shines in the autumn sun. The wave is affectionately and respectfully called “Monster” by the local surfers and on the 9th of September the area around this magical place will be transformed into a surf arena. 

The winner of the Rapid Surfing Discipline will be crowded at this event. 

The competition is framed by a local surf market on the Waisenhausplatz as well as busking of the highest order and thus also offers the interested public plenty of reasons to linger around.
