The free summer event brings a Mediterranean festival mood to Basel. Performing on a floating stage on the Rhine with a sail-shaped canopy, insider tips and well-known bands from Switzerland and abroad will delight up to 50,000 visitors. Take a seat on the steps of the Kleinbasel river bank and let the music and the atmosphere wash over you.
