To make sure it is safe to swim, the swimming zones in the river are clearly marked. The swim route starts on the banks of Kleinbasel near Museum Tinguely and finishes just before the Dreirosenbrücke bridge. The red marker buoys serve to protect swimmers as well as boaters from accidents. Incidentally, you can easily get to the starting point near Museum Tinguely by public transport – which is free of charge with the BaselCard.
