I live in Basel, Switzerland, where it is common sport to jump into the river Rhine on a hot day, and float right through historic downtown. It’s a marvellous thing, even just to watch. Really adds to quality of life! Edit: Missed the other comment by a fellow Baseler.

Same on the Limmat in Zürich, such a relaxing 2-hour float down the river (only interrupted by the deadly dam in the middle).
