Isar River Bathing
You can go swimming in Munich even without paying admission, e.g. in the river Isar. Especially on a hot day in the summer many people like to go with the flow of the river. They enter the river for instance at the Flaucher in the borrow Thalkirchen and get out at Deutsche Museum in the district Glockenbach - though it should be mentioned that this is something for experienced swimmers only.
In Munich’s district Au there are many steps along the river. Here you can relax and put your legs in the water of the river.
On a hot day some people even jump for quick refreshment into the Eisbach, the stream that goes through the English garden (Englischer Garten).
