The sunlight turns the water turquoise... No wonder, the water is very fresh and the pot is not as deep as the Blautopf. Very nicely laid out and well explained on boards.

The Brenztopf (source of the Brenz) is an absolute highlight on every tour. The previous speakers/writers have already mentioned the most important things. The Brenz finally flows into the Danube, which is known to flow into the Black Sea. The Kocher has its source a few km to the north. This flows into the Neckar, which in turn flows into the Rhine and thus into the North Sea.

In summer, a variety of leisure activities are possible: there is a pedal boat and rowing boat rental, berths for sailing boats, you can surf and sail, swim and lie on the sandy beach, and you can also fish. There is a circular hiking trail that takes you around the lake in about 45 minutes. The remains of the Buch fort of the Upper German-Raetian Limes can be seen in the shore area. Source: Wikipedia

A paved circular path leads around the lake. There are many places to rest and there is also a sunbathing area for bathers. However, it gets very busy here on weekends in the summer.
