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 rock formations are impressive and highly recommended. But be careful, there is a road leading through the valley. It is a direct connection from Eselsburg to Herbrechtingen and is driven on the right. It's a little quieter on the small hiking trail parallel to the road, on the other side of the floodplain.

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.
