Wasserberg hill, which in German means “Water Mountain” is an important natural attraction of Pegnitz. Franconian Switzerland where the town is located has many such natural “wonders” but still, what you see here is amazing. Mühlbach river head is located next to the hill where cavern springs were found. This native zone was called “Karst Wonder” for its unique landscape.
Local residents might be exaggerating the “wonder” part a bit but the territory around Wasserberg Hill is really worth seeing because of the number of cavern reservoirs and uniqueness of the local soil, which is literally soaked with karst and thus forming numerous voids as a result of washing out of rock. There are also many beautiful karst caves, but you should not try to enter all of them, and you won’t even be able to do so with some of them, as they are too low. Some are deep underground but you can see them through special “windows”, which are made in the most interesting places. An excursion, whether on your own or with professionals from the local nature society, can last longer than an hour, so it’s useful to take food and comfortable shoes along.
