The Altmuehl Sea, part of the Franconian Lake District, has the size of the Upper Bavarian King’s Lake (4.5 km²). The lake has a storage space of 13.8 million cubic meters of water. In the lake is a 1.2 km² large bird island. Around the lake is a ring dam with a length of about 12 km, on whose crown a cycle and footpath was laid. The Altmühlsee – gently inserted into the charming, spacious landscape of the upper Altmühltal – is ideal for sailing, surfing, bathing, cycling and hiking. A shipping line connects the three sea centers and allows the Franconian landscape to pass by peacefully. In about 40 minutes you are from our house at the lakes. The Altmühlsee, which originated in the years 1976 to 1984 before the gates of the town of Gunzenhausen, is part of the system “Reconciliation of Altmühl- und Donauwasser into the Regnitz-Main area”. In the Altmühlsee, excess floods are stored and transported over the approx. 8.7 km long overhead line under the European main watershed to the small and large Brombachsee.
