Waldhaus at Deininger Pond

Highlight • Restaurant

The natural moor lake is a relic of the last ice age. The melting water currents that arose as a result of the warming washed out what is now the Gleißental and left behind the shallow lake. This is embedded in a charming landscape, the landscape conservation area "Südliches Gleißental" in the communities of Dingharting and Oberbiberg. In the years 1976/77 it was desludged and leased by the recreation area association. The lake is followed by a reed belt and a moor area, both of which may not be entered. Today the lake is a popular recreation area and, with its wooded surroundings, an attractive area for jogging in the warm season.

Bismarck Tower Assenhausen

Highlight • Monument

When you approach the Bismarck Tower, you first think of a Nazi monumental building. But it is older, it was created at the end of the 19th century. Some wealthy and enlightened citizens had it built to thank Bismarck for joining Bavaria to the German Empire. There are many details to discover, such as beautiful Art Nouveau fonts. And the view is just amazing!

Unfortunately, you can't climb to the very top of the Bismarck Tower near Assenhausen - but otherwise it's a very beautiful building

Suitable for cyclists and hikers. Beautiful marked paths. For cyclists who continue on the road - good luck - 12% gradient. You either need good stamina or a lot of strength. Or you can do it like I do, following the well-known saying: "If you love your bike, you push it"...😅
