Above the fore-dam there is another bridge. These 2 bridges and the dam are the only ways to change sides in the area of the Aartalsee.

The Aartalsee lake is worth a visit for starters. Even on weekends, it's less busy. You can observe all kinds of birds.

The bridge separates the pre-dam from the main dam and, apart from the dam wall, is the only way to change sides of the lake without having to go around the entire lake.

Great mountain bike destination with good rest stops around the lake. However, on Sundays and public holidays, especially in good weather, it is totally overcrowded.

The Aartalsee is a lovely place to hike around. The route length, including the beautiful nature reserve is about 8 kilometers long. This path is very busy on the weekends as it is also used by skaters and cyclists. There are restaurants along the route offering food and drinks at moderate prices. There are sufficient parking spaces for cars and motorcycles for a fee. You can also find a motorhome parking space there.
