Heiligenberg Castle

Highlight • Castle

Heiligenberg Castle, located high above Lake Constance and visible from afar, shapes the Linzgau landscape, and is rightly considered the pearl of the Renaissance.

Schlosssee (Castle Lake) – Natural Swimming Lake, Salem

Highlight • Lake

Why keep looking for a parking space at Lake Constance, pushing hard together in the lido? Why pay admission?

Here at the Schlosssee in Salem-Mimmenhausen (access and parking from Mimmenhausen) the community has built an incredibly beautiful lido for young and old. With a water park for the little ones, islands and a giant pirate ship to climb and jump into.
Extensive sunbathing lawns with plenty of shade around half the lake offer plenty of space. You can throw yourself into the fray in the restaurant/playground area, but you can also quietly crawl further away.
Admission free!!!
Parking for many cars available.
Plenty of bicycle parking spaces available.
Various sports facilities available, see photos.
DLRG keeps bathing supervision with boat and several supervisors.

The buildings for the changing rooms and the restaurant/café were rebuilt in 2015/6 and are now top notch. The tenant is also new and really well organized.

A treat even without bathing suits:
A footbridge runs around the entire lake, which is great for walking (no bikes!) - unique!

P.S.: The locals, they go swimming here with their families, the crowds at Lake Constance are left to the tourists... (no offense meant, but reality)

Pfahlbaumuseum Unteruhldingen

Highlight • Historical Site

The stilt house museum Unteruhldingen is located on Lake Constance in Baden-Württemberg and displays archaeological finds and replicas of stilt villages from the Stone and Bronze Ages. It consists of 23 stilt houses, a museum building, and a research institute. The museum is known as one of the largest open-air museums in Europe and attracts more than 300,000 visitors annually. Stilt houses are remains of settlements from the Stone and Bronze Ages and are of great archaeological interest. In 2011, more than 2,000 stilt house sites in lakes and moors in Europe were declared UNESCO World Heritage sites. The excellently preserved stilt houses offer an insight into the lives of people from 7,000 years ago.
