The medieval castle complex in the middle of the Innauen is a special excursion destination. The Chancellor's Room, the exhibition and the vaulted cellar bring the history of Frauenstein to life. Events also take place here. Mostly open until the end of September. In October usually only on weekends.

The former farmer's house is a listed building and is a two-story block building in a corner location, with a protruding flat pitched roof, knee wall and gabled gable, built after a fire in 1814, roof later. A perfect photo motif in spring and summer, when it's usually blooming on the balcony.

The location of the power plant is also known for the nearby Frauenstein Castle, which offers a wonderful rest for the many cyclists along the Inn Cycle Path. There are not only sporting achievements to be seen here, the power of the Inn is also impressive: since 1943, the Ering-Frauenstein run-of-river power plant has been generating electricity from 100% hydropower and supplies around 97,000 households with green electricity. In the next few years, the power plant will undergo extensive modernization. Ecological measures, such as the construction of a fish pass, have already been implemented.

Wide gravel path on the Inn, little protection from the sun. From time to time there is also a break bench for a picnic, unfortunately without a trash can 🚮.
