The ruins of Werdenfels Castle stand about 80 metres above the Loisach valley between Garmisch and Farchant in the county of Garmisch-Partenkirchen in Upper Bavaria. The spur castle was used until 1632 as the administrative centre of the County of Werdenfels, but began to fall into disrepair thereafter.
The castle ruins are freely accessible and are a popular hiking destination with a good view of Garmisch-Partenkirchen and the Wetterstein Mountains.
