Thaneller (2,341 m) is really popular summit due the magnificent views of beautiful Plansee and Heiterwanger see as well as Zugspitze massif, Tannheimer mountains and Allgäu alps. There is an easier route (T3) to the summit from south side from Bergwang. However, a more challenging and exposed route goes through the northwest flank via so called Werner-Riezler-Steig. The current route combines both of them with Werner-Riezler-Steig on ascent.
Ascent: The starting point of the route is the train station Heiterwang-Plansee. You follow the signs towards Jochplatz over Bergwachtsteig. The path is not well marked but there are sometimes faint blue spots on the path. In the beginning the path goes over steep forest. You have beautiful views of Plansee and Heiterwanger see. At approximately 1550m altitude, there is a bifurcation, take the path on the right here towards Thanellerkar. The path soon starts to become more rocky and sometimes exposed. Some sections are secured with chains. After traversing the mountain on the north, the goes a bit down towards Thanellerkar.
From Thanellerkar the signpost on the big rock says still 2.5 hours to the summit. In the beginning you have to ascent on steep scree, before arriving to the north wall of the mountain. Werner-Riezler-Steig starts here, the path is well marked throughtout with red dots. Some of the sections are secured with steel cable but not everywhere. Some sections require scrambling up to grade I. In early summer, there might still be old snowfields so taking crampons is a good idea. Also a helmet is recommended in this section.
Descent: From the summit follow the signs to Bergwang. There are no challenging sections on this part, and the trail is easy (T3). If you came by car, you can take the train from Bichlbach Almkopfbahn to Heiterwang-Plansee.
Webcam: Bergwang, although the summit is not visible in the webcam, still good to get an idea about the conditions.
