This tour in the Hochkönig massif is rated as T4, T5 or T6 in many public sources. A rating of T4 feels wrong since it contains several climbing parts in grade II. Climbing is a little more difficult than Ehrwalder Sonnenspitze or Großer Waxenstein, but less exposed in the more difficult parts. Only parts of the climbing is secured by old steel ropes, some exposed but all with red markings. A small glacier (without crevasses) has to be crossed or climbed around in pathless terrain(II). A rating of T5 seems appropiate since alpine experience is required.
The hiking trail is easy from Hinterthal to Bertgenhütte(1845), scrambling starts at ~2170m on rock and schrofen(up to II). Taking the right one of the Teufelslöcher the view opens to a ridge leading up to the peak.
What follows is a small glaciated field, potentially snow covered until late in the season. After this some more scrambling awaits. This time up to II-III, depending on the chosen route.
Way down: Follow ridge north west(I-II), after a while descend the scree field leading to easier ways.
Crampons and Ice Axe recommended for the glacier, if snow covered hiking poles should suffice(or climb around it).
Helmet recommended.
