Great pictures Sebastian, and really good info!
Under "related trips" you could add this one. We took a trail down from the Alpspitze to drink an Apfelschöle in the Höllentalangerhütte during a lightning storm:
The trail was really pretty as you are looking down at the Höllentalklamm and across to the Zugspitze.
and good and overall informations! It´s really a beautiful hut!
