Not every perspective will look familiar, even to those who already know the area!
As far as the Rinnensee, the path is easily manageable even for less experienced mountain hikers – the summit climb to the Rinnenspitze, however, requires sure-footedness and a head for heights! Most of the summit section is equipped with fixed safety cables.
From the hut you should allow about 3 hours for the ascent of the Rinnenspitze!
