So, I spent the day in the fog 😄. I might redo it some day, the all view should be amazing, the lake and foggy scenery was already great.
The Pizol 5 lakes (5-Seen-Wanderung Pizol) is super popular, therefore best during the week if you don't want to slalom between hikers.
Passing the summit was alright but snowy. Likely a trail best suited towards the end of summer.
Oh, worth noting, had no phone signal most of the day.
