For me one of the most beautiful places in the Pfunderer mountains. The view of the Wilde Kreuzspitze from the meadow plateau around the lake is worth the effort of the ascent.
The hike to the Marblsee is steep, but it is definitely worth it. Once you reach the top, a wonderful silence awaits you in a unique landscape. You can descend to the Labisebenalm or continue hiking to the Wilden See and there is still more to do if you want and can. For example, up to the Rautalscharte, further to the Wilden Kreuzspitze or from the aforementioned gap down to the Brixner Hütte, a lovely long circuit.
