Starting point: car park just before Plangeroß. Walk by a path, which starts off wide before narrowing and becoming increasingly steep – through the forest to the Plangeroßalpe. Once there, cross over the river at two points, continuing next to ascend on the moderately steep path along the river to the second plateau, where the path is joined by a high-level trail, the Cottbuser Höhenweg. From there, follow the trail over loose stones and rocks to the last very steep ascent of the route up to one of the highest catered mountain huts of the Ötztal Alps, the Kaunergrathütte (2,817 m). Descend by the outward route. For experienced and fit mountaineers, there is an alternative descent from the Kaunergrathütte via the Mittelberglesee lake to Trenkwald (this alter -native descent adds another 2 hrs walking time to the high Alpine trek). 

Tip: From the Kaunergrathütte, within about an hour, you can also climb the summit 
to enjoy beautiful panoramic views of the Plangeroßkopf. Grade: moderate

The start of the walk is at the hamlet Krabichl between Leins and Wald. Follow the forest path on the right to the next fork. Then follow the forest road in the direction of the Hilterboden Chapel. The forest road leads to a steep path up to the catered mountain hut Leiner Alm. Just overlooking Leiner Alm a path forks off to the left in the direction of Leiner Kögele/Sechzeiger. Return from Sechzeiger down to the catered mountain huts Kalbenalm and then on to Leineralm. From there, return via a forest road back down to your starting point in Krabichl.

From the starting point you walk along the forest path to the catered mountain hut Kielebergalm. Continue on a path, at times steep, through Wildkar cirque until you reach a fork, turn off to the right in the direction of the Schweinelieger peak. Once there, you may either take a right to walk straight to the catered mountain hut Aifner Alm or a left to climb the Kleine Aifnerspitze peak (very nice vista). Return by the same route to the Schweinelieger and descend on a well-signposted steep path to the Aifner Alm. From there, a 
waymarked steep path joins with a forest road. After a few meters on the forest road turn right to walk on a steep path in the direction of the Harbeweiher pond/Bärenbad. At the pond, take a right to return via Lachwies to Piller/Forstgarten.

Follow the agricultural road from Rehwald to the catered mountain hut Mauchele Alm. From there turn off on a trail towards Lake Brechsee which you will reach within 1 hour from the hut. It is another 1 hour 30 minutes walk to Lake Krummersee. After 50 minutes you reach the Lake Kugletersee. Return to the start via the same route.
