From the Preintalerhütte and Waldhornalm you first follow path #777/#702 (Schladminger Tauern Höhenweg and long-distance hiking trail 02) towards Klafferkessel into the outer Lämmerkar cirque. Here you turn left and continue to follow path #777 uphill through the Innere Lämmerkar. You climb over stony ground and partly loose boulders over a steep step to Lake Kapuzinersee - an impressive summit scenery all around you.
Past the Kapuzinersee you climb south of it to the Waldhorntörl, which enables the transition to Lungau. Directly on the gap, the path branches off to the left to the summit of the Waldhorn (2,702 m). Mountain enthusiasts with good stamina and sure-footedness can integrate the summit into the tour: At the beginning there are easy climbing passages (UIAA I) to the west ridge of the Waldhorn, where the path now winds up to the highest point. The view on the climb and from the summit is magnificent.
From Waldhorntörl you now descend towards Lungauer Klafferseen. First you reach the Angersee and shortly afterwards the Zwerfenbergsee. On its southern bank, path #793 branches off towards Kleinsölktal. Now it goes uphill again, but without any major difficulties. You will soon reach the Kaiserscharte, which at 2,298 m above sea level is the highest point on the tour.
From now on it's all downhill along a well-maintained hiking trail. Past a small hunting lodge and through extensive mountain pine fields you descend into the Kaisergraben until you finally reach the Putzentalalm.
