From the Preintalerhütte and Waldhornalm you follow path #784 to the Sonntagskarseen. After just over an hour you will reach the lower of the two lakes, which lie in the middle of an impressive mountain basin. The path continues on the north bank of the lake and a good half an hour later you reach the Oberer Sonntagskarsee. From there, past the east bank, you climb the gravelly path to the striking cut of the Rettingscharte. The view down to the Schwarzensee in the Kleinsölktal is magnificent. Now it goes downhill into the Steinigboden until you finally reach the Schwarzensee at the waterfall near the Schwabalm.
At the southern tip of the Schwarzensee, the forest path branches off to the right to the Putzentalalm. If you want, you can hike there directly. In any case, we recommend that you spend a while at the lake and take a walk around the lake, past the Harmeralm and the Jägeralm. Great photo opportunities included! Along the forest path you can reach the Putzentalalm from Schwarzensee in about 45 minutes.
