We start our hike at Gasselhöh'-Hütte on Reiteralm and hike up the trail n° 66 to the ridge that leads us to the summit of Gasselhöhe (2,001 m). From there the trail gets easier at first with just slight ups and downs leading us towards Rippetegg. The final ascent takes to the summit of Rippetegg (2126 meters) takes us about 15 minutes.
From there we take the same way back at first and then turn off right to descend - quite steeply - to the Gasselseen Lakes. At first we reach the Obere Gasselsee where the terrain gets easier again. In a couple of minutes we further hike down to the Mittlerer Gasselsee - the infamous "Spiegelsee Lake" (Mirror Lake).
From there a broad trail leads us back to our starting point at the Reiteralmsee reservoir
Variant via Untersee Lake
About halfway from Spiegelsee Lake you may turn-off towards Untersee Lake and walk back along the theme trail "Silent Waters" (it will take you an additional 30 to 40 minutes).
