Starting in Mandarfen, firstly cross the bridge towards the mountain rescue building and then turn left along the agriculture road up towards the catered mountain hut Taschachalm. Once there, continue to run in the direction of Rifflsee Lake until a path forks off to your left. Follow this path to Rifflsee Lake and keep right, then follow the signpost to the mountain restaurant Sunna Alm / top station Rifflsee gondola on the left. From Sunna Alm return down to Rifflsee Lake and follow the lakeside path around the lake, then return to the valley on the path past the Taschachalm. Once there, follow the same route as on your way up to return to your starting point in Mandarfen.
