Starting from the valley head in San Maddalena/Val Casies Valley (1460m, refreshment point, parking), turn right over the stream of the valley and follow the markings no. 12 up to the Pfoital Valley and the alpine tree line. Continue straight into the valley to the Pfoialm (2134m, not a refreshment point) and through the Almtal, on a comfortable road, uphill to the fork. There, turn right, and by following the markings no. 13 climb upwards into the rear Hintere Gsieser Lenke (2539 m; beyond it, reach the lake Schwarzsee in just a few minutes via a trail (2455m). From the lake Schwarzsee, follow the trail no. 12 (Bonner Höhenweg) and then turn into the forking climb tracks (marked), southwards, continue over rocky and grassy terrain and finally over boulders reach the Riepenspitze (2774m). Return: From the summit, follow the markings no. 47, initially along the edgy northwest ridge, then the steep western side and finally across pastoral terrain down to the Stumpfalm (2001m, refreshment point). Still on path no. 47, continue on the serpentine forest road through beautiful woods all the way to the head of the valley and San Maddalena.
