At Valdurna – Durnholz (car park; from Bolzano, junction for Campolaste-Astfeld) we will drive along the lake; at the junction we will take route 16, going up through the forest and passing the Seebbachalm alpine hut. Walking across grazing land, mountain pines, boulders and scree we reach the Flaggerscharte Col, the lake and refuge (2,481 m, open in summer; approx. 3 hours). We will continue southwards on a marked path among boulders and scree and around the Lorenzenspitze, and eventually walk up to the cross on the summit (2,741 m, 1 hour from the refuge). Return via the same route (2.5 hours).
