The easiest route leads from the Wiesbadener hut (2443 m) in Vorarlberg over the Buinlücke (Fourcla Buin) and the west ridge to the summit. The Piz Buin Pitschen can also be climbed from the Chamonna Tuoi (2250 m) in the Swiss Tuoi valley over the glacier La Cudera and Fourcla dal Cunfin or the Vermuntpass.
