FATMAP difficulty grade
This is a hike up to the Lachenspitze Nordwand Klettersteig from Vilsalpsee. At the base of Lachenspitze you can either follow the trail around and up to the summit.
This route goes up the Via Ferrata, so gear is required. At the summit you can follow the trail back around and down to join the same trail you came up on. Landsberger Hütte is a nice place for food and a beer.
