You can hike from Lienz hut along Franz Keil Weg to what is known as the Gartl. From there, you will have the opportunity to tackle the Debantgrat (3,058 m), a mountain directly next to the eponymous mountain of Schober Group. The journey takes you from Debantgrad past Gartlsee lake and across Gartltörl to Hochschober hut, the last stop of the third stage.
