Arrival by car: From Hermagor via the B111 (Gailtal Road) or from Oberdrauburg via the B110 (Plöckenpass Road) to Kötschach-Mauthen and from there via the B111 (Gailtal Road) continuing to Reisach. Here you turn onto the side road to the Reißkofelbad or subsequently onto the gravel road near the Jochalm.
Public transport:
The most sustainable way to get here is by train to Oberdrauburg (coming from Lienz or Villach) or to Hermagor (coming from Villach) theoretically possible.
From Oberdrauburg or Hermagor you can then reach the town of Reisach by bus. From here, you should allow about 2.5 hours extra time on foot (uphill) to reach the start of the route.
