Arrival by car: Take the B111 (Gailtal Road) to Tröpolach - from there take the B90 (Nassfeldpass Road) towards the state border. 300 m before the border, turn right off the B90 towards the valley station of the Madritschenbahn.
Alternatively, in Tröpolach, you can turn right from the B90 onto the parking lot at the valley station of the Millenium Express.
Public transport:
The most sustainable travel option is theoretically by train (coming from Villach) to Hermagor. From Hermagor, you can continue by bus to the town of Tröpolach.
Alternatively, there is also the possibility to travel by bus from Kötschach-Mauthen or Villach to Hermagor or Tröpolach.
From Tröpolach, take the Millennium Express up to the mountain station – this is located very close to the mountain station of the Madritschenbahn. From here, you descend with the Madritschenbahn to the starting point of your hike.
