Arrival by car: Take the B100 (Gailtal Road) to Tröpolach - from there take the B90 (Nassfeld Pass Road) to Nassfeld Sonnenalpe or further towards Nassfeld Pass and follow the signposts to Almresort (turn left - after the valley stations of the Gartnerkofel and Tröglbahn).
Public transport:
The most sustainable travel option is by train (coming from Villach) to Hermagor. From Hermagor, you can then reach the town of Tröpolach by station shuttle, as well as bus / ski bus.
Alternatively, there is also the possibility to travel by bus from the direction of Kötschach-Mauthen or Villach to Hermagor or Tröpolach.
From Tröpolach, take the Millennium Express up before reaching the starting point of your winter hike via the downhill piste or the descent with the Madritschenbahn (approximately 20 more minutes on foot from the Madritschenbahn valley station).
