A truly high level location easy to get to
from 5/1/19 to 6/1/19 cableway doesn’t work. So you can get the Hostel only along the road.
By car via Autostrada A24: take A24 until you get to Assergi toll booth; then continue on SS 17bis to Fonte Cerreto (funicular departing station) and Campo Imperatore and keep going on Ss 17BIS C until you arrive to the hostel (cableway arrival station).
In spring and summer you can get to the hostel by car simply following the road signs from Fonte Cerreto to Campo Imperatore.
