No special access issues
FURTEI: from the town of Furtei take the road "Via San Narciso" and follow it out of town. If you drive a low vehicle park it at the end of the tarmacked road, otherwise you can continue on the dirt road and park where the road gets wider. You'll see the crag on your left-hand side. Many trails are going up the hill to the crag. Can't miss it.
SEGARIU: pass Furtei in the direction of Segariu. Just before the town, there is a junction with a sharp right turn to the right (uphill). Park your car at the second bend, near the end of the road. The crag is above you, find a path following a dirt track to the right.
