From Olbia:
 

Dual Carrriageway Route:
Leaving the airport or coming from the port, you must take the direction towards Sassari, and after about 1 Km., take the approach ramp on the right in the direction of San Teodoro/Siniscola on the new stretch of the dual carriageway Olbia - Nuoro.
At the end of the first stretch of dual carriageway, take the direction of San Teodoro and follow the road signs for Nuoro. Having passed the exit for San Teodoro, you will get back onto the dual carriageway until reaching Nuoro.
At the outskirts of Nuoro, follow the road signs for Lanusei, and go for about 70 Kms. along the new dual carriageway.
At the end of the dual carriageway, after just having passed the built up area of Villanova Strisaili, you need to turn left in the direction of Villagrande Strisaili, driving beside the woodlands of Santa Barbara and following the road signs for Tortolì/Arbatax, you will arrive at your destination.

Panoramic Route:
In order to avoid the chaotic traffic between Olbia & San Teodoro, the first part of this route is the same as the dual carriageway route.
At San Teodoro, continue following the road signs for Orosei, where you will arrive after having passed the localities of Budoni, Posada and Siniscola.
At Orosei, follow the road signs for Dorgali, and from here continue on towards Baunei, passing through the Silana Pass and admiring the splendid mountainous scenery with the magnificent view of the Su Gorroppu gorge, close to the Tiscali Village.
After having passed Baunei, continue onwards to Arbatax, crossing through the built up areas of Lotzorai and Girasole, to arrive at your destination.
