The G 303 trail connects the G 302 with the Sas Crabas fire lookout at Sa Mela passing, through the forest barracks and rest area of Badu Onu where there is a charging and maintenance point for E-bikes, as well as Fo.Re.S.T.A.S. service center.
The trail starts from the Sa Mela region and continues downhill until reaching the Badu Onu rest area.
Here the trail intersects the G 303A trail and takes a 2.5 km long climb that leads to the Monte Sas Crabas lookout. Once it reaches the top of Monte Sas Crabas it is easy to access the panoramic points and at the lake and the rest areas of Monte Lerno.
