The G 310 A trail connects the Monte Sas Crabas fire lookout with the G 310 trail which leads to Tandalò or Santa Reparata in the municipality of Buddusò. The trail winds through the hills north of Monte Lerno and offers remarkable panoramic and naturalistic glimpses. It is in fact possible to encounter herds of deer and mouflon as well as numerous species of birds of prey. The trailalso allows easy access to the area of the Monte Lerno lakes, a series of artificial reservoirs now perfectly integrated into the ecosystem and landscape which make the area particularly evocative.
