The G 310 B trail connects the G 310 A and the G 302 trail via a comfortable forest track that allows you to reach the rest area and the Sa Jone lake.
The trail develops between the peaks of the mountains surrounding Monte Lerno and never drops below 850 meters above sea level, crossing areas reforested with conifers which have been subject to recent forestry interventions and the forest is slowly evolving towards a mature broad-leaved forest composed mainly of holm oaks and cork oaks.
The trail allows, via the connection with the trail G 302, to reach the rest area for of Bilotze or to make a loop with the latter and the G 303 trail to return to the forest barracks in Badu Onu.
