Leaving the village of Rebeccu heading west, the trail proceeds along the G 601 B trail which abandons by turning left onto the G 601 A trail which constitutes a junction of just under 400 meters which leads about half its length to the nuragic spring of Su Lumarzu. The trail continues for a further 200 meters and rejoins the main trail (G 601) in Cantaru Addes from which it is possible to continue to the Mariani Service Center or return to the village of Rebeccu, thus forming a small circular route.
