The G 504 B trail starts in the locality of Su Corriadore in correspondence with the G 504 A trail and develops south of the rock formation, proceeding downhill for almost the entire length.
Along the trail the trail comes across the characteristic granite formation known as "the dancing rock" made up of an enormous boulder that seems to be in a precarious balance, and the remains of the nuragic village of Sedda Ottinnera where the trail rejoins G 504 trail.
