This route passes through places of particular natural and archaeological interest such as the Country shrine of San Costantino.
The Shrine houses nuragic sculptures, called perdas fittas, believed to represent a female deity. As it is quite close to Lake Omodeo, the route offers some splendid viewpoints along the way. The trail starts in at Su Frontigheddu, which is also the starting point of the thrilling equestrian event, the Ardia, and ends at Su Pranu. The trail is a branch-off of trail G-611.
