This hike in Sardinia passes through an area of great archaeological and anthropological importance and leads past four Nuraghi, megalitic structures built between 700 and 1900 BC: the Nuraghe Serbissi, Urceni, Sanu and Orruttu. The hike also passes a number of viewpoints, such as the Vedetta and Is Arenas, from where we have a nice view of Gennargentu National Park and Perda 'e Liana. The hike develops almost entirely along dirt roads and is therefore very easy to walk.
- From the junction (1) where we have parked, take the asphalt road to the right. After about twenty minutes we see on the right a signpost (2), which we ignore and stay on the asphalt road.
- After about 10 minutes at the fork (3) we turn right, towards Nuraghe Serbissi. After 10 minutes, a trail breaks off to the left (4), but we go straight ahead and keep walking on the dirt road.
- A few minutes later we turn right (5), following the signpost to the Vedetta. In 10 minutes we walk to the top of the Vedetta (6) from where we have a nice view and also see the Perda 'e Liana nicely.
- From the Vedetta we walk back to the dirt road (5) where we turn right towards Serbissi. A little further ahead in a bend (7) we ignore the signpost left to Serbissi and go straight ahead up the path.
- Just under 10 minutes further on a fork (8) we keep to the right, onto the upper path. Ten minutes later we ignore a side-path to the right (9), to a viewpoint. About 5-10 minutes later we do follow the signpost to the right (10), to a viewpoint.
- In 10 minutes we walk to Is Arenas (11) from where we have a nice view. From this viewpoint we walk back to the fork (10) where we go right. Ten minutes later at the fork (12) we keep to the right, following the signpost of the 521.
- Five minutes later (13) we turn right, towards the Serbissi. In ten minutes we walk to the entrance of the Nuraghe of Serbissi (14), which you can visit for a small fee if desired.
- From the entrance of the Nuraghe of Serbissi we walk back to the fork (13), where we turn right, further following the 521 via the dirt road. A little further down the road (15) you should not take the turn to the left, but go straight ahead. This is not marked.
- We follow the route for quite some time and after about an hour on our right we see the Cave Lioni (16). On this stretch we have a nice view from the dirt road. Ten minutes later we go left with the bend (17).
- After 20 minutes at the fork (18) we go straight ahead, to the Nuraghe Urceni (19), which lies almost directly behind the bend. After visiting the Nuraghe we walk back to the fork (18) where we turn left/go straight ahead.
- After ten minutes we come out on a dirt road (20) where we go right. More than five minutes later at the fork (21) we go straight ahead, following the signpost. Five minutes later at the Y-fork (22) we go straight ahead/left, following the signpost.
- Ten minutes later on the T-fork (23) we go straight ahead, following the signpost of the 521. Ten minutes later (24) we turn right, to the Nuraghe Sanu. A little further on we turn left (25) to reach the Nuraghe Sanu (26).
- From the Nuraghe Sanu we walk back to the asphalt road (24) where we now turn right. Further on we get to another Nuraghe, the Nuraghe Orruttu (27).
- From this last Nuraghe we simply follow the asphalt road back to the car (1).
