How to get there:
Leaving Cagliari, take the coastal road towards Villasimius. Once you reach Solanas, turn left on the road for Castiadas, which runs along the Rio di Solanas River. Before you reach Castiadas, once you get to Gutturu Frasca, turn left. At the end of the road turn right towards Monte Arbu, and you will immediately reach the Sphinx.
Attention!
The monument is inside the Castiadas State Forest: it is not easy to reach, and if you do not know the area, we suggest you ask for a guide.
