Departing from Cagliari, drive for 2 hours in a minivan through the amazing Sardinian countryside towards the northwest of the island. This is a full-day private tour to discover the nuraghe of Santu Antine (San Costantino) in Torralba. The complex is one of the best preserved nuragic architectures and with a mere labyrinthine interior. Visit the Domus de Janas "Fairy Houses" of Sant'Andrea Priu, collective burials of the Neolithic period. The tour will then approach the charming town of Bosa, dominated by the castle of Malaspina, with its colorful architecture and crossed by the river Temo, the only navigable river in Sardinia.
