If you're not in a rush, one of the best ways of exploring Sardinia's rugged interior is by taking the narrow-gauge Trenino Verde. There are six available routes: Mandas–Isili–Sorgono, Mandas–Seui, Arbatax–Gairo, Macomer–Bosa, Sassari–Tempio–Palau and Palau–Tempio.

From the metro station on Piazza Repubblica in Cagliari, a metro runs to Monserrato where you can connect with trains for Mandas.
