Nature lovers have the chance to explore the stunning views of the Italian region of Sardinia by embarking on a 500km trail in the southwest of the island. The trail, known as the Cammino Minerario di Santa Barbara (Santa Barbara's Mining Trail), is made up of 30 stops steeped in history and culture.

And for visitors under 35, the autonomous region of Sardinia set up a system allowing them to stay at local hotels and B&Bs almost entirely for free. To help attract younger tourists, affiliated businesses are accepting symbolic donations in exchange for accommodation along the whole trail.
