Known as the Sulcis Railway, this narrow-gauge line was built in the 1920s by the Ferrovie Meridionali Sarde (Sardinian Southern Railways) to connect the mining areas of Sulcis with coastal towns and ports of embarkation. The route passed through isolated landscapes and wooded valleys, serving villages and mines that are now partly abandoned. Today, bridges, tunnels, and disused stations remain, testifying to the era when the railway was the main means of communication for miners and goods in the southwest of the island.

A site of industrial archaeology right on a beautiful coastline. Buggerru was founded in 1864 as a mining village. Today it is a holiday resort with around 1,000 inhabitants, a fifth of what it had at the beginning of the 20th century. The present village, with the parish church dedicated to St. John the Baptist, consists of fan-shaped houses where the valley of Monte Caitas flows into the sea, a channel that gave its name to the Malfidano mine, the most important mine during the mining era from the second half of the 19th century to the beginning of the 20th century. It was active until 1979: in just over a century, Buggerru, already known for its silver in Roman times, produced more than 1 million tons of zinc and 200,000 tons of lead. Its modern small port lies beneath the exit of the Henry Tunnel, now an open-air museum, once a railway tunnel for the transport of extracted minerals.

The Rosas Mine, active from 1849 to 1980 for the extraction of silver-bearing galena, lead, and zinc, is now a multi-purpose museum that chronicles the mining history of the Sulcis region. A guided tour allows access to the underground tunnels and a close-up look at the restored structures, while nearby hiking trails allow visitors to explore the natural environment and traces of the mining activity.

Given the challenging terrain and varied conditions, it's recommended to pack essentials such as a repair kit, plenty of water, snacks, and appropriate sun protection. Depending on the season, layers of clothing are advisable. For longer rides, consider carrying a portable charger for your phone and navigation device. Always check the weather forecast before heading out.
While many outdoor areas in Sardinia are dog-friendly, it's important to consider the difficulty and length of the gravel bike trails.
