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.

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.

Or the Menhir of Terrazzu (the location where it is located). A megalithic monument over 5 meters tall; its current height, however, is not its original height, as its top was damaged by lightning. It is said that it was planted in Terrazzu by the giantess Luxia, who was tasked with building a bridge between the island of Sant'Antioco and the mainland. Upon arriving, however, she saw that the bridge had already been built and, enraged, threw the boulder to the ground, where it can be seen today. In the small park where the menhir is located, there is also a bicycle repair and maintenance station sponsored by the Cammino di Santa Barbara, of which the monument is part.

The Nuxis area offers a selection of dedicated no-traffic gravel bike trails, with at least two challenging routes detailed in this guide. These routes are designed to immerse you in the region's natural beauty away from busy roads.
You'll encounter a diverse range of terrain, from rugged mountains and rolling hills to unpaved roads and old mining tracks. The region, particularly near Monte Tamara and the Monte Arcosu Wildlife Sanctuary, features varied topography with challenging climbs and scenic stretches through vast forests and mountains, offering a true sense of wilderness.
While many trails in the Nuxis area, especially those listed in this guide, are rated as 'difficult' due to significant elevation changes and distance, there is an 'easy' route available: the Porto Botte – Porto Botte Beach loop from Giba. This route offers a gentler experience, suitable for families looking for a less strenuous ride.
The region is rich in history. You can explore sites like the Rosas Mining Village Narcao, an eco-museum offering insight into the area's mining past. Other notable historical points include the Nuragic Sacred Well of Tattinu and the ancient rural Church of S. Elia in Nuxis, as well as the prehistoric Montessu Necropolis.
Yes, several routes in the Nuxis area are designed as circular loops, allowing you to start and end at the same point. Examples include the challenging San Giovanni Cave – Sa Reina monumental olive tree loop from Narcau/Narcao and the Porto Botte – Porto Botte Beach loop from Giba.
Sardinia generally offers pleasant conditions for outdoor activities for much of the year. Spring (April-May) and Autumn (September-October) are often ideal, with milder temperatures and less rainfall, making for comfortable riding conditions. Summers can be very hot, while winters are generally mild but may see more rain.
The no-traffic gravel bike trails around Nuxis offer a range of difficulties. While there is an 'easy' coastal route, many of the inland trails, such as the Sa Reina monumental olive tree – Caves of Is Zuddas loop from Narcau/Narcao, are rated as 'difficult' due to their significant distances (over 100 km) and considerable elevation gains (around 1500 meters), making them suitable for experienced riders.
Parking availability varies by starting point. For routes originating from towns like Narcau/Narcao or Giba, you can typically find parking in or near the village centers. It's advisable to check local parking regulations and designated areas upon arrival, especially in smaller communities.
While Nuxis and surrounding towns have some public transport connections, accessing specific trailheads directly by public transport can be challenging due to the rural nature of many routes. Planning your trip with a combination of public transport to a main town and then cycling to the trailhead is often the most practical approach. Always check current bus schedules for the Sulcis region.
Yes, towns like Nuxis, Narcau, and Giba offer basic amenities including cafes and restaurants. The Rosas Mining Village Narcao also functions as an eco-museum with accommodations, a restaurant, and a bar, making it a great stop or base for exploring the trails in that area. Always carry sufficient water and snacks, especially on longer routes, as services can be sparse between villages.
The trails offer stunning natural beauty. You'll pass through the expansive Oasi del Cervo e della Luna – Monte Arcosu Wildlife Sanctuary, home to the largest Mediterranean forest and diverse flora and fauna, including the Sardinian deer. Look out for the ancient Sa Reina monumental olive tree, and enjoy panoramic views from various points along the mountainous routes.
Absolutely. The Nuxis area is ideal for experienced gravel bikers seeking a challenge. Routes like the Sa Reina monumental olive tree – Caves of Is Zuddas loop from Narcau/Narcao, spanning over 100 km with significant elevation, provide a demanding yet rewarding experience through the rugged Sardinian landscape, largely on quiet mountain trails and unpaved roads.
While specific regulations for dogs on all gravel trails may vary, generally, dogs are welcome on many outdoor trails in Sardinia, provided they are kept under control, especially in natural areas like the Monte Arcosu Wildlife Sanctuary. Always ensure your dog is on a leash where required, and be mindful of wildlife and other trail users. Remember to carry water for your pet and clean up after them.
