An immense green lung blanketing the mountains of the Iglesiente, spanning over three thousand hectares across the area surrounding Domusnovas and Iglesias. The Marganai Forest (Foresta del Marganai) is a wild territory defined by limestone peaks, deep canyons, and natural caves interspersed with dense forest cover. Here, a timeless mountain landscape holds sway, where the silence is broken only by rushing streams and the wind sweeping through the valleys.
The forest is crisscrossed by a dense network of trekking and mountain biking trails, many following old routes once used by charcoal burners and miners. Exploring the woods brings you face-to-face with relics of an industrial mining past—decommissioned tunnels, stone structures swallowed by nature, and historic mule tracks ascending toward scenic viewpoints.
The forest connects directly to the nearby San Giovanni Cave (Grotta di San Giovanni), serving as the natural continuation of the journey for those emerging from the famous karst tunnel. Its location also offers easy access to the historic mining complexes of Seddas Moddizzis and Monteponi, making this area an essential stop for anyone wishing to discover the inland, industrial soul of the Iglesiente.
