Italy's deepest gorge and one of Europe's most dramatic canyon hikes. The walk follows the Flumineddu river into the Gorropu gorge, where vertical limestone walls rise up to 500 metres overhead. The gorge floor involves boulder scrambling but no technical climbing is required for the accessible section.
Su Gorroppu is one of the deepest gorges in Europe, carved by the Flumineddu river through the limestone heart of the Supramonte in Nuoro Province, eastern Sardinia. The most popular approach is an out-and-back of roughly 10 kilometres with about 300 metres of elevation change, starting either from the Sa Barva bridge below the Genna 'e Silana pass on the SS125 road or from near Hotel Silana. Cars park at the trailhead, and the path descends through holm oak and oleander along the Flumineddu valley floor before reaching the gorge mouth. Inside, vertical limestone walls soar up to around 500 metres overhead, narrowing dramatically and keeping the canyon floor cool and shaded even in high summer. The walking surface shifts from dirt path to large river boulders that require careful scrambling; there is no technical climbing on the standard tourist section, though scrambling skill and sure footing are needed where the boulders grow huge. Walkers can continue only as far as the colour-coded difficulty zones allow before equipment is required. Endemic plants cling to the walls, and the deep shade makes the gorge a refuge on hot days. There are no refuge huts or shops on the route, so water must be carried, and the river can rise fast, so the gorge floor should never be entered after recent heavy rain. A small access fee is collected at the gorge by the local management cooperative, and guided trips run from Dorgali and Urzulei for those wanting interpretation or a safer first visit. The return follows the same route back up to the trailhead, a steady climb out of the valley. The combination of accessibility from a paved road, dramatic vertical scale and relatively modest distance makes Su Gorroppu one of the signature day hikes of inland Sardinia, suitable for reasonably fit walkers prepared for boulder scrambling and a warm climb back to the car.
Trail facts
- Best season
- April to June and September to October (avoid after heavy rain)
Highlights
- 500m vertical limestone walls
- Italy's deepest gorge
- Cool temperature even in summer
- Endemic plants in the canyon
- Dramatic boulder scrambling
Tips for visiting
- Do not attempt if there has been recent heavy rain — the floor floods rapidly
- wear sturdy boots and bring plenty of water
When to visit
Spring and early autumn are ideal, with mild temperatures and lower flood risk. The shaded gorge stays cool even in summer, but the exposed climb back to the trailhead is best tackled in the morning before the midday heat.
Accessibility
The descent into the gorge and the boulder-strewn canyon floor are not wheelchair- or stroller-accessible; the route involves uneven ground and scrambling over large rocks that require sure footing and sturdy boots.
Frequently asked questions
How hard is the Su Gorroppu hike?
The standard out-and-back is moderate: about 10 kilometres with 300 metres of climbing and boulder scrambling on the gorge floor. The main effort is the steady ascent back to the trailhead at the end.
Is there an entrance fee?
Yes, a small access fee is collected at the gorge by the local cooperative that manages the site. Deeper sections of the canyon are graded by difficulty and require technical equipment to pass.
Can the gorge be hiked after rain?
No. The Flumineddu river can rise rapidly and flood the canyon floor, so the gorge should not be entered after recent heavy rain. Checking conditions before setting out is essential.
Is a guide necessary?
A guide is not required for the standard tourist section, but guided trips from Dorgali and Urzulei are recommended for first-time visitors and for anyone wanting to go beyond the easy zone.
