Down the Throat of Sardinia: Hiking Gorropu Canyon
A full-day descent into Italy’s deepest gorge where stone, shade, and river set the pace.
The wind at Genna Silana tastes like salt and stone. Juniper leans into the pass, its roots gripping the Supramonte as if steadying an old friend. Below, the land opens and then drops away—limestone buckles, the earth creases, and somewhere down there the Flumineddu River whispers a promise. The trail wastes no time. You step from the roadside and the mountain exhales, ushering you onto a shepherd’s path that unzips the slope in blunt, rocky switchbacks. Sardinia doesn’t coddle. It nods at your boots, measures your water, and asks if you’ve started early enough. In this light, the cliffs across the valley blush gray-blue, and you can feel the canyon calling—a narrow seam stitched through the island’s wild heart.
Trail Wisdom
Beat the Heat
Start by 8 a.m. from Genna Silana to avoid the steep exit ascent under direct sun.
Know the Zones
Inside the gorge, green/yellow/red sections mark escalating difficulty—turn around before red if you’re not confident on hands-and-feet scrambling.
Water Wins
Carry 2–3 liters per person; there are no reliable refill points on the route and heat radiates off limestone.
Footing Matters
Wear shoes with sticky rubber and firm support—polished limestone and rounded boulders reward traction and precise steps.

Conservation Note
Gorropu lies within protected Natura 2000 habitat. Stay on marked paths, respect closures, and avoid trampling rare cliff plants endemic to the canyon.
The Barbagia uplands sheltered the Nuragic civilization and later shepherds and outlaws; Gorropu’s walls have been a refuge and a corridor for centuries.
Seasonal Guide
spring
Best for: Cooler temperatures, Flowing river scenes
Challenges: Slippery rock after rain, Occasional closures due to high water
Arguably the best season—wildflowers, running water, and stable weather if you watch the forecast.
summer
Best for: Long daylight, Dry boulders and clear lines
Challenges: High heat and exposure, Crowds on popular days
Start early and bring extra water; the canyon offers shade but the approach and exit can be scorching.
fall
Best for: Mild temps, Quieter trails
Challenges: Shortening days, First rains can make stone slick
A strong second choice with fewer people and forgiving weather—watch footing after early storms.
winter
Best for: Empty trails, Crisp air for big views
Challenges: Cold shade in the gorge, Potential closures after heavy rain or rare snow at the pass
Feasible in stable weather for prepared hikers; shorter days demand an earlier start and spare layers.
Photographer's Notes
What to Bring
Sticky-Soled Hiking or Approach ShoesEssential
Polished limestone and rounded boulders demand traction and precise footwork.
Hydration Reservoir (2–3 liters) + ElectrolytesEssential
There’s no reliable water on route and heat reflects off the rock—sip steadily to avoid bonking.
Collapsible Trekking Poles
Useful for the long descent/ascent and stowing before hands-on bouldering.
Lightweight Sun Layer and HatEssential
Shade in the canyon can be cool, but approaches are exposed—versatile layers keep you comfortable.
Common Questions
How long is the hike from Genna Silana to Gorropu Canyon and back?
Plan 6–8 hours total with roughly 650–700 meters of descent and ascent; distance varies by exploration inside the gorge.
Do I need a guide for Gorropu Canyon?
A guide isn’t mandatory, but local guides add safety, route knowledge in the boulder fields, and insight into geology and culture.
Is there water available on the trail?
No reliable sources—carry 2–3 liters per person. Seasonal springs are not dependable, and water in the gorge may be inaccessible.
Are permits required to enter the canyon?
No permit is required, but there is a paid entrance managed at the canyon floor; fees support conservation and safety.
Is the canyon safe after rain?
Conditions can change quickly—slick rock and high water are hazards. Check for closures at the entrance kiosk and avoid the gorge after heavy rain.
Is Gorropu suitable for children?
Fit, older children may enjoy the green section with supervision. The red zone is not recommended for kids or inexperienced hikers.
What to Pack
2–3 liters of water with electrolytes—no reliable refills; Sticky-soled hiking shoes—limestone is polished and slick; Sun hat and high-SPF sunscreen—exposed approaches can be brutal; Compact first-aid kit with blister care—the exit climb is unforgiving if hotspots flare.
Did You Know
Gorropu is often cited as Italy’s deepest canyon, with walls reaching up to 500 meters and narrowing to just 4–5 meters in places. It hosts the critically rare Aquilegia nuragica, a columbine found on only a few cliff faces in the gorge.
Quick Travel Tips
Arrive at Genna Silana Pass early—parking is limited on peak days; Bring cash for the canyon entrance fee—card acceptance can be unreliable; Check conditions the day before—sections may close after rain; Plan a recovery swim at Cala Fuili or Cala Luna—both are an hour’s drive from the pass via Cala Gonone.
Local Flavor
Refuel Barbagia-style: try culurgiones (stuffed pasta) and roast suckling pig at a local agriturismo near Dorgali, then toast with a glass of Cannonau. For a splurge, dine at Su Gologone near Oliena—Sardinian classics in a setting that feels stitched to the limestone hills. For something casual, grab a seaside gelato and a cold Ichnusa in Cala Gonone while the Tyrrhenian cools your legs.
Logistics Snapshot
Closest airport: Olbia Costa Smeralda (OLB), ~1 hr 45 min by car. Trailhead: Genna Silana Pass (SS125). Drive time: ~50–60 minutes from Cala Gonone/Dorgali via winding mountain roads. Cell service: Spotty on the approach, generally none inside the canyon. Permits: No permit; pay entrance fee at canyon kiosk. Footwear and water are non-negotiable.
Sustainability Note
This karst landscape is fragile—stay on marked paths, do not build cairns, and pack out every crumb. Water is scarce; avoid washing gear in the river and give wildlife generous space on ledges and near the watercourse.
