Alta via n. 6 delle Dolomiti - X tappa

The Alta via n. 6 delle Dolomiti is a 180-km point-to-point trail in the eastern Dolomites of Italy, gaining roughly 19,000 m of cumulative elevation across 11 stages. Rated moderate, it crosses ten mountain groups between Sappada and Vittorio Veneto and is nicknamed the "Alta Via dei Silenzi" for its profound, depopulated wilderness.

About the Alta via n. 6 delle Dolomiti - X tappa

The Alta via n. 6 delle Dolomiti, known in Italian as the Alta Via dei Silenzi ("High Route of Silences"), is one of the wildest and least-trafficked of the classic Dolomite high routes. Stretching 180 km from Sappada in the Province of Udine to Vittorio Veneto in the Province of Treviso, it threads through the Carnic Alps and the Friulian and Venetian Dolomites at an average elevation near 2,000 m. The full traverse is broken into 11 numbered stages (tappe), and the tenth stage — the X tappa — runs from the Ricovero Col Nudo to the Rifugio Semenza, a 6.3-hour leg gaining 1,200 m and losing 1,300 m across the rugged Alpago massif.

The route was conceived in 1972 by the alpinist Toni Sanmarchi, who named it for the silence that settled over these valleys after decades of rural depopulation. As Sanmarchi himself observed, the environment here is "truly and wonderfully solitary and wild." Unlike the busier Alta Via n. 1 or n. 2, you can walk for hours on the n. 6 without meeting another hiker, passing abandoned casere (pasture huts), dismantled military mule tracks and silent karst basins. The trail is waymarked with blue triangles bearing the number "6," supplemented by the older red-and-white blazes of the Club Alpino Italiano (CAI).

This is not a beginner's outing. Long stretches separate one shelter from the next, several stages exceed eight hours, and Stage 7 follows a partly dismantled path that requires Grade II rock scrambling. Hikers who take it on should be fit, experienced on exposed alpine terrain and comfortable with self-sufficiency. In return, the Alta Via n. 6 offers a genuine sense of remoteness that is increasingly rare in the modern Dolomites.

Route Overview & Stages

The Alta Via n. 6 is divided into 11 official stages linking rifugi (staffed huts) and bivacchi (unstaffed bivouac shelters). The table below summarises each leg, with the X tappa — the focus of this guide — highlighted within the wider traverse.

Across all 11 stages the cumulative ascent reaches roughly 19,000 m — comparable to climbing from sea level to the summit of Everest more than twice. The X tappa alone, traversing the Col Nudo–Cavallo group of the Alpago, packs a stiff 1,200 m of climbing into its 6.3 hours, making it one of the more demanding legs of the second half.

Highlights & Points of Interest

• Sorgenti del Piave (Source of the Piave) — The trail begins near the springs that feed the Piave, one of Italy's most historically significant rivers, beneath the Monte Peralba.
• Sappada — A Germanic-speaking alpine village at around 1,250 m, the last large settlement before the wilderness, known for its wooden Carnic architecture.
• Spalti di Toro & Monfalconi — A dramatic cluster of dolomite towers and pinnacles crossed around Stage 5, beloved by climbers for their isolation.
• Duranno massif — Reached on Stage 7, where the route follows a dismantled CAI path and demands Grade II scrambling on solid rock.
• Cimolais — A tiny Friulian village inside the Dolomiti Friulane Natural Park, the only mid-route resupply point of real substance.
• Col Nudo (2,471 m) — The highest peak of the Alpago group, dominating the X tappa with karst slopes and sweeping views toward the Adriatic.
• Rifugio Semenza — A welcoming staffed hut at around 2,020 m below the Cavallo ridges, marking the end of the X tappa.
• Vittorio Veneto — The historic Veneto town where the trail finishes, descending more than 2,000 m from the high Alpago to the plains.

Best Time to Hike the Alta via n. 6 delle Dolomiti - X tappa

The viable hiking window for the Alta Via n. 6 runs from late June to mid-September, when the staffed rifugi are open and the high passes are clear of snow. The single best month is July, when long daylight, stable high-pressure spells and fully operational huts combine to give the most reliable conditions for the high, exposed sections such as the X tappa across the Col Nudo–Cavallo group.

Early summer (late June) can still hold snow in north-facing couloirs and on the Grade II scramble of Stage 7, so an ice axe may be prudent in a late-melt year. August brings the warmest temperatures and the most settled weather, but also the highest risk of afternoon thunderstorms — start each stage early and aim to clear ridgelines by midday. As of 2026, hut operators in the Dolomiti Friulane and Alpago areas continue to recommend booking ahead and checking conditions, as some bivouacs and water sources can be unreliable in dry spells. September offers crisp air, thinning crowds and excellent visibility, but huts begin closing in the second half of the month, and the long final descents grow icy at dawn. Winter and shoulder-season attempts are for experienced ski-mountaineers only.

For temperatures and snow trends, consult the regional alpine forecasting service of ARPAV (Veneto Regional Environmental Agency) before committing to a multi-day weather window.

Practical Information

Accommodation

The Alta Via n. 6 is a hut-and-bivouac route. Staffed rifugi such as De Gasperi, Giaf, Padova and Semenza offer dormitory beds, hot meals and drinks; expect roughly €25–€35 for a dormitory bunk and €55–€75 for half-board (dinner, bed and breakfast) in the 2026 season. CAI members and reciprocal-club holders receive discounts of around 50%. Several legs — including the approaches to the X tappa — rely on unstaffed bivacchi like Greselìn and the Ricovero Col Nudo, which are free but provide only basic bunks and no food, water or warden. Carry a sleeping bag, stove and provisions for these nights, and always reserve staffed huts by phone in advance, as capacity is limited and the route's remoteness makes a missed bed serious. Wild camping is restricted in the protected park zones; pitch discreetly only above the tree line and leave no trace.

Getting There & Back

The northern trailhead is reached via Sappada. The nearest railway stations are Calalzo di Cadore and Carnia–Tolmezzo, each roughly 1–1.5 hours from Sappada by regional bus. From Venice Marco Polo Airport (VCE), allow 3–3.5 hours by car or a combination of train and bus to reach Sappada. The southern finish at Vittorio Veneto sits on the Venice–Calalzo railway line, with direct regional trains to Venice in about 1 hour 15 minutes, making the end of the route very easy to leave. Plan transport with the regional operator Trenitalia, and verify mountain bus timetables seasonally, as some lines run reduced services outside July and August.

Permits & Fees

No permit is required to walk the Alta Via n. 6, and the trail itself is free to access. Sections cross the Dolomiti Friulane Natural Park, where standard park rules apply — stay on marked paths, no fires, no littering — but there is no entry fee for hikers. Your only costs are hut stays, meals and transport. Budget travellers using bivouacs and carrying their own food can complete the route far more cheaply than on the busier, hut-dependent Alte Vie.

Gear & Packing List

Because the Alta Via n. 6 mixes staffed huts with unstaffed bivouacs and exposed Grade II terrain, your pack must balance light weight with genuine self-sufficiency. A 50–60 litre pack is the sweet spot for carrying a sleeping bag, stove and several days of food between resupplies. The 2400 Windrider suits faster, hut-leaning itineraries, while the larger 3400 Windrider or the load-hauling Arc Haul Ultra 60L give the volume needed when you string several bivouac nights together. For a more supportive harness on the big 1,600 m+ climbs of Stages 9 and 10, the Atmos AG 50 is a comfortable choice.

Essentials include sturdy B-rated hiking boots, trekking poles for the long 2,000 m+ descents, a 3-season sleeping bag for the bivouacs, a compact stove, a 2-litre water capacity (sources are sparse on the X tappa), waterproof shell and insulation, a helmet for the scrambling sections, a headtorch and a paper map plus GPS track.
