Alta Via n. 2 della Valle d'Aosta - Tappa 10

The Alta Via n. 2 della Valle d'Aosta - Tappa 10 is a 14 km point-to-point trail in the Aosta Valley, Italy, climbing from Cogne (1,545 m) to the Rifugio Sogno di Berdzé (2,530 m) and gaining roughly 990 m of elevation in a single day. Rated moderate-to-strenuous, it threads the Val di Cogne beneath the Gran Paradiso massif on classic high-mountain terrain.

About the Alta Via n. 2 della Valle d'Aosta - Tappa 10

The Alta Via n. 2 della Valle d'Aosta is one of two great high routes that trace the Aosta Valley from end to end. Where its sister trail, the Alta Via n. 1, hugs the northern slopes beneath the Matterhorn and Monte Rosa, the Alta Via n. 2 runs along the southern, sun-facing side of the valley, linking Courmayeur to Donnas across 14 daily stages. The full traverse reaches a maximum altitude of 3,299 m and crosses seven lateral valleys, including the Valle di Champorcher, Val di Cogne, Valsavarenche, Val di Rhêmes, Valgrisenche, the Vallone di La Thuile, and Val Veny.

Tappa 10 — Stage 10 — is the section that begins in the village of Cogne (1,545 m) and finishes at the Rifugio Sogno di Berdzé al Péradzà (2,530 m). It sits entirely within the Val di Cogne, one of the most beautiful side valleys of the region and a gateway to the Gran Paradiso National Park, Italy's oldest national park, established in 1922. Over its 14 km the stage climbs nearly 990 m, a sustained but rewarding ascent that delivers walkers from a lively alpine resort village into a quiet high basin ringed by peaks.

The Alta Via n. 2 shares part of its course with the legendary Tor des Géants, the 330 km ultra-endurance race that loops the Aosta Valley each September. For most hikers, though, the appeal of Tappa 10 is far gentler: a manageable single-day outing that can be walked on its own or stitched into a longer multi-day high-route adventure. The whole Alta Via n. 2 is operated and waymarked by the Regione Autonoma Valle d'Aosta, with consistent yellow-and-black signposting marked "Alta Via 2" throughout.

Route Overview & Stages

The table below places Tappa 10 within its immediate context on the Alta Via n. 2. Distances for the surrounding stages are approximate, as the official route description gives walking times (3–5 hours per stage on average) rather than precise kilometre figures.

The full Alta Via n. 2 comprises 14 stages, beginning at Courmayeur (1,224 m) in the shadow of Monte Bianco and ending at Donnas (330 m) near the valley mouth. Tappa 10 is a logical, well-supported segment because both its start and end points offer reliable accommodation and the day's profile is a single clean ascent rather than a series of cols.

Highlights & Points of Interest

• Cogne (1,545 m) — A graceful alpine village famed for its broad green meadows (the Prati di Sant'Orso), its lace-making tradition, and former iron mines. It is the principal trailhead and the social hub of the Val di Cogne.
• Gran Paradiso National Park — Italy's first national park, protecting 700 km² of high terrain and the only mountain in Italy entirely within national borders to exceed 4,000 m (Gran Paradiso, 4,061 m). The stage skirts its eastern edge.
• Vallone di Bardoney — A quiet hanging valley climbed during the stage, rich in marmots, chamois and the park's emblematic Alpine ibex (stambecco).
• Rifugio Sogno di Berdzé al Péradzà (2,530 m) — The stage finish, a welcoming mountain hut set in a high pasture basin with sweeping views back toward the Gran Paradiso peaks.
• Alpine pastures (alpeggi) — Working summer dairies along the route still produce Fontina DOP cheese, often available directly from the herders.
• Lillaz waterfalls — A short detour from Cogne, these three-tiered cascades (Cascate di Lillaz) drop around 150 m and make a popular pre-hike acclimatisation walk.
• Wildlife viewing — The Val di Cogne is one of the best places in the Alps to see ibex at close range, especially in early morning near rocky outcrops above 2,200 m.
• Tor des Géants corridor — Walking here, you follow a section of one of the world's hardest trail races, its course threading the same high terrain each September.

Best Time to Hike the Alta Via n. 2 della Valle d'Aosta - Tappa 10

The hiking season for Tappa 10 runs roughly from late June to late September, dictated by snow cover on the higher ground around the Rifugio Sogno di Berdzé and the operating dates of the staffed huts. Outside this window, lingering or early snow makes the upper sections of the climb hazardous and the refuges close.

July and August bring the warmest, most stable weather, with daytime temperatures in Cogne typically between 18 °C and 24 °C and far cooler at 2,530 m. These months are also the busiest, coinciding with Italian and European summer holidays, so huts fill quickly. June can still hold snow patches on north-facing slopes after a heavy winter, while late September offers crisp air, autumn colour in the larch forests and thinning crowds, though the first snowfalls can arrive without much warning.

The single best month is September: as of 2026 the weather is generally settled in early autumn, the heaviest summer crowds have dispersed, wildlife is active ahead of winter, and the light on the Gran Paradiso peaks is at its finest. Aim for the first three weeks before huts begin closing for the season. Whenever you go, check the latest conditions and refuge opening dates before setting out, as alpine weather can shift rapidly.

Practical Information

Accommodation

The natural endpoint of the stage is the Rifugio Sogno di Berdzé al Péradzà (2,530 m), a staffed mountain hut offering dormitory beds and meals. Expect to pay roughly €25–€30 for a dormitory bunk and around €50–€60 for half board (dinner, bed and breakfast), typical of Aosta Valley refuges in 2026. Booking ahead is essential in July and August.

In Cogne itself, the starting point, you'll find a full range of hotels, guesthouses (B&Bs) and the Cogne municipal campsite. Hotel rooms run from about €70 to €140 per night depending on season and category, while a camping pitch costs roughly €12–€20 per person. Booking a night in Cogne before the climb lets you start fresh and acclimatised.

Getting There & Back

The nearest railway station is Aosta, on the line from Turin via Ivrea and Chivasso. From Aosta, regional SVAP/Arriva buses run up the Val di Cogne to Cogne village in about 50–60 minutes. The nearest major airport is Turin–Caselle (TRN), around 2 to 2.5 hours away by road; Geneva (GVA) and Milan Malpensa (MXP) are alternative gateways at roughly 2 to 3 hours. Driving from Aosta to Cogne takes about 40 minutes via the SR47 mountain road. Returning from the Champorcher side after subsequent stages, buses connect to Hône-Bard station on the main valley railway.

Permits & Fees

No permit is required to walk the Alta Via n. 2 or to enter Gran Paradiso National Park on foot — access is free and open. Standard national park rules apply: stay on marked paths, do not disturb wildlife, camping is restricted (wild camping is generally prohibited within the park, with bivouacking tolerated only above the treeline from dusk to dawn in some zones), and dogs may be limited. Your only real costs are accommodation, meals and transport.

Gear & Packing List

Tappa 10 is a genuine high-mountain day with nearly 1,000 m of climbing, so pack for rapid weather changes: layered clothing, a waterproof shell, sun protection, sturdy boots, at least 1.5 litres of water capacity and trekking poles for the descent. If you're linking several stages, a comfortable 35–55 litre pack carries hut gear without excess bulk. The lightweight Arc Haul Ultra 50L and the rugged Abisko Hike 35 both suit hut-to-hut alpine travel, while the 2400 Windrider is a proven ultralight choice for fast-and-light traverses.
