Alta Via n. 1 della Valle d'Aosta - Tappa 16

The Alta Via n. 1 della Valle d'Aosta - Tappa 16 is an 8 km point-to-point high-alpine trail in the Aosta Valley of north-western Italy, linking Rifugio Frassati (2,540 m) to Rifugio Walter Bonatti (2,025 m). It gains roughly 400 m of climbing over a single day, crossing the Col Malatra at 2,925 m. Rated moderately difficult (E/EE), it delivers some of the route's finest Mont Blanc panoramas.

About the Alta Via n. 1 della Valle d'Aosta - Tappa 16

The Alta Via n. 1 della Valle d'Aosta — nicknamed the Alta Via dei Giganti, the “Route of the Giants” — is a long-distance high mountain traverse that runs the length of the Aosta Valley's northern flank, from Donnas (329 m) in the east to Courmayeur (1,223 m) beneath Mont Blanc. The whole itinerary covers roughly 150 km and is broken into a series of stages between manned refuges. Under the official numbering published by the Regione Autonoma Valle d'Aosta, Tappa 16 is the penultimate high-mountain segment: an 8 km crossing from Rifugio Frassati to Rifugio Walter Bonatti.

This stage is short on the map but big on character. Starting at Rifugio Frassati (2,540 m) in the wild Vallone di Malatra, the path climbs steadily to the Col Malatra (2,925 m) — the highest point on the entire Alta Via n. 1 — before dropping into the celebrated Val Ferret. The descent ends at Rifugio Walter Bonatti (2,025 m), a balcony hut that also sits on the Tour du Mont Blanc circuit. Because it bridges the remote Saint Bernard side of the valley with the Mont Blanc massif, Tappa 16 is where the “Giants” of the route name — Mont Blanc, the Grandes Jorasses and Mont Dolent — finally fill the horizon.

The trail is operated and waymarked by the Regione Autonoma Valle d'Aosta with the distinctive Alta Via triangular markers (yellow with a black “1”). The pass section is rocky and exposed, with fixed chains in places near the col, which is why the grade nudges from E (intermediate) into EE (experienced) terrain. For most fit walkers it is a half-day of around 4 to 5 hours, often combined with the final stage down to Courmayeur to finish the Alta Via in style.

Route Overview & Stages

Tappa 16 is a single stage, but it helps to see it in the context of the surrounding segments of the Alta Via n. 1. The table below breaks the stage into its natural sections and shows how it connects to the legs on either side.

The climb to the col accounts for almost all of the day's ascent, so the effort is front-loaded; once you crest the Col Malatra the trail is a long, scenic descent and traverse into the Val Ferret. The previous stage arrives at Frassati from the direction of the Col du Grand Saint-Bernard, and the following final leg drops from Rifugio Bonatti down to Courmayeur in around 3 to 4 hours.

Highlights & Points of Interest

• Rifugio Frassati (2,540 m) — the stage's starting hut, named after Pier Giorgio Frassati, sitting in the lonely upper Vallone di Malatra below the Mont Gelé group.
• Vallone di Malatra — a stark, glacially shaped side valley of rock and short-grass pasture, often holding snow into early summer.
• Col Malatra (2,925 m) — the highest point on the whole Alta Via n. 1, reached through a narrow rocky notch fitted with fixed chains; the panorama opens suddenly onto the Mont Blanc massif.
• Grandes Jorasses (4,208 m) — the great granite wall that dominates the descent, with the Walker Spur clearly visible across the Val Ferret.
• Mont Dolent (3,820 m) — the peak where the Italian, French and Swiss borders meet, framed at the head of the valley.
• Alpe Sécheron & Malatra alps — working high pastures where marmots and chamois are common sightings on the traverse.
• Rifugio Walter Bonatti (2,025 m) — the stage's end, a modern eco-friendly hut named after the legendary alpinist, famous for its terrace facing the Mont Blanc giants.
• Val Ferret — the glacial valley that the Bonatti overlooks, also walked by hikers on the Tour du Mont Blanc.

Best Time to Hike the Alta Via n. 1 della Valle d'Aosta - Tappa 16

The viable season for this stage is short. Because the Col Malatra sits at 2,925 m, snow lingers on its northern approach well into the early summer and returns with the first autumn storms. The practical window runs from late June to late September, and the refuges that anchor the stage — Frassati and Bonatti — are generally staffed only within that period.

The single best month is August. By then the col is normally clear of snow, the fixed-chain section is dry, daytime temperatures at hut altitude sit around 12–18 °C, and both refuges are fully open with the most reliable transport in the valleys below. For 2026, expect the huts and the seasonal Val Ferret bus service to be operating across the core July–September window, with August the safest bet for settled high-pressure weather. July is a strong second choice but can hold residual snow on the col after a heavy winter, while early-to-mid September trades a little warmth for emptier trails and crisp visibility.

Whatever month you pick, start early. Afternoon thunderstorms are common over the Mont Blanc massif in mid-summer, and the col is an exposed, lightning-prone spot you do not want to be crossing after midday. Always check the regional avalanche and mountain bulletin before committing, as conditions on a 2,925 m pass can change quickly.

Practical Information

Accommodation

Tappa 16 is bookended by two manned refuges, and you will almost certainly sleep in one of them. Rifugio Walter Bonatti (2,025 m), the end point, is a modern hut where a dormitory bed typically costs around €30–35 per night, with half board (dinner, bed and breakfast) in the region of €65–75 per person — reservations are essential in August. Rifugio Frassati (2,540 m), the start, offers similar dormitory rates of roughly €28–34 per bed and half board around €60–70. Down in the Val Ferret near Courmayeur you will also find campsites and guesthouses, with pitches from about €12–18 per person and simple B&B rooms from €70 a night. Wild camping is restricted in the Aosta Valley, so plan to use the huts. Carrying your own food between huts keeps costs down — if you are calculating rations, our guide on how many calories you need hiking a full day helps you pack the right amount.

Getting There & Back

The natural base for this stage is Courmayeur, the resort town at the foot of Mont Blanc. The nearest mainline railway station is Pré-Saint-Didier (about 5 km away), connected onward to Aosta and the national rail network; coming from afar, Aosta station is roughly 35 km from Courmayeur with regular SAVDA/Arriva buses making the trip in about 1 hour. The closest major airport is Turin (Caselle), around 2 to 2.5 hours by road, with Geneva also feasible via the Mont Blanc tunnel in a similar time. To reach the trailheads, take the seasonal valley bus up the Val Ferret from Courmayeur toward Arnouvaz/Lavachey (about 30–40 minutes), from where marked paths climb to both Rifugio Bonatti and the higher Frassati. Service is summer-only, so confirm timetables before you travel.

Permits & Fees

No permit is required to walk Tappa 16 of the Alta Via n. 1 — the route is free and open to the public. Your only fixed costs are refuge accommodation, meals and the seasonal Val Ferret bus (a few euros each way). There is no park entrance fee for this section. The trail authority's full stage descriptions and updated hut contacts are published by the Regione Autonoma Valle d'Aosta on its official portal: lovevda.it Alte Vie database. For real-time weather, snow and avalanche bulletins on the high passes, consult the regional mountain-safety service at Fondazione Montagna Sicura.

Gear & Packing List

This is a short stage on paper, but it is genuine high-mountain terrain: a 2,925 m col, fixed chains and fast-changing weather. Pack accordingly. Essentials include sturdy B-grade hiking boots with good ankle support, trekking poles for the steep descent into Val Ferret, a warm mid-layer and a windproof shell (the col is cold and exposed even in August), sun protection, at least 1.5–2 litres of water capacity, and a headtorch in case of delays. Because you are moving hut to hut, you do not need a tent or much food, so a lightweight 30–40 litre pack is ideal.

For a comfortable, low-volume load, a frameless ultralight pack like the Hyperlite Mountain Gear 2400 Windrider carries a hut-to-hut kit with ease, while the slightly larger 3400 Windrider suits those who want to add a sleeping bag liner and extra layers. If you prefer a structured pack with a hip belt for the steep ground, the Fjällräven Abisko Hike 35 is a durable 35-litre option. For a deeper comparison of featherweight carries, see our roundup of the best ultralight backpacks of 2026. You can build and weigh your own version of this kit in the HikeLoad gear tool before you leave.
