Alta Via n. 1 della Valle d'Aosta - Tappa 5

The Alta Via n. 1 della Valle d'Aosta - Tappa 5 is an 18 km point-to-point trail in the Valle d'Aosta region of northwest Italy, climbing roughly 900 m from Niel (1,550 m) over a high alpine col before descending to Gressoney-Saint-Jean (1,405 m). Rated E (escursionistico), it is a moderate full-day stage with sweeping views toward the Monte Rosa massif.

About the Alta Via n. 1 della Valle d'Aosta - Tappa 5

The Alta Via n. 1 della Valle d'Aosta — nicknamed the Alta via dei Giganti ("High Route of the Giants") — is a 14-stage trekking route that traverses the entire northern flank of the Aosta Valley, linking Donnas (329 m) in the east with Courmayeur (1,223 m) at the foot of Mont Blanc. Operated and waymarked by the Regione Autonoma Valle d'Aosta, the full traverse passes beneath three of the most famous mountains in the Alps: Monte Rosa, the Matterhorn (Cervino) and Mont Blanc (Monte Bianco). The name "Giants" is no exaggeration — the route forms the second half of the legendary Tor des Géants ultra-trail.

Tappa 5 is the stage that drops the route into the Lys valley and the German-speaking Walser heartland of Gressoney. Starting from the high hamlet of Niel (1,550 m), a cluster of stone-roofed Walser houses above Gaby, the 18 km stage climbs through larch woodland and open pasture to a watershed col before descending past alpine farmsteads to Gressoney-Saint-Jean (1,405 m). The Italian Wikipedia article on the Alta via della Valle d'Aosta n. 1 lists the upper variant of this stage beginning at the Rifugio Alfredo Rivetti (2,150 m), which sits directly above Niel — trekkers who overnight at the rifugio simply join the same descent line. Either way, the day belongs to the Lys basin and its long views toward the Monte Rosa glaciers.

This is an E (escursionistico) grade stage on the CAI scale, meaning it follows marked paths with no technical climbing, though the 900 m of ascent and the high-altitude col demand sound fitness and stable weather. Yellow-and-black "Alta Via 1" signposts and the route's distinctive triangular waymarks make navigation straightforward in clear conditions. As a regional walking route within the wider Aosta Valley network, Tappa 5 is most often hiked as one link in a multi-day chain rather than as a standalone outing — but its accessible trailheads make a single-stage day trip entirely feasible.

Route Overview & Stages

The table below places Tappa 5 in the context of the surrounding stages of the Alta Via n. 1, using the stage structure documented for the route. Distances and gains are approximate and vary slightly between the rifugio and valley-floor variants.

Most hikers budget around 6 hours of walking time for Tappa 5, excluding stops. The profile is best described as a long climb to the high point followed by a sustained, knee-testing descent into Gressoney — pace yourself and save energy for the drop.

Highlights & Points of Interest

• Niel (1,550 m) — a beautifully preserved Walser hamlet of stone-and-timber houses in the Vallone di San Grato above Gaby; the traditional starting point of the stage.
• Rifugio Alfredo Rivetti (2,150 m) — the CAI refuge perched above Niel that marks the upper variant of the stage and a classic overnight stop.
• The watershed col — the high point of the day at roughly 2,400 m, the threshold between the Vallone di San Grato and the Lys valley, with the broadest views of the stage.
• Monte Rosa massif — the second-highest mountain in the Alps (4,634 m at the Punta Dufour) dominates the northern skyline once you crest the col.
• Gressoney-Saint-Jean (1,405 m) — the stage end, a Walser resort town with the neo-Gothic Castel Savoia and the Lago Gover lake.
• Castel Savoia — Queen Margherita of Savoy's late-19th-century summer residence, an easy stroll from the village centre and surrounded by an alpine botanical garden.
• Walser cultural landscape — the German-speaking Walser people settled these high valleys from the Middle Ages; their architecture, dialect and farming traditions define the entire stage.
• Lys valley pastures (alpeggi) — working summer farms where the local Toma di Gressoney and Fontina cheeses are still produced; some sell directly to passing hikers.

Best Time to Hike the Alta Via n. 1 della Valle d'Aosta - Tappa 5

The realistic hiking window runs from late June to late September. The high col on Tappa 5 sits around 2,400 m, where snow can linger on north-facing slopes well into early summer. In a normal year the path is reliably clear of snow from the first week of July, and the rifugi along the Alta Via open for the season at the end of June.

The single best month to hike Tappa 5 is September. By then the summer thunderstorm pattern has eased, the air is at its clearest for those Monte Rosa panoramas, the larch woods around Niel begin turning gold, and the August crowds and ferragosto holiday traffic have gone. As of 2026, alpine guidance continues to flag a rising frequency of afternoon convective storms in July and August, so an early start — on the trail by 07:00 and over the col before midday — remains the sensible default in high summer.

July offers the longest daylight and the fullest hut services but the busiest trails and the highest storm risk. Late September is gorgeous but cooler, with the first overnight frosts and shortening days; check rifugio closing dates before relying on them, as most shut in the last week of September. Outside this window the route becomes a serious snow undertaking and is not recommended for general hikers.

Practical Information

Accommodation

Tappa 5 links two well-served valleys, so beds are not hard to find if you book ahead in July and August. The Rifugio Alfredo Rivetti (2,150 m) above Niel is the obvious mountain base, with dormitory half-board (dinner, bed and breakfast) typically running €55–70 per person; a bunk only is around €25–30. In the hamlet of Niel and nearby Gaby there are small guesthouses and agriturismi in the €35–60 range for a room. At the stage end, Gressoney-Saint-Jean offers a full spread of hotels, B&Bs and apartments, with double rooms commonly €70–120 in season and a handful of budget rooms below that. Wild camping is restricted across the Aosta Valley; discreet high-altitude bivouac near a rifugio is tolerated in practice, but pitching in the valley meadows is not. Always confirm half-board with rifugi by phone, as kitchens cater to numbers.

Getting There & Back

The gateway is the lower Lys valley off the A5 Aosta motorway. The nearest railway station is Pont-Saint-Martin, on the Chivasso–Aosta line, about 20 km down-valley; from there local SAVDA / Arriva buses run up the Gressoney valley, serving Gaby (for Niel) and Gressoney-Saint-Jean. Allow roughly 45–60 minutes by bus from Pont-Saint-Martin to Gressoney-Saint-Jean. By car, Pont-Saint-Martin is about 1 hour 15 minutes from Turin and 2 hours from Milan. The closest international airport is Turin (Caselle, TRN), around 1 hour 45 minutes' drive away; Milan Malpensa (MXP) is about 2 hours. Because this is a point-to-point stage, the simplest logistics are to base yourself in the Gressoney valley and use the local bus to shuttle between Gaby and Gressoney-Saint-Jean. Rail schedules can be checked via Trenitalia.

Permits & Fees

No permit is required to walk Tappa 5 of the Alta Via n. 1 — the trail is free and open to all. There are no entry gates or trail fees, as the route lies outside the formal boundaries of the Gran Paradiso National Park. Your only costs are accommodation, food and the local bus (single fares are a few euros). If you plan to overnight in CAI-affiliated rifugi, a Club Alpino Italiano membership card earns a discount on the bed rate but is not mandatory. Full official stage details are published by the regional tourism authority at lovevda.it.

Gear & Packing List

Tappa 5 is a high-mountain day with 900 m of climbing and a real summit col, so pack for fast-changing alpine weather even in July. Essentials are sturdy B-grade hiking boots, trekking poles for the long descent into Gressoney, a windproof and waterproof shell, an insulating mid-layer, sun protection and at least 1.5 litres of water capacity, as reliable sources thin out above the pasture line.

For a single stage you can travel light. A 35–40 litre pack is ample — the Fjällräven Abisko Hike 35 is a comfortable load-hauler for a day with hut overnights. If you are linking several stages of the Alta Via and carrying a sleeping bag liner and extra layers, step up to the Hyperlite Mountain Gear 2400 Windrider or the larger 3400 Windrider for ultralight multi-day comfort.
