Alta Via n. 1 della Valle d'Aosta - Tappa 14

The Alta Via n. 1 della Valle d'Aosta - Tappa 14 is a 14-km point-to-point trail in the Aosta Valley region of north-west Italy, linking Rifugio Létey-Champillon (2,465 m) to Saint-Rhémy-en-Bosses (1,600 m) over a single day. It gains roughly 350 m and loses around 865 m, and is rated intermediate (grade E), with the Col de Champillon as its high point.

About the Alta Via n. 1 della Valle d'Aosta - Tappa 14

The Alta Via n. 1 della Valle d'Aosta — nicknamed the Alta via dei Giganti ("High Route of the Giants") — is one of two great long-distance traverses that cross the Aosta Valley beneath Italy's four-thousand-metre peaks: Monte Rosa, the Cervino (Matterhorn), the Grand Combin and Monte Bianco. The full route runs 14 stages from Donnas (329 m) in the east to Courmayeur (1,223 m) in the west, threading together the Valle del Lys, Val d'Ayas, Valtournenche, the Vallone di Saint-Barthélemy, Valpelline, the Gran San Bernardo valley and Val Ferret along the way.

This page covers Tappa 14 as catalogued in the regional trail database: the stage from Rifugio Létey-Champillon (2,465 m) to Saint-Rhémy-en-Bosses (1,600 m), a 14-km leg that drops out of the high Valpelline into the historic Gran San Bernardo valley. (Be aware that stage numbering varies between sources — the printed Alta Via 1 guidebooks list the final stage to Courmayeur as no. 14, while the official Regione Autonoma Valle d'Aosta catalogue numbers segments differently. The route operator, the Regione Autonoma Valle d'Aosta, maintains the waymarking and the data record this guide follows.)

The hiking is classic Pennine Alps terrain: a morning climb to the wind-scoured Col de Champillon at around 2,709 m, then a long, knee-testing descent past alpine pastures, larch woods and stone hamlets to the valley road that climbs toward the Great St Bernard Pass. It is grand, open country with continuous views, but it demands sure footing on the descent and a respectful eye on the weather — afternoon storms build fast at this altitude.

Route Overview & Stages

The full Alta Via 1 is a committing two-week traverse. The table below places Tappa 14 in context alongside a few representative stages so you can see how this leg fits the wider route. Figures are approximate and drawn from the regional route record.

Tappa 14 itself breaks down simply: a steady 244-metre climb from the refuge to the Col de Champillon, a short, rocky section on the col itself, and then a sustained 9-km descent of roughly 1,100 metres into the Menouve and Gran San Bernardo valleys, finishing on the edge of Saint-Rhémy-en-Bosses. Most fit walkers complete it in 4 to 5 hours of moving time.

Highlights & Points of Interest

• Rifugio Létey-Champillon (2,465 m) — the staffed mountain hut that opens the stage, set in a high cirque beneath the Mont Gelé massif. A natural overnight stop and the only reliable resupply before the col.
• Col de Champillon (2,709 m) — the stage's high point and watershed, a broad grassy saddle with sweeping views back to the Grand Combin and across toward the Gran San Bernardo peaks.
• Lac de Champillon — a small alpine tarn near the refuge, often mirror-still at dawn and a favourite photo stop before the climb begins.
• Vallone di Menouve — the upper valley you descend into below the col, a quiet pastoral basin grazed by Valdostana cattle and dotted with stone alpeggi (summer dairy farms).
• Saint-Rhémy-en-Bosses (1,600 m) — the journey's end, a historic post-house village on the Roman road to the Great St Bernard Pass, famous today for its DOP-protected Jambon de Bosses cured ham.
• Great St Bernard Pass (2,469 m) — just up the valley from the finish, this is one of the oldest Alpine crossings, home to the medieval hospice and the breed of rescue dogs that carry its name.
• Larch and arolla-pine woods — the lower descent passes through some of the Aosta Valley's finest high forest, brilliant gold in late September.
• Roman road remnants — near Saint-Rhémy the trail meets traces of the ancient Via delle Gallie, the imperial route over the pass into what is now Switzerland.

Best Time to Hike the Alta Via n. 1 della Valle d'Aosta - Tappa 14

The reliable hiking window for this stage runs from late June to late September. The Col de Champillon sits at 2,709 m, so snow can linger on north-facing slopes into early July; in heavy-snow years the col may not be cleanly passable until mid-July. Staffed refuges in the Valpelline typically open from around 20 June and close in mid-September, which effectively brackets the comfortable season.

The single best month is September. As of 2026, settled early-autumn weather brings the most stable high pressure of the year, daytime temperatures of roughly 12–18 °C in the valleys, crisp air with excellent long-range visibility toward the Grand Combin and Monte Bianco, and the larch woods on the descent beginning to turn gold. Crowds also thin out after the Italian Ferragosto holiday in mid-August.

July and August are warm and dependable but bring frequent afternoon thunderstorms — start early and aim to be over the col by midday. May and early June are too snowbound at altitude, and from October the refuges close and the first storms arrive. Always check the regional avalanche and weather bulletin before committing, especially in early summer.

Practical Information

Accommodation

The stage is naturally bookended by mountain accommodation. Rifugio Létey-Champillon at the start offers dormitory and small-room beds; a bed in a refuge of this type typically costs around €25–35 per night, with half-board (dinner, bed and breakfast) running roughly €60–75. Booking ahead is essential in July and August, as Aosta Valley huts fill quickly.

At the finish, Saint-Rhémy-en-Bosses and the neighbouring hamlet of Saint-Oyen have small hotels, B&Bs and guesthouses, with double rooms generally €70–110 per night. The historic Châtel-Argent and farm-stay options nearby give a taste of valley life. Wild camping is restricted in the Aosta Valley — pitching for a single night above the treeline near refuges is generally tolerated only with discretion, from dusk to dawn, and never inside protected zones. Plan to use huts and village lodging rather than relying on a tent.

Getting There & Back

The gateway is the regional capital, Aosta, reachable by train from Turin (about 2 hours) and by SAVDA coach from Turin and Milan. The nearest major airport is Turin Caselle (TRN), around 1 hour 45 minutes by road from Aosta; Geneva (GVA) and Milan Malpensa (MXP) are alternatives at roughly 2 to 2.5 hours. From Aosta, SAVDA buses run up the Gran San Bernardo valley to Saint-Rhémy-en-Bosses in about 40–50 minutes, making the finish well connected for the return journey. Reaching the start at Rifugio Létey-Champillon requires walking in from the Valpelline (via Ollomont) or completing the preceding Alta Via stage; there is no road to the refuge.

Permits & Fees

No permit is required to walk Tappa 14 — the Alta Via 1 is a freely accessible waymarked route, signed with the distinctive yellow triangle and "1" markers maintained by the Regione Autonoma Valle d'Aosta. There are no entry fees for the trail itself. Your only costs are refuge beds, meals and transport. If you plan to combine the walk with the nearby Great St Bernard hospice or museum, small admission charges apply there. For current stage data and conditions, consult the official Aosta Valley high-route database (lovevda.it) and the regional tourism portal at Regione Autonoma Valle d'Aosta.

Gear & Packing List

This is a single mountain stage that can be done with a light daypack if you are based at the refuge, or as part of a multi-day traverse with a larger hut-to-hut pack. Either way the priorities are the same: layers for fast-changing alpine weather, solid footwear for the long descent, and trekking poles to spare your knees on the 1,100-metre drop to the valley.

• Footwear: sturdy B0/B1 hiking boots or robust trail shoes with good lugs — the descent has loose, rocky sections.
• Layers: a warm mid-layer and a waterproof shell are non-negotiable at 2,700 m, even in August.
• Pack: for a multi-day Alta Via traverse a 35–55 L pack is ideal. The lightweight Zpacks Arc Haul Ultra 50L and the durable Fjällräven Abisko Hike 35 both suit hut-to-hut hiking, while the Hyperlite Mountain Gear 2400 Windrider is a strong ultralight choice for a fast, single-stage day.
• Essentials: 1.5–2 L water capacity, sun protection (the col is fully exposed), a map or GPX track, and high-energy food.

Frequently Asked Questions

When is the best time to hike Tappa 14?
Late June to late September is the reliable window, governed by snow on the 2,709 m Col de Champillon and refuge opening dates. September is the single best month: stable high pressure, crisp visibility toward the Grand Combin and Monte Bianco, gold larch woods and thinner crowds after mid-August. Avoid May and early June, when the col is still snowbound.

How difficult is the Alta Via 1 Tappa 14?
It is rated grade E — intermediate Alpine hiking on marked paths with no technical climbing. The challenge is endurance and footing: a 244-metre climb to the col followed by a sustained descent of roughly 1,100 metres on rocky ground. Trekking poles, sturdy boots and a head for exposed high passes make it comfortable for fit walkers.

How long is the stage and how many kilometres per day?
Tappa 14 is a single 14-km stage, normally walked in one day of 4 to 5 hours moving time. As part of the full Alta Via 1, daily distances across the 14 stages range from about 10 to 16 km, with each day built around one major pass — so expect significant ascent and descent rather than long flat distances.

What accommodation is available on this stage?
The stage starts at Rifugio Létey-Champillon (beds around €25–35, half-board €60–75) and ends in Saint-Rhémy-en-Bosses, where hotels, B&Bs and guesthouses offer double rooms for roughly €70–110. Book refuges well ahead for July and August. Wild camping is restricted in the Aosta Valley, so plan on huts and village lodging.

Do I need a permit or pay any fees?
No permit is required. The Alta Via 1 is a freely accessible, waymarked route maintained by the Regione Autonoma Valle d'Aosta, with no entry fee for the trail itself. Your only costs are refuge beds, meals and transport. Optional nearby attractions, such as the Great St Bernard hospice museum, charge small separate admission fees.
