Via Alpina Red R128

The Via Alpina Red R128 is a roughly 20 km point-to-point stage in the Hautes-Alpes of France, running from Le Monêtier-les-Bains to Vallouise and gaining about 1,150 m of elevation in a single demanding day. Rated difficult, it crosses the high Col de l'Eychauda on the edge of the Écrins massif, with panoramic glacier and pasture views throughout.

About the Via Alpina Red R128

The Via Alpina is a network of five colour-coded long-distance trails created in 2000 by public and private organisations from the eight Alpine countries, with EU funding running from 2001 to 2008. The project was initiated by the Association Grande Traversée des Alpes in Grenoble, and the Red Trail is the longest of the five routes, comprising 161 numbered stages (R1 to R161) that link Muggia near Trieste, Italy, with the Place du Palais in Monaco. Across those stages the Red Trail crosses all eight Alpine countries: Slovenia, Austria, Germany, Liechtenstein, Switzerland, Italy, France and Monaco.

Stage R128 is one of the French segments, deep in the Hautes-Alpes department close to the Écrins National Park. It connects Le Monêtier-les-Bains, a spa village in the Guisane valley above Briançon, with Vallouise, a historic mountain village at the heart of the Pays des Écrins. The operator listed for the route is via-alpina.org, and the official stage description summarises it simply as "Le Monêtier-les-Bains - Vallouise." This is mountain walking in the truest sense: you climb out of one glacial valley, traverse a high col above 2,400 m, and descend into a completely separate valley system on the far side.

What makes R128 special is its position on the rim of the Écrins, France's second-largest national park and a stronghold of high peaks, glaciers and protected wildlife. The stage sits among summits exceeding 3,000 m, with the Barre des Écrins (4,102 m) dominating the wider skyline. Walkers cross from the busy Serre Chevalier tourism corridor into the quieter, more traditional Vallouise valley, making it a stage of real contrast as well as real altitude.

R128 fits into the wider French section of the Red Trail, which threads down from the Mont Blanc region toward the Maritime Alps and ultimately Monaco. Stages R129 to R134 carry walkers onward through the southern ranges, so R128 is rarely walked entirely in isolation — many hikers tackle it as one link in a multi-week traverse, while day walkers and weekenders treat it as a standout sample of high Écrins terrain. Either way, the stage rewards careful planning: the altitude, the single big col and the limited resupply between the two valleys mean it deserves more respect than its modest 20 km length might suggest.

Route Overview & Stages

R128 is officially a single Via Alpina stage, but it breaks naturally into a climb, a high-col traverse and a long descent. The table below splits the day into practical segments to help you pace it. Distances and elevation figures are approximate and depend on the exact variant and snow conditions.

Total walking distance is around 20 km with roughly 1,150 m of ascent and a steep 1,250 m of cumulative descent into Vallouise (1,166 m), which sits lower than the 1,500 m start point at Le Monêtier-les-Bains. Most fit walkers complete the stage in 6 to 8 hours, not counting breaks. Because almost all the climbing is concentrated in the first half, an early start is the single most useful tactic for the day.

Highlights & Points of Interest

• Le Monêtier-les-Bains (1,500 m) — A spa village in the Serre Chevalier valley with natural hot springs used since Roman times; a comfortable, well-serviced launch point with shops and bakeries to stock up.
• Vallon du Tabuc — A wooded glacial valley climbing south from the Guisane, with cascading streams and stands of larch that glow gold in autumn.
• Col de l'Eychauda (2,425 m) — The high point and pivot of the stage, opening sweeping views toward the Écrins peaks and marking the watershed between the Guisane and Vallouise valleys.
• Glacier de Séguret Foran — Hanging glacier and cirque visible on the descent, a reminder of the icy heart of the Écrins massif just to the west.
• Chambran — A small summer hamlet and trailhead in the Onde valley with a refuge, the first reliable resupply and rest point after the col.
• Vallée de l'Onde — A quiet, pastoral valley inside the Écrins National Park, known for chamois, ibex and golden eagles.
• Vallouise (1,166 m) — A historic village with the 15th-century church of Saint-Étienne and a Vaudois (Waldensian) heritage that gives the wider valley its name.
• Barre des Écrins (4,102 m) — The highest peak of the southern French Alps, dominating the skyline and the only 4,000 m summit entirely within France.

Best Time to Hike the Via Alpina Red R128

The viable window for R128 is short because the route crosses a col above 2,400 m. From late June, snow usually clears from the Col de l'Eychauda, though north-facing slopes and gullies can hold patches into early July. July and August offer the most reliable footing, the longest daylight and staffed refuges, but they also bring afternoon thunderstorms that build quickly over the Écrins peaks — start before 7 a.m. to be off the col by midday.

The single best month is September. As of 2026, early September delivers stable high-pressure weather, dramatically thinner crowds than the July–August peak, cooler walking temperatures and the first golden tints in the larch forests, while most refuges still operate until around mid-month. By late September, refuges begin closing and the first autumn snow can dust the col, so aim for the first three weeks. Avoid May and early June (lingering snowfields, high avalanche residue and meltwater-swollen streams) and October onward, when the col may be impassable without winter equipment.

Practical Information

Accommodation

You can sleep in valley accommodation at both ends and treat R128 as a long day, or break the journey with a mountain refuge. In Le Monêtier-les-Bains, hotels and guesthouses run roughly €70–€130 per double room, with a few budget rooms and gîtes from about €25–€40 per person. Mountain refuges along or near the route — including refuges in the Chambran and Onde area — typically charge €20–€28 for a dormitory bed, with half-board (dinner, bed and breakfast) around €50–€60 per person; booking ahead is essential in July and August.

Wild camping is restricted inside the Écrins National Park: bivouacking is tolerated only between 7 p.m. and 9 a.m., more than one hour's walk from the park boundary or a road, and you must pitch and strike each day. Organised campsites in Vallouise and the Pays des Écrins charge roughly €15–€25 per pitch. Plan your weight and resupply carefully using a hike planner — you can map each day, attach accommodation notes and track food on how many calories you need hiking a full day.

Getting There & Back

The nearest railway station is Briançon, about 15 km from Le Monêtier-les-Bains and reached by direct overnight train from Paris (Gare d'Austerlitz, around 11–12 hours) or by TGV to Oulx in Italy followed by a connecting bus. From Briançon, regional buses run up the Serre Chevalier valley to Le Monêtier-les-Bains in roughly 25–35 minutes. The nearest major airports are Turin (about 2 hours by road via the Montgenèvre pass) and Grenoble or Marseille (around 2.5–3.5 hours). At the finish, Vallouise is connected to Briançon and the rail network by L'Argentière-les-Écrins, served by valley buses; check the Hautes-Alpes regional transport timetables before you travel, as mountain services thin out in shoulder season.

Permits & Fees

No permit or fee is required to walk R128, even where it passes through the Écrins National Park. Access is free and open to all. You must, however, follow park regulations: dogs are banned (even on a lead), drones and fires are prohibited, picking plants and disturbing wildlife is forbidden, and the bivouac rules above apply. Refuge and campsite charges are the only mandatory costs. For authoritative, up-to-date rules consult the Écrins National Park and the official stage page from the Via Alpina trail authority.

Gear & Packing List

R128 is a high-alpine day stage, so pack for fast weather changes even in midsummer: a waterproof shell, an insulating mid-layer, sun protection and 2 litres of water minimum, since reliable sources thin out above the treeline. Trekking poles take strain off knees on the 1,250 m descent into Vallouise, and sturdy boots with ankle support handle the rocky, occasionally snow-streaked col. If you are linking several Via Alpina stages, weight discipline matters: a frameless or lightweight pack in the 35–55 litre range covers refuge-to-refuge travel comfortably.

Good pack choices include the 2400 Windrider for a minimalist day or hut load, the larger 3400 Windrider if you carry camping kit under the park's bivouac rules, and the supportive Abisko Hike 35 for those who prefer a framed daypack.

Frequently Asked Questions

When is the best time to hike the Via Alpina Red R128?
The realistic season runs from late June to late September. July and August are warmest and have staffed refuges but bring afternoon thunderstorms. The single best month is September, especially the first three weeks, when high-pressure weather is most stable, crowds thin out, temperatures are cool and the col is usually snow-free before autumn arrives.

How difficult is the R128 stage?
It is rated difficult. The route climbs about 1,150 m to cross the Col de l'Eychauda at 2,425 m and then descends roughly 1,250 m into Vallouise over about 20 km. The terrain is rocky and exposed at altitude, and snow can linger on the col into early July. Good fitness, mountain experience and proper footwear are needed.

How long is each day on R128?
R128 is a single Via Alpina stage covering around 20 km. Most fit hikers complete it in 6 to 8 hours of walking, not counting breaks. Because almost all the ascent is packed into the first half of the day before the col, an early start of 6–7 a.m. is strongly recommended to clear the high point before afternoon storms build.

Where can I stay along the route?
You can use valley accommodation in Le Monêtier-les-Bains (hotels €70–€130, gîtes from €25) and Vallouise, or break the day at a mountain refuge near Chambran or in the Onde valley, where dorm beds cost €20–€28 and half-board runs €50–€60. Campsites in the valleys charge €15–€25 per pitch; book refuges ahead in summer.

Do I need a permit or pay a fee?
No permit or entry fee is required to walk R128, even through the Écrins National Park, and access is free. However, park rules apply: no dogs, no fires, no drones, and bivouacking is only allowed between 7 p.m. and 9 a.m. far from roads. Your only mandatory costs are refuge, campsite and transport fares.
