Via Alpina Red R104

The Via Alpina Red R104 is a roughly 13 km point-to-point mountain stage in Switzerland, running from Gsteig bei Gstaad in the Bernese Oberland over the Col du Sanetsch to Godey in Valais, gaining about 1,150 m of elevation in a single day. Rated demanding (Swiss T3), it crosses a wild high pass linking two language regions and two distinct alpine worlds.

About the Via Alpina Red R104

The Via Alpina is the most ambitious trail network in the Alps: five colour-coded routes weaving through all eight Alpine countries. The flagship Red Trail alone covers 161 stages and around 2,500 km, stretching from Trieste on the Adriatic to the Principality of Monaco on the Mediterranean. It was created in 2000 by partner organisations from the eight Alpine nations with European Union funding, and since January 2014 it has been administered by CIPRA, the International Commission for the Protection of the Alps, based in Liechtenstein.

Stage R104 is one of the Swiss links in that chain. It carries walkers from Gsteig bei Gstaad (about 1,184 m), a quiet village at the southern tip of the Saanenland, southwards over the Col du Sanetsch / Sanetschpass (roughly 2,251 m) and down to Godey, the hamlet beside the Sanetsch reservoir on the Valais side. In a single walking day the route climbs out of a German-speaking Bernese valley and tips over a historic trading pass into French-speaking Valais — a crossing that has linked Gstaad and Sion for centuries.

What makes R104 memorable is its contrast. The northern approach is green and pastoral, threading past chalets, grazing cattle and waterfalls. Above the treeline the landscape turns austere: limestone slabs, scree, and the broad saddle of the Sanetsch with the Wildhorn massif rising to the east. Then the trail drops to the artificial Lac de Sénin (Lac du Sanetsch), an emerald reservoir that feels almost out of place after the raw mountain terrain. For long-distance walkers it is a logical, scenic bridge between the Berner Oberland highlands and the deep valleys of Valais.

Route Overview & Stages

R104 is normally walked in one direction, south from Gsteig to Godey, so that the bigger climb comes early and the descent is shorter. The figures below are typical planning estimates; on the ground, snow, route choice and the optional cable car at Godey all affect timings.

Most fit walkers complete the stage in 5 to 6 hours of moving time. Allow extra for photos at the pass, lunch at the Sanetsch refuge, and the steep, sometimes rough descent toward the reservoir.

Highlights & Points of Interest

• Gsteig bei Gstaad (1,184 m) — A photogenic Bernese Oberland village with a 15th-century wooden church and traditional chalets; the trailhead and last reliable shop before the climb.
• Col du Sanetsch / Sanetschpass (~2,251 m) — The crossing's high point and watershed between the Saane and Rhône drainages, used as a trade route between Gstaad and Sion since the Middle Ages.
• Wildhorn massif (3,247 m) — The dominant peak east of the pass, often holding snow and small glaciers well into summer.
• Lac de Sénin / Lac du Sanetsch — A reservoir formed by the Sanetsch dam, its turquoise water set against bare limestone, marking the Valais side of the route.
• Godey hamlet — The Valais terminus of the stage, with a mountain restaurant and the top station of the Sanetsch cable car down to the Rhône valley.
• Sanetsch waterfalls — Cascades on the southern descent where meltwater pours off the karst plateau toward Conthey.
• Tsanfleuron plateau and glacier — Visible to the west, a vast slab of folded limestone and shrinking ice above the Diablerets.
• Language frontier — Somewhere near the pass you cross the Röstigraben, the cultural border between German-speaking Bern and French-speaking Valais.

Best Time to Hike the Via Alpina Red R104

This is a true high-alpine stage, and the pass holds snow far longer than the valleys suggest. The realistic season runs from late June to early October. In a normal year the Col du Sanetsch is snow-free for walking by the second half of June, but after a heavy winter, drifts can linger on the northern approach into early July.

The single best month is September. By then the snow is gone, the alpine meadows have firmed up after the summer storms, the air is clearest for Wildhorn and Tsanfleuron views, and crowds thin out once the school holidays end. Daytime temperatures at the pass typically sit around 8–14 °C in September, cooling sharply once cloud rolls in.

July and August offer the warmest, longest days and the most reliable cable-car and refuge service, but also the highest chance of afternoon thunderstorms — start early and aim to be over the pass before midday. As of 2026, alpine forecasters continue to report earlier snowmelt and more volatile summer weather across the western Swiss Alps, so check a mountain-specific forecast the night before and again at breakfast. Outside roughly mid-June to mid-October, treat R104 as a snow route requiring winter mountaineering skills, not a hiking stage.

Practical Information

Accommodation

You can sleep at either end or near the pass. In Gsteig, guesthouses and B&Bs typically run €90–€140 for a double room with breakfast; nearby Gstaad has the full range up to luxury. Near the top, the refuge/auberge at the Sanetsch (Godey) offers dormitory beds and simple rooms; expect roughly €60–€80 per person in a dortoir with half board, in line with Swiss mountain-inn pricing. Wild camping is restricted in Switzerland; a discreet single-night bivouac above the treeline is tolerated in practice but not permitted near the reservoir, in protected zones, or on private pasture — ask at huts first. Book ahead for July, August and weekends, as bed space at the pass is limited.

Getting There & Back

Gsteig is reached by Swiss public transport via Gstaad. From Geneva Airport, take the train to Montreux or Spiez, then the scenic MOB/regional line to Gstaad, and the PostBus to Gsteig — around 3 to 3.5 hours total. From Zürich Airport, allow about 3.5 to 4 hours via Spiez and the Lenk/Gstaad lines. At the far end, the Sanetsch cable car descends from Godey toward the Sion area, where trains on the Rhône valley main line connect onward; the cable car runs seasonally, so verify operating dates before relying on it. Plan rail and bus connections with the national timetable at SBB.

Permits & Fees

No permit or entry fee is required to walk R104 — Switzerland's marked footpath network is free and open to all. Your only fixed costs are accommodation, meals, and optional transport such as the Sanetsch cable car (a one-way mountain cable-car fare in this region is typically €15–€25). For full route, stage and refuge details, consult the official network at Via Alpina.

Gear & Packing List

R104 packs real alpine exposure into one day, so pack for fast weather changes even in midsummer: waterproof shell, insulating layer, hat and gloves, sun protection, 1.5–2 litres of water, and boots with grip for wet limestone and possible old snow on the pass. Trekking poles ease the steep Valais descent. Because most of the kilometre count is uphill, a light pack pays off — a 35–50 litre load carried well makes the climb far more pleasant. Good options from our database include the 2400 Windrider for ultralight day-stage carries, the larger 3400 Windrider for multi-day Via Alpina sections, and the supportive Abisko Hike 35 if you prefer a framed pack for the steep ground.

Frequently Asked Questions

When is the best time to hike the Via Alpina Red R104?
September is the best single month: the Col du Sanetsch is reliably snow-free, the views toward the Wildhorn and Tsanfleuron are at their clearest, and crowds thin after the summer holidays. The broader season runs late June to early October. Avoid the shoulder weeks after heavy winters, when snow can linger on the northern approach to the pass.

How difficult is the R104 stage?
It is a demanding mountain hike, graded T3 on the Swiss hiking scale. You gain about 1,150 m to a 2,251 m pass, then descend steep, sometimes rough terrain with loose limestone and possible old snowfields. Sure-footedness and a head for moderate exposure are needed, but no technical climbing or special equipment beyond good boots and poles.

How long is the stage and how much do you walk per day?
R104 is a single Via Alpina stage of roughly 13 km, designed to be completed in one walking day of about 5 to 6 hours of moving time. Most of that distance is the climb from Gsteig to the Col du Sanetsch, followed by a shorter, steeper descent to Godey beside the Sanetsch reservoir.

Where can you stay along the route?
You can base in Gsteig, with guesthouses around €90–€140 per double, or sleep high at the Sanetsch refuge near Godey, where a dormitory bed with half board runs roughly €60–€80 per person. Gstaad nearby adds plenty of hotels. Book ahead for July, August and weekends, since high-altitude bed space is limited.

Do you need a permit or pay a fee?
No. Switzerland's signposted hiking network is free and open, so R104 requires no permit or entry fee. Your costs are accommodation, food, and optional transport such as the seasonal Sanetsch cable car from Godey, which typically costs €15–€25 one way. Always confirm cable-car operating dates before you rely on it to descend.
