Via Alpina Red R135

The Via Alpina Red R135 is a roughly 13 km point-to-point trail stage in the Cottian Alps of Piedmont, Italy, running from Chiappera to Chialvetta and gaining around 900 m of elevation in a single day. Rated moderate, it threads the high Maira Valley beneath the dramatic Rocca Provenzale spire and through some of the most unspoiled pastoral country in the western Alps.

About the Via Alpina Red R135

The Via Alpina Red R135 is stage 135 of the Red Trail, the longest of the five colour-coded routes that make up the Via Alpina network. The Red Trail alone runs 161 documented stages from Trieste in northeastern Italy to Monaco on the Mediterranean, crossing all eight Alpine nations — Slovenia, Austria, Germany, Liechtenstein, Switzerland, Italy, France and Monaco. The wider Via Alpina was created in 2000 by a coalition of public and private organisations from those eight countries, and received European Union funding from 2001 until 2008. Coordination passed to CIPRA in Liechtenstein in 2014.

R135 sits deep in the southwestern arc of the route, within the Valle Maira (Maira Valley) in the province of Cuneo, Piedmont. The stage connects the hamlet of Chiappera, at the valley head near Acceglio, with the smaller settlement of Chialvetta a little further down-valley. The official Via Alpina page lists this segment as stage 315 in its database, operated by via-alpina.org. The OSM record describes it simply as "Chiappera - Chialvetta."

This is borgate country — clusters of dry-stone hamlets where Occitan culture and language survive, and where the Via Alpina's stated mission of "sustainable development in remote mountain areas" is visible in the locally run mountain refuges that keep these valleys alive. Walkers on R135 trade big-name summits for intimacy: larch woods, terraced meadows, grazing herds and the constant presence of jagged limestone towers overhead.

The Maira Valley earned a reputation in the 1990s and 2000s as a model of "slow tourism" — a deliberate counterpoint to the lift-served ski resorts of the northern Alps. After decades of depopulation that emptied dozens of hamlets, a generation of returnees restored stone houses into refuges and posto tappa, reopened mule tracks, and waymarked the long-distance Percorsi Occitani circuit that R135 partly shares. For the hiker this means a stage that feels lived-in rather than wild: you pass working dairies, hand-mown hay meadows and chapels frescoed centuries ago, all within sight of 2,400 m rock walls. It is one of the most rewarding short stages anywhere on the Via Alpina Red Trail for travellers who want culture alongside their climbing.

Route Overview & Stages

R135 is a single Via Alpina stage, but most hikers walk it as part of a multi-day traverse of the Maira and Stura valleys. The table below breaks the stage into its natural segments and places it among its neighbouring Red Trail stages. Distances are approximate, as the official record does not publish a fixed length for every segment.

Plan to walk R135 in 4 to 6 hours of moving time. If you are stitching together a longer route, day-by-day planning, GPX import and accommodation notes can all be tracked using HikeLoad's hike planner.

Highlights & Points of Interest

• Rocca Provenzale (2,402 m) — the unmistakable vertical limestone tower that looms over Chiappera, one of the most photographed rock spires in the western Alps and a magnet for climbers.
• Chiappera (1,614 m) — the highest permanent hamlet in the Maira Valley, with a small church, refuge and campsite at the valley head beneath the Monte Castello group.
• Lago di Saretto — a turquoise reservoir below the village of Saretto, framed by larch forest and a popular rest stop early in the stage.
• Occitan borgate — the dry-stone hamlets scattered across the valley, where the Occitan language and Provençal mountain culture are still actively preserved.
• Chialvetta (1,494 m) — a tidy stone village in the Vallone di Unerzio, home to one of the valley's best-known refuges and a hub for surrounding trails.
• Ecomuseo dell'Alta Valle Maira — a network of small museums at Chialvetta documenting rural alpine life, farming tools and the valley's depopulation history.
• Monte Castello (2,452 m) — the rampart of peaks that closes the head of the Maira Valley and feeds the views for the first hours of the walk.
• Alpine pastures of Unerzio — flower meadows grazed by cattle and sheep through summer, the source of the valley's prized Castelmagno-style cheeses.

Best Time to Hike the Via Alpina Red R135

The hiking window for R135 runs from mid-June to early October, when the high pastures are clear of snow and the valley refuges are staffed. September is the single best month: as of 2026 it offers the most stable high-pressure weather of the season, daytime temperatures around 14–20°C, dry trails, thinner crowds than August, and the first golden colour in the larch woods. Wildflowers peak earlier, in late June and July, but those months also bring afternoon thunderstorms that build quickly over the Cottian ridgelines.

July and August are warm and reliable for daylight but busy at refuges and prone to heat haze; book beds well ahead. By mid-October overnight frosts return, refuges begin closing, and the first snowfalls can dust the passes above 2,000 m. Outside the June–October window the route should be treated as a winter mountaineering objective, not a hiking stage. Whatever month you choose, check the local forecast the evening before and start early to be off the high ground before afternoon storm cells form.

One local quirk worth planning around: the Maira Valley faces broadly south and east, so it warms and dries faster after rain than shaded northern valleys, but it also bakes in midday August sun on the open pastures above Saretto. Carry extra water on hot days, since reliable springs thin out once you leave the tree line. In a typical 2026 season the most settled walking weather clusters around the first three weeks of September, when the meadows have turned to seed and the larch needles begin to glow gold against the grey rock.

Practical Information

Accommodation

R135 is a refuge-and-village stage, so you can sleep indoors at both ends and in between. Expect roughly the following 2026 rates:

• Mountain refuges (rifugi): €25–€35 per person for a dormitory bed; half-board (bed, dinner, breakfast) typically €55–€70.
• Posto tappa / guesthouses in the borgate: €30–€50 per person, often family-run with home-cooked Occitan meals.
• Camping: a small campsite operates at Chiappera (around €10–€15 per pitch); wild camping is discouraged and informally tolerated only above the tree line for a single night, low-impact.

Chialvetta's long-running refuge and the Chiappera campground are the anchor points; reserve by phone or email a few days ahead in peak summer. Many places are cash-friendly but card coverage is patchy in the upper valley, so carry euros.

Getting There & Back

The Maira Valley has no railway, so access is by car or seasonal bus from Cuneo, the nearest mainline rail town. Cuneo is about 90 minutes by train from Turin, and from Cuneo a valley bus runs up to Acceglio and Chiappera in roughly 90 minutes during summer. The nearest major airport is Turin–Caselle (TRN), around 2.5 hours by road from Chiappera; Cuneo–Levaldigi (CUF) is closer but has fewer connections. Chialvetta, in the side Vallone di Unerzio, is reached by a short link road from the main valley; coordinate the return bus timetable carefully, as services are sparse and seasonal. Driving and parking at Chiappera is the most flexible option for a single-stage walk.

Permits & Fees

No permit is required to hike the Via Alpina Red R135. The trail crosses open mountain land and grazing pastures that are freely accessible on foot. There are no entry gates or daily quotas. Your only costs are accommodation, meals and transport. If you camp, do so responsibly and pack out all waste; the valley's economy depends on the meadows staying clean and the herds undisturbed.

For route updates, GPX downloads and the full stage description, consult the coordinating body's official portal at CIPRA International, which has managed the Via Alpina network since 2014. Always cross-check refuge opening dates and bus timetables before you travel, as both change yearly and the upper Maira Valley sees only seasonal public transport.

Gear & Packing List

R135 is a moderate single-day alpine stage, but mountain weather can swing 15°C between a sunny pasture and a storm-darkened pass, so pack for cold and wet even in July. A 35–55 litre pack is ample for a multi-day refuge traverse where you do not carry a tent. The lightweight, frameless 2400 Windrider suits fast-and-light refuge hopping, while the larger 3400 Windrider gives room for a tent and food if you plan to camp at Chiappera. Hikers who prefer a structured, hard-wearing pack for variable alpine terrain often choose the Abisko Hike 35.

Bring a waterproof shell, an insulating mid-layer, sturdy trail or light hiking boots, trekking poles for the descent into Chialvetta, 1.5–2 litres of water capacity, and sun protection for the exposed pastures.

Frequently Asked Questions

When is the best time to hike the Via Alpina Red R135?
The season runs mid-June to early October, but September is the best single month. As of 2026 it brings the most stable weather, comfortable 14–20°C days, dry trails, fewer crowds than August and the first golden larch colour. July and August are reliably warm but busier and more prone to afternoon thunderstorms over the Cottian ridges.

How difficult is the R135 stage?
R135 is rated moderate. Over roughly 13 km it gains about 900 m and descends to Chialvetta on well-marked mountain paths and farm tracks. There is no technical scrambling, but the sustained climbs, alpine altitude and exposed pastures demand reasonable fitness, sure footing and proper footwear. Most fit hikers complete it in 4 to 6 hours of moving time.

How many kilometres per day does the route involve?
R135 itself is a single day of about 13 km with roughly 900 m of ascent. If you join it to neighbouring Red Trail stages, expect daily distances of 13–16 km and 900–1,100 m of climbing — typical Via Alpina figures. Daily mileage on this route is governed more by elevation gain and refuge spacing than by raw distance.

What accommodation is available along the way?
You can sleep indoors at both ends. Mountain refuge dorm beds run €25–€35, with half-board around €55–€70 in 2026. Family-run guesthouses in the Occitan borgate cost €30–€50 per person, and a small campsite at Chiappera charges roughly €10–€15 per pitch. Card payment is patchy in the upper valley, so carry euros and book ahead in peak summer.

Do I need a permit to hike R135?
No. The Via Alpina Red R135 crosses open mountain land and grazing pastures that are freely accessible on foot, with no permits, entry gates or daily quotas. Your only costs are accommodation, meals and transport. If you wild camp above the tree line, keep it to a single low-impact night and pack out everything you bring in.
