Via Alpina Red R142

The Via Alpina Red R142 is a roughly 8 km point-to-point alpine stage in Italy's Maritime Alps, linking Rifugio Questa to Rifugio Morelli-Buzzi with about 550 m of ascent over a single demanding day. Rated challenging, it crosses the high Colle del Chiapous beneath the Argentera, the range's tallest peak.

About the Via Alpina Red R142

The Via Alpina is a network of five long-distance hiking trails threaded across the entire Alpine arc, established in 2000 by partner organisations from eight countries: Slovenia, Austria, Germany, Liechtenstein, Switzerland, Italy, France and Monaco. The initiative grew with EU funding between 2001 and 2008 and was designed to support sustainable development in remote mountain communities while giving walkers a continuous, waymarked thread through the highest landscapes in Europe.

The Red Trail is the longest of the five routes, running 161 stages (R1 to R161) from Muggia near Trieste all the way to the Palais de Monaco on the Mediterranean. Stage R142 sits deep in the final Italian section, in the Maritime Alps of Piedmont, where the great peaks crowd together before the chain drops south toward the French Mercantour and the sea. The official Via Alpina description for this leg is simply Rifugio Questa – Rifugio Morelli-Buzzi, a hut-to-hut crossing entirely above the treeline.

This is a short stage by distance — around 8 km — but it earns its challenging grade through altitude, rough granite terrain and the crossing of the Colle del Chiapous at roughly 2,526 m. Walkers move through the Parco naturale delle Alpi Marittime, the largest protected area in Piedmont, beneath the Argentera (3,297 m), the highest summit of the Maritime Alps. Both refuges sit above 2,300 m, so although the daily mileage is modest, the day is committing, exposed to weather, and best treated as a serious mountain outing rather than a casual walk.

Most hikers tackle R142 as one link in a multi-day traverse of the Maritime Alps, chaining it with the surrounding R141 and R143 stages around Rifugio Questa and the Argentera massif. Reliable navigation matters here: the path is marked with Via Alpina signage and the local CAI red-and-white blazes, but the granite slabs and boulder fields can obscure the line in poor visibility.

The Maritime Alps occupy a special place in the wider chain. This is the last great rampart of the Alps before they sink toward the Mediterranean, and because the sea lies barely 50 km to the south the range carries an unusually rich mix of alpine and Mediterranean plant life. Endemic species such as the saxifrage Saxifraga florulenta, found nowhere else on Earth, cling to the granite walls around the Argentera. For the Via Alpina walker, R142 is therefore not just another high pass but a passage through one of the most biologically distinctive corners of the entire route, where ibex reintroduced over decades now number in the thousands across the Italian and adjoining French Mercantour parks.

Route Overview & Stages

R142 is a single stage, but it is rarely walked in isolation. The table below places it in context with the neighbouring Maritime Alps legs of the Red Trail so you can plan a coherent two-to-three day block. Figures are approximate and drawn from the official Via Alpina stage data and park topography.

The R142 stage itself climbs from Rifugio Questa (about 2,388 m) over rocky benches toward the Colle del Chiapous, then descends past the great Chiotas reservoir system to Rifugio Morelli-Buzzi (about 2,351 m), which sits directly beneath the north face of the Argentera. Expect five to six hours of moving time given the terrain. There is no intermediate water point you can fully rely on once the early-season snowmelt fades, so fill up at the huts and carry enough for the climb. The path gains height steadily rather than steeply, but the final pull to the Colle del Chiapous is rocky and can hold a snow patch into July, where a slip would be consequential; trekking poles and a steady pace pay off here more than raw speed.

Highlights & Points of Interest

• Rifugio Questa (2,388 m) — a classic CAI stone refuge on the shore of Lago delle Portette, a fine launch point ringed by granite spires.
• Colle del Chiapous (2,526 m) — the high pass of the stage, opening sudden views toward the Argentera massif and the Chiotas basin.
• Argentera (3,297 m) — the highest peak of the Maritime Alps, dominating the skyline above Rifugio Morelli-Buzzi.
• Lago del Chiotas & the Chiotas dam — one of Europe's largest pumped-storage hydroelectric reservoirs, an arresting man-made contrast in a wild basin.
• Rifugio Morelli-Buzzi (2,351 m) — the stage end, a welcoming hut and the standard base for ascents of the Argentera.
• Parco naturale delle Alpi Marittime — protected since the 1980s and home to one of the largest ibex and chamois populations in the western Alps.
• Valletta and Gesso valleys — glacially carved hanging basins strewn with tarns, a signature feature of this corner of Piedmont.

Best Time to Hike the Via Alpina Red R142

The walking season in the high Maritime Alps is short. Snow lingers on north-facing slopes and around the Colle del Chiapous well into June, and the staffed refuges typically open only from mid-June and close in mid-to-late September. For 2026, plan your crossing within the window of late June through the third week of September, and confirm hut opening dates directly before committing.

Early July can still hold old snow on the pass, which makes the granite slabs slippery and the route-finding harder. August brings the warmest, most stable weather but also the heaviest afternoon thunderstorms and the busiest huts — book ahead. The single best month is September: by then the snow is long gone, the air is clear and stable, crowds thin out, and the larch-fringed lower valleys begin to turn gold. As of 2026, afternoon convective storms remain the main hazard all summer, so start early and aim to clear the Colle del Chiapous well before midday.

Practical Information

Accommodation

This stage is built around two mountain refuges, and there is no village in between, so a hut booking is effectively mandatory. Rifugio Questa and Rifugio Morelli-Buzzi are both CAI-affiliated huts offering dormitory bunks and cooked half-board. Budget roughly €60–75 per person for a dorm bed with dinner and breakfast in 2026, with CAI and reciprocal alpine-club members receiving a meaningful discount on the bunk. Bring cash, as card payment is unreliable at altitude. Wild camping is restricted inside the Parco naturale delle Alpi Marittime; bivouacking is tolerated only above the huts, after sunset and before sunrise, with no tents pitched in the daytime — always check current park rules. Carry a sleeping-bag liner, as huts provide blankets rather than fresh linen.

Getting There & Back

The gateway town is Cuneo in Piedmont, served by frequent regional trains from Turin (about 1 hour 30 minutes). From Cuneo, seasonal buses and shared taxis run up the Valle Gesso to Terme di Valdieri and the Gias delle Mosche / San Giacomo trailheads, from where the approach paths to Rifugio Questa begin. Allow most of a day for the transfer and the initial climb. The nearest major airports are Turin (Caselle), roughly 2 hours 30 minutes away by car or rail-plus-bus, and Nice Côte d'Azur on the French side, useful if you are walking the Red Trail toward Monaco. Driving up the Gesso valley and parking at the road head is the simplest option if you have a car.

Permits & Fees

No permit is required to walk R142, and access to the Parco naturale delle Alpi Marittime is free. There are no trail tolls. Your only fixed costs are refuge half-board, transport up the valley, and any optional parking. Drones, fires and off-trail camping are regulated inside the park, so review the official park regulations before you go.

Gear & Packing List

R142 is short but high and exposed, so pack for genuine alpine conditions even in midsummer. A 35–55 litre pack comfortably holds hut kit, layers and a day's food and water; the lightweight Arc Blast 55L or the more structured Atmos AG 50 both suit a multi-day hut traverse, while the Abisko Hike 35 is ideal if you are travelling fast and light between staffed refuges. Essentials include sturdy B-rated hiking boots with grip for wet granite, trekking poles for the pass, a warm midlayer and waterproof shell, sun protection for the high basins, at least 1.5 litres of water capacity, and a headtorch and sleeping-bag liner for the huts. A paper map and the ability to navigate in cloud are non-negotiable given the boulder terrain.

Because the daily distances are short, many hikers under-eat on hut traverses and feel it on the climbs. It is worth reading How Many Calories Do You Need Hiking a Full Day? before you finalise your food plan, and if you are weighing pack options, Best Ultralight Backpacks of 2026 compares several of the packs above head to head.

Similar Trails You Might Like

If the high granite and hut-to-hut rhythm of R142 appeals, Italy's classic Dolomite high routes deliver the same alpine commitment over longer multi-day itineraries. These Alte Vie thread refuge to refuge through some of the most dramatic limestone scenery in the Alps, and pair naturally with a Maritime Alps trip for a full Italian high-mountain season. Walkers chasing rugged border-country trails further afield often enjoy the Theth to Valbona crossing in the Albanian Alps as a contrast.

Frequently Asked Questions

When is the best time to hike the Via Alpina Red R142?
Late June to mid-September is the viable window, once snow has cleared the Colle del Chiapous and the refuges are staffed. September is the single best month: stable clear weather, no lingering snow, thinner crowds and golden larches lower down. Avoid early July if snow remains, and start early in August to beat afternoon thunderstorms on the high pass.

How difficult is the Via Alpina Red R142?
It is rated challenging. Though only about 8 km long, the stage stays above 2,300 m, crosses the rocky Colle del Chiapous at roughly 2,526 m, and travels over granite slabs and boulder fields that demand sure footing and confident navigation. Altitude, exposure to weather and the absence of any bail-out village make it a serious mountain day rather than a casual walk.

How long does each day on the route take?
R142 is a single stage of roughly 8 km with about 550 m of ascent, taking five to six hours of moving time given the rough terrain and the pass crossing. Most walkers chain it with the neighbouring R141 and R143 stages, each a comparable half-to-full mountain day, building a two-or-three day traverse of the Maritime Alps between staffed refuges.

What accommodation is available on the Via Alpina Red R142?
The stage runs between two CAI mountain refuges, Rifugio Questa and Rifugio Morelli-Buzzi, both offering dormitory bunks and cooked half-board for roughly €60–75 per person in 2026. There are no villages or hotels en route, so booking ahead is essential. Bring cash and a sleeping-bag liner; wild camping is restricted within the national park and tents may not be pitched during the day.

Do I need a permit or pay fees for the Via Alpina Red R142?
No permit is needed and entry to the Parco naturale delle Alpi Marittime is free, with no trail tolls. Your only fixed costs are refuge half-board, transport up the Valle Gesso from Cuneo, and optional parking at the road head. Fires, drones and off-trail camping are regulated inside the park, so check the official park rules before setting out.
