Via Alpina Yellow B20

The Via Alpina Yellow B20 is a point-to-point alpine stage in the UNESCO-listed Italian Dolomites, running from Rifugio Città di Fiume across the Giau Pass (Passo di Giau, 2,236 m) to the mountain village of Pieve di Livinallongo. Trending mostly downhill overall, the stage combines a 7,000-year-old Mesolithic archaeological site, a panoramic pass crossing above the treeline, and sweeping views of Marmolada (3,343 m) — the highest peak in the Dolomites — on the long western descent.

About the Via Alpina Yellow B20

The Via Alpina is Europe's most ambitious long-distance alpine network: five colour-coded routes linking Slovenia and the Adriatic coast to Monaco on the Mediterranean, threading through eight countries across more than 340 stages. The Yellow Route — coded "B" for its Italian alignment — departs Trieste and pushes westward through the northeastern Italian Alps and Dolomites across 44 stages of committed mountain walking through some of the continent's most storied terrain.

Stage B20 sits squarely in the heart of the Dolomites UNESCO World Heritage Site, a designation awarded in 2009 to nine distinct Dolomite systems for their exceptional natural beauty and outstanding geological value. This is mountain scenery on a grand scale: sheer limestone towers, glaciated summits, and flower-strewn alpine meadows that have drawn painters, geologists, and walkers for more than two centuries.

What distinguishes B20 from neighbouring stages is the layering of cultural and natural depth on a single route. The Mondeval plateau above Rifugio Città di Fiume yielded one of Europe's most important prehistoric discoveries in 1987: the skeleton of a hunter-gatherer male, aged approximately 35–45 at death, buried with hunting tools and ornaments dating to roughly 7,000 BCE. Known as the Mondeval Man, he is now exhibited at the Museum of Cadore in Pieve di Cadore. Walking across the plateau where he lived and was buried gives this stage a resonance that purely scenic routes cannot match.

The stage also traverses the approaches to Livinallongo del Col di Lana, a Ladin-speaking valley that formed part of the front line between Austria-Hungary and Italy during World War One. The Col di Lana ridge, visible from the valley floor as the route descends, was the site of some of the most intense fighting in the Dolomite campaign — including a famous underground explosion in April 1916 that demolished the Austrian-held summit. Interpretation panels and memorial sites in and around Pieve di Livinallongo document this history, giving the stage's end point considerable weight alongside the natural drama of the route.

Route Overview & Stages

The stage runs southwest from Rifugio Città di Fiume, crosses the open Mondeval plateau, climbs to the Giau Pass (Passo di Giau, 2,236 m), then descends the long western flank of the pass to Pieve di Livinallongo in the Cordevole valley. According to the official Via Alpina route description, B20 is "mostly downhill" overall, with the Marmolada massif providing a dominant landmark on the western horizon throughout the descent. For verified kilometre figures and a downloadable GPS track, consult the official Via Alpina stage page.

Direction matters — walk southwest. The strongest practical recommendation for this stage is to walk it in the described direction (Rif. Città di Fiume → Pieve di Livinallongo), not reversed. The ascent to the Giau Pass from the Mondeval side is contained and well-graded; reversed, you face a sustained climb from the valley floor after a long and already demanding descent section. Walking southwest also means the full Marmolada panorama opens in front of you the moment you crest the pass — one of the great arrival moments on the entire Yellow Route. Book Rifugio Città di Fiume at least two to three weeks in advance in July and August; it accommodates both Via Alpina and Alta Via 1 walkers and fills fast at weekends.

Highlights & Points of Interest

• Mondeval Man archaeological site — In 1987, archaeologists uncovered a Mesolithic burial on the Mondeval plateau, dating to approximately 7,000 BCE. The male skeleton was interred with a deer-antler headdress, flint tools, and animal tooth ornaments — among the oldest and most complete Mesolithic burials found in the Alps. The site itself is unmarked, but the landscape context of the plateau makes the setting unmistakable.
• Rifugio Città di Fiume — The stage-start mountain hut positioned at approximately 1,913 m, above the Mondeval plateau in the Cadore region of Veneto. A classic CAI-affiliated rifugio with timber interiors, mountain-hut cuisine, and panoramic views across the surrounding peaks — the ideal base for the evening before B20.
• Giau Pass (Passo di Giau, 2,236 m) — One of the Dolomites' most photographed high points, the Giau sits above the treeline with an unbroken 360° view taking in Ra Gusela, Nuvolau, the Croda da Lago group, and — on clear days — the distant Marmolada glacier. A small bar and restaurant at the summit provides coffee, food, and a natural mid-stage rest.
• Marmolada (3,343 m) — The highest mountain in the Dolomites dominates the western horizon for much of the descent from the Giau Pass. Its retreating glacier catches the light above the valley, providing a constant navigational reference and a visual anchor for the long descent to Pieve di Livinallongo.
• Livinallongo del Col di Lana — A Ladin linguistic enclave, one of the distinctive cultural pockets of the Dolomites. Village signage is trilingual (Italian, German, Ladin), and the valley retains a pre-industrial character that sets it apart from more heavily touristed Dolomite destinations.
• Col di Lana — The forested ridge above Pieve di Livinallongo was among the most bitterly contested positions in the Dolomite front during WWI. Italian engineers detonated 35 tonnes of explosive beneath the Austrian summit position in April 1916, obliterating the hilltop. Hiking trails and memorial sites accessible from Pieve make this an optional extension for historically curious walkers.
• UNESCO Dolomites World Heritage Area — All of B20 falls within or adjacent to the UNESCO-listed Dolomite systems, a 142,000-hectare protected area spanning Belluno, South Tyrol, and Trentino. The designation specifically recognises the geological formations — pinnacles, towers, and pale cliffs of Dolomite limestone — that define every kilometre of this stage.
• Pieve di Livinallongo (Buchenstein) — The end-point village contains a 15th-century parish church, local guesthouses, and trailhead connections for onward stages of the Via Alpina Yellow Route. The nearby resort of Arabba, 4 km along the valley, provides a wider range of services and evening dining options.

Best Time to Hike the Via Alpina Yellow B20

The walking season for B20 runs from mid-June to late September, constrained by snow on the Giau Pass approach. At 2,236 m the pass can hold snow into June in heavy-winter years; by early July conditions are typically settled and the alpine wildflowers on the Mondeval plateau are at their peak.

July is the single best month. Days are long (sunrise before 5:30, sunset after 8:30), the trail is reliably snow-free, hut capacity is available with a few weeks' notice, and the sense of remoteness on the plateau has not yet been overtaken by August crowds. One non-negotiable caveat: afternoon thunderstorms build rapidly in the Dolomites in July and August. Plan to cross the Giau Pass by midday at the latest to avoid being above the treeline during storm build-up.

August brings the highest footfall across all Dolomites hut routes. Rifugio Città di Fiume and accommodation in Arabba fill weeks in advance. As of 2026, hut reservation systems across the Via Alpina in Italy allow online booking — use them. If August is unavoidable, weekdays are significantly quieter than weekends on this section of the route.

September offers the quietest trails, stable high-pressure windows, and autumn colour beginning on the valley slopes below the pass. Some rifugi close after mid-September; check Rifugio Città di Fiume's closing date directly before planning a late-season stage.

Avoid mid-October onwards. Snow returns to the Giau Pass, most huts have closed for the season, and the descent trail to Pieve di Livinallongo can become hazardous with early-season ice.

Practical Information

Accommodation

Two main accommodation nodes bracket the stage, with a limited option at the Giau Pass itself.

• Rifugio Città di Fiume — A CAI-affiliated mountain hut at the stage start, offering dormitory beds and private rooms. Expect approximately €35–50 per person in a shared dormitory with half-board (dinner and breakfast included), €70–90 for a private room. Advance reservation is essential from July onwards — book directly via the rifugio rather than through third-party platforms.
• Giau Pass summit — A small bar and restaurant with very limited overnight capacity, primarily a mid-stage rest point rather than a reliable overnight option. Do not count on accommodation here without confirming directly in advance.
• Pieve di Livinallongo — The end village has family-run hotels and guesthouses (pensioni) at approximately €70–110 per double room per night. The adjacent resort of Arabba, 4 km along the valley road, offers a broader selection including larger hotels, better restaurant options, and direct bus connections.

Getting There & Back

The stage is point-to-point, so transport logistics require planning in advance of arrival.

• To the start (Rifugio Città di Fiume): The nearest transport hub is Cortina d'Ampezzo, approximately 15–20 km away. Seasonal Dolomiti Bus services connect Cortina to the Giau Pass road, from which the trailhead is accessible on foot or by taxi. Venice Marco Polo Airport (VCE) is the closest major international gateway, approximately 2.5–3 hours by car. Car rental is the most practical option for reaching the trailhead, given the limited and seasonal bus frequency in this part of the Dolomites.
• From the finish (Pieve di Livinallongo / Arabba): Dolomiti Bus connects Arabba and Pieve di Livinallongo to Belluno (approximately 2 hours) and Cortina d'Ampezzo (approximately 50 minutes), with seasonal service frequency peaking in July and August. For 2026 timetables and route changes, check the Dolomiti Bus website directly before travelling.
• Car logistics: If self-driving, park at Pieve di Livinallongo (free parking near the village centre) the day before the stage and take a taxi or bus to the trailhead. Returning to your car by public transport or taxi avoids the complexity of managing two vehicles across a one-way route.

Permits & Fees

No walking permits are required for Via Alpina Yellow B20. The stage follows CAI-marked public trails through the Dolomites UNESCO World Heritage Site, which is freely accessible. There are no entry fees for the Mondeval plateau or the Giau Pass approach.

CAI membership (Club Alpino Italiano) earns 30–50% discounts on overnight stays in affiliated rifugi, including Rifugio Città di Fiume. Annual membership for non-Italian residents costs approximately €45–55. If you are walking multiple stages of the Via Alpina Yellow Route in Italy, membership pays for itself within two or three nights.

Gear & Packing List

B20 is a full mountain stage with a pass crossing at 2,236 m — pack for variable alpine conditions even in midsummer. The key decisions are pack volume, footwear, and weather protection.

For a single-stage carry without overnight kit, the Hyperlite Mountain Gear Aero 28 (536 g) is the lightest capable option — sufficient volume for a day's food, waterproofs, and insulation without unnecessary weight. For multi-day Via Alpina walking with a full overnight kit, the Deuter Aircontact Lite 45+10 (1,570 g) provides the structured back-panel support that sustained Dolomites terrain demands. Ultralight thru-hikers completing the full Yellow Route should consider the Zpacks Arc Blast 55L (450 g) — volume without weight penalty, well-suited to warm-season alpine conditions.

• Footwear: Stiff-soled mountain boots with ankle support. The Mondeval plateau is grassy, but the rocky terrain on the Giau Pass descent is unforgiving in trail runners, and wet conditions make the path slippery.
• Waterproofs: A hardshell jacket is non-negotiable. Afternoon thunderstorms build rapidly in the Dolomites from July onwards — the Giau Pass summit has no natural shelter beyond the summit bar.
• Insulation: A light down or synthetic jacket for the pass summit. Even on warm midsummer days, wind chill at 2,236 m during a rest break is significant.
• Sun protection: High-altitude UV in the Dolomites is intense from June through September. SPF 50+ sunscreen, UV-rated sunglasses (CE category 3–4), and a brimmed sun hat are as essential as your waterproof.
• Navigation: The Via Alpina Yellow Route is waymarked with yellow rhombus blazes, but carry a downloaded offline map or the Tabacco 1:25,000 map sheet 015 (Marmolada / Pelmo / Civetta) which covers this section in detail.
• Water and food: Water is available at Rifugio Città di Fiume at the start and the bar at the Giau Pass summit. The Mondeval plateau may have seasonal streams — treat all open water sources. The Giau bar is the only guaranteed mid-stage resupply, so carry enough food for the full stage independently.

Frequently Asked Questions

When is the best time to hike Via Alpina Yellow B20?

July is the best single month. The Giau Pass (2,236 m) is reliably snow-free by early July, days are long and wildflowers on the Mondeval plateau are at their peak. August works but huts and village accommodation fill weeks in advance and the Giau Pass road sees heavy tourist traffic. September is quieter with stable weather windows, though some rifugi close by mid-month — verify Rifugio Città di Fiume's closing date before planning a late-season stage. Avoid October onwards when snow returns to the pass.

How difficult is Via Alpina Yellow B20?

B20 is a demanding alpine stage suited to experienced day hikers comfortable on open mountain terrain. The route includes a significant pass crossing at 2,236 m and a long descent with cumulative elevation change. The terrain is non-technical — no scrambling, no via ferrata — but requires solid cardiovascular fitness, appropriate mountain boots, and the judgement to manage afternoon weather risk on the pass. It is not suitable for casual walkers in road shoes or hikers without prior alpine experience.

How far can you realistically hike per day on this stage?

Via Alpina stages in the Dolomites are planned as full-day undertakings of approximately 5–8 hours of walking. Most fit hikers complete B20 as a single day, spending the preceding night at Rifugio Città di Fiume and the following night in Pieve di Livinallongo or Arabba. The stage is not designed to be split mid-route, though the Giau Pass bar provides a natural rest point at the highest elevation of the day. Pace conservatively on the Mondeval plateau — the descent from the pass is longer than it looks from the summit.

What accommodation is available on Via Alpina Yellow B20?

The primary options are Rifugio Città di Fiume at the start (approximately €35–50 per person in dormitory with half-board) and guesthouses or hotels in Pieve di Livinallongo and Arabba at the end (approximately €70–110 per double room). Book Rifugio Città di Fiume at least two to four weeks ahead in July and August — it is a popular overnight stop for both Via Alpina and Alta Via 1 walkers and fills quickly on weekends. No established camping sites exist along the stage route itself.

Do you need permits to hike Via Alpina Yellow B20?

No permits are required. The stage follows CAI-marked public trails through the Dolomites UNESCO World Heritage Site, which is freely and openly accessible. No fees apply for the Mondeval plateau or Giau Pass crossing. CAI membership (approximately €45–55 per year for non-Italian residents) is optional but earns 30–50% discounts at affiliated rifugi — worthwhile for anyone walking more than two or three stages of the Via Alpina in Italy during a single trip.
