Alta via n. 1 delle Dolomiti - Dolomiten-Höhenweg Nr. 1
The Alta via n. 1 delle Dolomiti (Dolomiten-Höhenweg Nr. 1) is a 125 km point-to-point trail in the Dolomites of northern Italy, gaining roughly 7,300 m of elevation over 12 days. Rated moderate, it is the classic and most accessible of the Dolomite high routes, linking Lago di Braies to Belluno through five mountain groups without obligatory technical climbing.
About the Alta via n. 1 delle Dolomiti - Dolomiten-Höhenweg Nr. 1
The Alta Via 1 is the original and best-loved of the Dolomite high routes, first promoted in the 1960s as a way to thread the great limestone massifs of the eastern Alps into a single continuous walk. Running 125 km from the turquoise Lago di Braies at 1,494 m to the valley town of Belluno at 694 m, it crosses five distinct mountain groups: the Dolomiti di Braies, the Gruppo di Fanis, the Dolomiti Ampezzane, and the northern and southern Dolomiti di Zoldo.
Unlike its tougher siblings, the route carries no compulsory via ferrata. The trail is waymarked throughout with a blue triangle enclosing the number "1", and most walkers complete it in 8 to 12 days depending on how many stages they combine. The highest point is Rifugio Lagazuoi at 2,752 m, perched on a ridge riddled with First World War tunnels. Because the entire path is served by manned mountain huts (rifugi), there is no need to carry a tent or full camping kit, which keeps pack weight low and the daily rhythm civilised.
Recognised as a Regional Walking Network (RWN) route of regional significance, the Alta Via 1 sits within UNESCO-listed Dolomite landscapes. The cumulative climbing of around 7,300 m is spread across the full distance, so individual days rarely exceed 1,000 m of ascent — demanding, but achievable for any fit hiker comfortable with long days on rocky mountain terrain.

The 12 classic stages below follow the standard south-bound itinerary from Lago di Braies to Belluno. Daily climbing and walking times come from the established hut-to-hut schedule; strong walkers routinely merge stages to finish in 8 to 9 days.

Highlights & Points of Interest
- Lago di Braies (1,494 m) — The trailhead is one of the most photographed lakes in the Alps, its glassy turquoise water backed by the Croda del Becco. Start early to beat the day-tripper crowds.
- Fanes high plateau — A vast karst tableland of grazing meadows and dwarf pine, rich in Ladin folklore and home to marmots and chamois.
- Rifugio Lagazuoi (2,752 m) — The route's highest point and a living open-air museum of the 1915–1917 mountain war, with restored tunnels bored straight through the rock.
- Cinque Torri — Five iconic rock towers near Rifugio Nuvolau, beloved by climbers and ringed by reconstructed front-line trenches.
- Monte Pelmo (3,168 m) — "Il Caregón del Padreterno" (God's Armchair) dominates the central stages, its bulk visible for days.
- Monte Civetta (3,220 m) — The northwest wall above Rifugio Coldai is one of the largest rock faces in the Dolomites, glowing red at sunset.
- Lago Coldai — A small alpine tarn beneath Civetta that mirrors the peak on still mornings — a classic photo stop on Stage 7.
- Schiara group & Gusela del Vescovà — The final massif before Belluno, where the slender Gusela rock needle marks the optional ferrata finish.
Best Time to Hike the Alta via n. 1 delle Dolomiti - Dolomiten-Höhenweg Nr. 1
The walking season runs from mid-June to late September, the window in which the rifugi are staffed and open. Snow can linger on north-facing slopes and high passes into early July, so the safest, most reliable conditions arrive from mid-July onward. As of 2026, most huts publish opening dates around 20 June and close in the third week of September; confirm directly before booking shoulder-season nights.
The single best month is September. Early-autumn weather in the Dolomites brings stable high pressure, crisp clear air with the longest mountain views, sharply reduced crowds after the Italian August holidays, and cool but comfortable walking temperatures of roughly 8–18 °C at hut altitude. July and August offer the warmest days and the most reliably open infrastructure, but they also bring the heaviest foot traffic, the highest hut prices, and frequent afternoon thunderstorms that build over the peaks from around 2 pm — start each stage early to be off exposed ridges before they arrive.
Practical Information
Accommodation
The Alta Via 1 is a hut-to-hut trek: you sleep in CAI (Club Alpino Italiano) and privately run rifugi each night, which means a sleeping-bag liner replaces a tent and sleeping bag. Expect to pay roughly €60–80 per person for half-board (dinner, bed and breakfast) in a shared dormitory, with CAI members and reciprocal alpine-club members receiving a discount on the bed portion. A private double room, where available, costs more. Wild camping is prohibited within the protected park zones, though a discreet bivouac near unmanned shelters such as Bivacco Marmol is tolerated for self-sufficient walkers.
Booking is essential in July and August — popular huts like Lagazuoi, Nuvolau and Coldai fill weeks ahead. Carry enough cash, as card payment is unreliable at remote refuges, and budget around €15–25 for a packed lunch and drinks each day on top of half-board.
Getting There & Back
The nearest international airports are Venice Marco Polo (about 2.5 hours by road from the start) and Innsbruck. To reach the trailhead at Lago di Braies, take a train to Villabassa/Niederdorf or Dobbiaco/Toblach on the Fortezza–Lienz line, then the seasonal SAD bus 442 to the lake (around 30 minutes). From the finish at Belluno, the railway station offers direct regional trains to Venice (roughly 2 hours), Padua and the wider network. Linking start and finish by public transport takes a half-day, so build a travel buffer into your itinerary.
Permits & Fees
No permit is required to walk the Alta Via 1, and there is no trail fee. Access to the path is free; your only fixed costs are hut nights, meals and transport. A nice tradition: collect a stamp at each rifugio and present your card at the Tourist Information Office on Piazza Duomo in Belluno to register your completion and receive a commemorative pin. Standard alpine insurance covering mountain rescue is strongly recommended.
Gear & Packing List
Because you sleep indoors every night, the Alta Via 1 is an ideal route for a light, fast setup. A 35–50 litre pack is plenty: leave the tent at home and carry a sleeping-bag liner, layered clothing for 5–20 °C swings, waterproofs, sturdy B-rated hiking boots, trekking poles for the long descents, and a helmet plus light harness only if you intend the optional Marmol ferrata. A frameless ultralight pack such as the 2400 Windrider suits minimalist walkers, while the larger 3400 Windrider or a comfort-focused Atmos AG 50 gives more room for layers and food.

Frequently Asked Questions
When is the best time to hike the Alta Via 1?
The season runs mid-June to late September while the rifugi are open. September is the best single month: stable high-pressure weather, the clearest long-distance views, far fewer crowds than the August peak, and comfortable temperatures of about 8–18 °C. July adds warmth and full hut availability but brings reliable afternoon thunderstorms.
How difficult is the Alta Via 1?
It is rated moderate and is the most accessible of the Dolomite high routes, with no obligatory via ferrata. The terrain is rocky and the days are long, but a reasonably fit hiker comfortable with exposure on marked mountain paths can complete it. Only the optional Marmol ferrata descent near the end involves graded climbing, and it can be bypassed.
How many kilometres do you walk per day?
Across the classic 12 stages the 125 km route averages about 10–12 km per day, with 4 to 6 hours of walking and 260–1,070 m of ascent. The modest daily distance reflects steep, rocky terrain rather than easy ground. Fitter walkers combine stages to finish in 8 to 9 days, pushing daily figures to 15–20 km.
Where do you sleep on the trail?
You stay in mountain huts (rifugi) every night, so no tent is needed — just a sleeping-bag liner. Half-board (bed, dinner and breakfast) costs roughly €60–80 per person, with alpine-club members paying less for the bed. Huts along the busy northern stages such as Lagazuoi and Nuvolau must be booked well ahead in July and August.
Do you need a permit to hike the Alta Via 1?
No permit is required and there is no trail fee — access to the path is free. Your costs are limited to hut nights, meals and public transport. Carry cash, as card payment is unreliable at remote refuges, and arrange alpine insurance that covers mountain rescue. Collecting hut stamps earns a commemorative completion pin in Belluno.
