One of the world's great long-distance hikes traversing the UNESCO-listed Dolomites' iconic pale limestone towers, meadows, and wartime via ferrata routes. Connected rifugi provide overnight accommodation and hearty Tyrolean meals.
Alta Via 1 is a multi-day high-altitude traverse of the western Dolomites, running approximately 120 km from Lago di Braies (Pragser Wildsee) in the north to Belluno in the south — or walked in the opposite direction. The route crosses a UNESCO World Heritage Site of world-famous pale limestone spires, glacial cirques, meadows carpeted with alpine wildflowers, and preserved World War I tunnel and trench systems from the 1915–1918 Alpine Front.
Most walkers begin at Lago di Braies, reachable by bus from Dobbiaco (Toblach) station on the Innichen–Fortezza railway line in South Tyrol. Dobbiaco is served by trains from Verona, Bolzano, and Innsbruck. Private vehicles can be left at the Lago di Braies car park (fee applies), though summer access is restricted to early morning and evening — shuttle buses operate from Dobbiaco during peak hours. No special permits are required to hike the route.
The standard itinerary divides into 7–10 daily stages. Key overnight stops include Rifugio Biella, Rifugio Lagazuoi (accessible from Cortina d'Ampezzo), Rifugio Nuvolau, and Rifugio Pian de Cengia, all at altitudes between 2,000 m and 2,750 m. The Tre Cime di Lavaredo circuit can be incorporated near the midpoint as an iconic day-detour to one of the Dolomites' most photographed formations. Wartime history is a recurring element: near Monte Lagazuoi, Italian and Austrian military tunnels from the Alpine Front are accessible and form a dramatic walking corridor.
The trail is marked with red-white blazes and numbered Alta Via 1 waymarkers. Terrain varies considerably: grassy alpine meadows, exposed rocky ridges, scree slopes, and short via ferrata (aided climbing) sections near exposed cliff passages. A harness and via ferrata set — available for hire in Cortina d'Ampezzo — are recommended for the more exposed aided sections. Weather changes rapidly; afternoon thunderstorms are a regular occurrence from July onwards.
Rifugi along the route provide accommodation in shared dormitories or private rooms, traditional Tyrolean and Italian meals including Schlutzkrapfen pasta and Kaiserschmarrn, and the communal atmosphere that defines the Alta Via experience. Bookings are essential from June through September; weekends fill months in advance. Water is available at rifugi and some marked fountains; purification tablets are advisable for stream water.

Tips for visiting
- Book all rifugi at least 2–3 months ahead for July–August; many fill entirely by April and cannot accommodate walk-ins.
- Carry a via ferrata harness and set for exposed sections near Monte Lagazuoi; rental is available from outdoor gear shops in Cortina d'Ampezzo.
- Plan arrival at Lago di Braies before 08:00 or after 18:00 in summer — the shuttle system limits midday private vehicle access.
- Pack layers even in summer: summit temperatures at 2,500 m can fall below 5°C in the early morning and after afternoon storms.
- Trekking poles significantly ease the scree descents; gaiters are useful after rain on loose trail sections.
When to visit
Mid-June to early October when rifugi are open and passes are largely snow-free. September is particularly recommended for autumn colours, crisp visibility, and noticeably reduced crowds compared to the July–August peak.
Accessibility
Not accessible for wheelchair users or strollers. The trail involves multi-day alpine terrain with significant cumulative elevation gain and loss, scree, boulder fields, and exposed via ferrata sections across its 120 km length.
Frequently asked questions
How long does Alta Via 1 take to complete?
Most hikers complete the full 120 km in 7 to 10 days depending on fitness and optional detours such as the Tre Cime di Lavaredo circuit. Shorter versions are possible by joining or leaving the route at Cortina d'Ampezzo.
Is Alta Via 1 a technical climbing route?
The main trail does not require technical climbing skills, but several sections pass exposed ridges and short via ferrata passages that benefit from a harness and ferrata set. Confident scramblers without equipment may manage with care on the easier aided sections.
When do rifugi on the route open and close?
Most rifugi open from mid-June to late September or early October, subject to early or late-season snowfall. Individual opening dates vary; confirm directly with each rifugio before finalising departure dates.
What is the best direction to walk Alta Via 1?
South to north (Belluno toward Braies) ends with the scenic Lago di Braies. North to south (Braies toward Belluno) ends near the city with straightforward bus or taxi options. Both directions are equally well waymarked.
Are there bailout options if weather deteriorates mid-route?
Yes. Cortina d'Ampezzo, Alleghe, and Selva di Cadore all lie within a short descent of the route and have road access and taxi services, making evacuation straightforward at multiple points along the traverse.
