120 kilometers (75 miles). From Lago di Braies to Belluno, through the heart of the UNESCO Dolomites. The Alta Via 1 is the most famous hut-to-hut trek in the Italian Alps — and one of the few that genuinely lives up to its reputation.
Every summer, thousands of hikers walk these trails from north to south, sleeping in rifugios, eating at 6,500 feet, crossing landscapes that shift character completely from one day to the next. This guide covers everything you need to plan it properly: stages, difficulty, timing, rifugios, and how to actually make it happen.
The UNESCO Dolomites along the Alta Via 1 — 120 km (75 miles) north to south.

What the Alta Via 1 is
The Alta Via 1 — known in German as the Dolomiten Höhenweg 1 — is the first and most celebrated of the ten "high routes" crossing the Dolomites from north to south. It starts at Lago di Braies (Pragser Wildsee) in South Tyrol and ends at Belluno in the Veneto, passing through some of the most iconic mountain groups in the eastern Alps: Fanes-Sennes, Lagazuoi, Cinque Torri, Pelmo, Civetta.
It's the most scenic and least technical of the Dolomite high routes. No via ferrata gear required, trails are continuously marked, and rifugios are spaced to make stages manageable for well-prepared hikers. That said, it isn't easy: nearly 23,000 feet of cumulative elevation gain over 9–10 days demands fit legs and genuine respect for alpine terrain.
Route data and stages
The classic route runs 10–11 stages. The northern sections — from Braies through Cortina — are the most visited and visually spectacular. The southern stages — through the Belluno Dolomites toward Belluno — become wilder, quieter, with more rustic rifugios and a completely different character.
| Stage | From → To | Miles / km | Gain | Hours |
|---|---|---|---|---|
| 1 | Lago di Braies → Rif. Biella | 7.5 mi / 12 km | 3,770 ft / 1,150 m | 6–7 h |
| 2 | Rif. Biella → Rif. Lavarella | 6 mi / 10 km | 2,625 ft / 800 m | 5–6 h |
| 3 | Rif. Lavarella → Rif. Lagazuoi | 9 mi / 14 km | 3,115 ft / 950 m | 6–7 h |
| 4 | Rif. Lagazuoi → Rif. Cinque Torri | 7 mi / 11 km | 2,130 ft / 650 m | 4–5 h |
| 5 | Rif. Cinque Torri → Rif. Nuvolau | 5.5 mi / 9 km | 2,460 ft / 750 m | 5–6 h |
| 6 | Rif. Nuvolau → Rif. Città di Fiume | 6 mi / 10 km | 1,640 ft / 500 m | 4–5 h |
| 7 | Rif. Città di Fiume → Rif. Palafavera | 7.5 mi / 12 km | 2,300 ft / 700 m | 5–6 h |
| 8 | Rif. Palafavera → Rif. Vazzoler | 8 mi / 13 km | 2,790 ft / 850 m | 6–7 h |
| 9 | Rif. Vazzoler → Rif. Carestiato | 6 mi / 10 km | 1,800 ft / 550 m | 4–5 h |
| 10 | Rif. Carestiato → Rif. Pramperét | 6 mi / 10 km | 1,640 ft / 500 m | 5 h |
| 11 | Rif. Pramperét → Belluno | 9 mi / 14 km | 985 ft / 300 m | 5–6 h |
Stages 3–5, covering the Lagazuoi–Cinque Torri–Nuvolau area, are the most photographed and iconic on the entire route. The area around Monte Lagazuoi is also an open-air World War I museum: tunnels carved through the rock during the conflict are still walkable and tell one of the most striking chapters of alpine military history.
Shorter versions
Don't have 10 days? The northern section (Lago di Braies → Cortina, 4–5 days) is the most spectacular and logistically straightforward. The Cortina → Civetta section (5–6 days) shifts into something wilder and less crowded. Both work as complete treks in their own right.
Difficulty and preparation
The Alta Via 1 is rated moderate to demanding on international hiking scales — comparable to a multi-day route in the Colorado Rockies or Sierra Nevada, with sustained elevation and technical terrain that demands attention. No rock climbing or scrambling is required, but the trail crosses steep scree fields, exposed ridges, and sections with fixed cables on the most technical passages.
The most technically demanding sections are Forcella di Lago (steep, loose scree descent), the Lagazuoi Galleries (exposed rocky traverse), and Cima de Zita near the end — a ridge with a drop on both sides. All can be managed with proper footwear and a calm head. Bypasses exist, but most hikers who arrive prepared don't need them.
Training matters: plan at least 6–8 weeks of specific preparation — not flat walking, but sustained elevation gain. Hikers comfortable on multi-day trails in the Rockies or Sierra Nevada will find their footing quickly. Those starting from zero will feel it by day one.
Essential gear
- Broken-in hiking boots — ankle support, Vibram sole. Not trail runners.
- Trekking poles — essential on scree descents and exposed sections
- Waterproof jacket — mountain weather shifts in minutes at altitude
- Sleep sheet / liner — required in most rifugio dormitories
- 30–40 L daypack — ideal weight under 22 lbs / 10 kg (with luggage transfer: 11–15 lbs / 5–7 kg)
- High SPF sun protection — UV exposure above 6,500 ft / 2,000 m is intense
- Tabacco 1:25,000 topo maps — sheets 031, 03, 025 cover the full route
When to go
The window is narrow: mid-July to mid-September. Before that, snow remains on the higher passes. After mid-September, weather turns unstable and many rifugios close.
August is the busiest month — the northern rifugios (Lagazuoi, Cinque Torri, Nuvolau) are full, and the trails near the most famous landmarks see heavy traffic. Mid-July and September offer the same landscapes with fewer people, cooler temperatures, and a quieter experience overall.
Booking rifugios in advance
Rifugios open reservations from August of the previous year. The most popular ones — Lagazuoi, Nuvolau, Cinque Torri — fill up within days of opening for August dates. July and September have slightly more availability, but not much. If you're planning a summer trek, start booking in winter.
The rifugios along the route
The Alta Via 1 rifugios are among the most distinctive structures in the Italian Alps. In the northern section — Braies to Cortina — standards are high: private rooms available, quality mountain cooking, panoramic terraces with 360° views. In the southern section — Belluno Dolomites onward — rifugios become more rustic, quieter, with an authenticity many hikers prefer.
Every rifugio serves dinner and breakfast. The cooking is alpine: polenta, canederli (bread dumplings), game, thick soups. Rifugio Lagazuoi at 9,029 ft / 2,752 m is considered one of the finest in the eastern Alps — at sunrise, the Cortina Dolomites turn a shade of orange that no photograph fully captures.
Dormitories or private rooms? Most rifugios offer both. Private rooms book out first. If you want a room to yourself, book rooms specifically — not just a bed — and do it months in advance.
How to organize it
There are three approaches to the Alta Via 1:
1. Fully independent (DIY)
You manage all rifugio bookings, maps, transport, and luggage logistics yourself. Requires time, some Italian for phone bookings, and solid alpine experience. Possible — but the most popular rifugios require months of advance booking, flexibility when weather forces plan changes, and comfort navigating alpine terrain on your own.
2. Self-guided with full support
Rifugios pre-booked, day-by-day itinerary, paper and GPS maps, luggage transfer between stages, and 24-hour phone support throughout. You hike with whoever you choose, at your own pace. All logistics are already handled — you focus entirely on the trail.
3. Guided
Same complete organization as self-guided, with a local guide walking with you every day. They know the weather patterns, the route variations, the history of the WWI tunnels at Lagazuoi, the geology behind the Cinque Torri. For those who want to understand the terrain as they cross it — not just cross it.

Guided or self-guided — your call.
Rifugios booked, daily itinerary, paper and GPS maps, luggage transfer, 24h support. You walk — we handle the rest.
Same full organization, with a guide who brings the territorial knowledge no map can give you — history, geology, alpine culture.
What to bring — and what to leave behind
Luggage transfer is available on both organized options: your main bag travels from rifugio to rifugio, you carry only a daypack. Trail weight drops to 11–15 lbs / 5–7 kg — a difference you'll feel clearly on the first scree descent.
What not to bring: "just in case" clothing you won't use, non-essential electronics, paper books. Every extra pound feels heavier on day 7 than it did on day 1.
Frequently Asked Questions
How difficult is the Alta Via 1?
It's a moderate-to-demanding alpine trek. No technical climbing or via ferrata gear is required, but the terrain is varied and exposed in places. Think multi-day Colorado Rockies hiking with full packs and sustained elevation. Plan 6–8 weeks of specific training with elevation gain before you go.
How many days does the Alta Via 1 take?
The full route (120 km / 75 miles) takes 9–11 days depending on pace and rest days. Shorter versions are available: the northern section (Braies to Cortina, 4–5 days) or the central section (Cortina to Civetta, 5–6 days) work as standalone treks.
When do rifugio bookings open?
Rifugios generally open reservations from August of the previous year. The most popular ones fill within days for August dates. July and September have slightly better availability — but don't count on it. If you're planning a summer trek, book in winter.
Can I hike the Alta Via 1 without a guide?
Yes. Trails are well-marked and the route doesn't require a guide for safety reasons. A guide adds territorial knowledge — WWI history, geology, local culture — and real-time weather judgment. Not essential, but for many it transforms the trek from a crossing into an understanding.
How far in advance should I book?
For August: 6–8 months ahead. For July and September: 3–4 months. If you organize through Dolomist, the team handles all rifugio bookings — including the hardest ones to secure.
How do I get to Lago di Braies?
Most international hikers fly into Venice or Bolzano, then take a bus to Dobbiaco and a shuttle to Lago di Braies (private car access is restricted in summer). Expect 4–5 hours total from Venice. Dolomist provides full arrival instructions and trailhead transfer logistics.
