The Alta Via 1 runs 120 km from Lago di Braies to Belluno in 7–10 days, linking staffed refugios through the heart of the Dolomites. It is a waymarked trail suitable for fit hikers with no technical climbing required, but the terrain is relentlessly steep and the refugios need to be booked weeks — sometimes months — in advance for July and August.
The Dolomites are among the most dramatic mountain ranges in Europe: pale limestone towers, candy-pink at dusk, rising from meadows of wildflowers. The Alta Via 1 was laid out in the 1960s to connect the best of them in one continuous route. Unlike a point-to-point trail that repeats access roads, the AV1 stays high — above 2,000 m for much of its length — moving from one valley to the next through saddles, scree slopes and the occasional fixed chain. What follows is the day-by-day breakdown, with real refugio names, transport notes and the seasonal details that matter.
Is the Alta Via 1 right for you?
This is a sustained mountain route, not a leisurely walk. You will gain and lose 400–800 m on most days. The path is well marked (red-and-white blazes, waypoint 1) and mostly on trail, but several sections involve scrambling and short via ferrata passages. No harness is needed, but you must be comfortable with exposed terrain and a full pack. The refugios vary from rustic dormitories (6–10 per bunk room) to small private rooms; showers are coin-operated, and dinner is shared at communal tables. This is a hut-to-hut experience, not wild camping — bring a sleeping bag liner, not a tent.
The Alta Via 1 day by day
Day 1 — Lago di Braies to Rifugio Biella (4–5 hours, ~700 m up / 500 m down). The trail starts at the turquoise Lago di Braies, a car park you reach by bus from Dobbiaco or Brunico. The first day climbs steeply through pine forest to the Forcella Sora Forno pass, then descends to the Rifugio Biella at 2,327 m, the highest on the whole route. Arrive before 17:00 — dinner is served at a fixed time and the kitchen does not wait.
Day 2 — Rifugio Biella to Rifugio Lagazuoi (5–6 hours, ~700 m up / 900 m down). A long traverse above the Fanes plateau passes the Rifugio Fanes and the smaller Rifugio Lavarella before the final climb to Lagazuoi at 2,752 m, reachable by cable car from Passo Falzarego if legs give out. The sunset from Lagazuoi, looking west toward the Marmolada, is the visual highlight of the entire route.
Day 3 — Rifugio Lagazuoi to Rifugio Cinque Torri (3–4 hours, easy). A short day — useful for rest or for exploring the World War I tunnels carved into the Lagazuoi massif (the refugio has a small WWI museum). Descend to Passo Falzarego, cross the road, and climb to the spires of the Cinque Torri, five limestone columns beloved by climbers and photographers. The refugio here is the most accessible on the route (reachable by chairlift) and consequently the busiest.
Day 4 — Cinque Torri to Rifugio Croda da Lago (4–5 hours, ~600 m up). The route crosses Passo Giau (2,236 m), one of the great cycling climbs in the Dolomites and a panoramic vantage point for the Pelmo and Civetta massifs. The descent to Rifugio Croda da Lago, perched above the lake of the same name, takes another hour. This is a quieter, wilder section — fewer day-trippers, more chamois.
Day 5 — Rifugio Croda da Lago to Rifugio Coldai (5–6 hours, ~900 m up). The longest climb of the route ascends the northwest face of Civetta — "the wall of walls" — and reaches the Rifugio Coldai at 2,191 m. The views from the descent toward Alleghe are across the full south face of Civetta, a vertical kilometre of dolomite.
Day 6 — Rifugio Coldai to Rifugio Vazzoler (4–5 hours). A gentler day descends through Val Corpassa forest to the Rifugio Vazzoler, one of the oldest on the route and set in beech woodland below the Moiazza group. This is a good day for sore knees — pack trekking poles.
Day 7 — Rifugio Vazzoler to Rifugio Carestiato (5–6 hours, ~800 m up). The route climbs back above the treeline over Forcella Col dell'Orso and continues to the Rifugio Carestiato. The terrain here becomes gentler, the villages closer — the Dolomites are giving way to the pre-Alps.
Day 8 — Rifugio Carestiato to Belluno (4–5 hours, mostly downhill). The final day descends to the city of Belluno in the Piave valley. Buses connect Belluno to Venice (2 hours), Padova and the main rail network. Many hikers take an afternoon train and are in Venice for dinner.
When should you go?
The refugios open between mid-June and late September, with the core season running July to mid-September. Late June and early September are the best windows: snow has usually cleared the high passes, the refugios are open, and the worst of the summer crowds have not yet arrived (or have gone home). July and August are spectacular but very busy — expect full dormitories, advance booking essential, and the Cinque Torri chair lift queues. Outside the season, most refugios close and the passes can hold snow into October; the route becomes a mountaineering undertaking, not a hike.
Where do you sleep?
Every night is in a staffed refugio. The main ones, in order, are: Rifugio Biella, Rifugio Lagazuoi, Rifugio Cinque Torri, Rifugio Croda da Lago, Rifugio Coldai, Rifugio Vazzoler, Rifugio Carestiato. All offer half-board (dinner + bed + breakfast) and most have showers (€2–3 coin-op). Prices run €50–80 per person for half-board. Book directly with each refugio — most have email or an online form on their own website; the CAI (Club Alpino Italiano) website lists them all. For July and August, book 6–8 weeks out minimum. The Rifugio Lagazuoi and Cinque Torri fill fastest.
What should you pack?
- Sleeping bag liner (refugios provide blankets but many hikers prefer their own liner)
- Lightweight hiking boots — trail runners are fine for fit hikers; full ankle support for anyone with a heavy pack or uncertain ankles
- Trekking poles — the descents are long and your knees will thank you from day 3
- Layers: mornings above 2,000 m are cold even in August; a down jacket earns its weight
- Waterproof jacket: afternoon thunderstorms are common in July and August
- Cash: many refugios don't take cards reliably; €200 for the whole route is enough
- Water capacity for 3–4 hours: water sources are plentiful but not at every pass
How do you get to Lago di Braies?
The start point, Lago di Braies, is in the Dolomites of Alto Adige (South Tyrol). The nearest airports are Innsbruck (1.5 hours), Venice (2 hours) and Verona (2 hours). From Venice or Verona, take a train to Brunico, then a bus to Dobbiaco, then the mandatory shuttle bus to Lago di Braies — private cars are banned from the lake road in season. From Innsbruck, bus services run into the Pustertal valley. To return from Belluno, frequent buses run to Venice Santa Lucia station (around €10, 2 hours).
Is it worth it?
Yes — if you want the best of the Dolomites in one continuous trip rather than day hikes from a valley base. The AV1 gives you the variety (plateau, tower, glacier, forest, war history) without requiring technical climbing, and the refugio culture — the shared tables, the early starts, the other long-distance hikers — is a significant part of the experience. Go in late June or early September and you will have the best views in the Alps at a fraction of the crowd levels. The one honest warning: the refugio booking is the real work, and it needs to happen months before you fly.
