Alta via n. 9 delle Dolomiti - Dolomiten-Höhenweg Nr. 9

The Alta Via n. 9 delle Dolomiti (Dolomiten-Höhenweg Nr. 9) is a 140 km point-to-point high route in the Dolomites of northern Italy, gaining roughly 8,200 m of elevation over 7 days. Rated challenging, it is the longest and least-travelled of the classic Dolomite traverses, crossing five distinct mountain groups from Cadore to the Catinaccio.

About the Alta via n. 9 delle Dolomiti - Dolomiten-Höhenweg Nr. 9

Nicknamed "La Trasversale" for the way it cuts sideways across the entire Dolomite range, the Alta Via n. 9 runs 140 km from Danta di Cadore in the province of Belluno to Bagni di Lavinia Bianca near Tires (Tiers) in South Tyrol. Where the famous Alta Via 1 and Alta Via 2 run roughly north to south, the number 9 travels east to west, threading together five of the most celebrated massifs in the Alps in a single continuous line.

The route is one of the dozen numbered Alte Vie (high routes) that were waymarked across the Dolomites from the 1960s onward, linking existing mule tracks, military paths from the First World War and shepherds' trails into multi-day itineraries served by manned rifugi (mountain huts). The Alta Via 9 is the longest of them and sees a fraction of the foot traffic of its better-known siblings, which makes it a magnet for hikers who already know the Dolomites and want quieter ground. The entire corridor sits inside the Dolomites UNESCO World Heritage Site, inscribed in 2009 for its geological and scenic value.

Across its seven stages the trail climbs to exposed passes above 2,500 m, drops into wooded valleys, and passes beneath landmark walls such as the Croda dei Toni, the Cristallo, the Tofane, the Sella and the Catinaccio (Rosengarten). It is a serious undertaking: most days involve 1,000–1,500 m of ascent on rough, sometimes cabled terrain, and a head for heights helps on the higher sections. The reward is a cross-section of the whole range in a single trek.

Route Overview & Stages

The classic itinerary breaks the 140 km into seven hut-to-hut stages. Distances and ascent figures below are approximate and assume the standard west-bound direction starting in Cadore; strong walkers sometimes combine stages, while those carrying full packs may want a rest day in Cortina or at Passo Pordoi.

Total: roughly 140 km and about 8,200 m of cumulative ascent. Daily walking time runs from 5 to 8 hours depending on stage length and conditions.

Highlights & Points of Interest

• Croda dei Toni (Zwölferkofel), 3,094 m — the soaring three-summit massif that dominates stages 1 and 2, a defining silhouette of the eastern Dolomites.
• Cadini di Misurina — a maze of slender limestone needles between Misurina and the Tre Cime, reached around Rifugio Fonda Savio and one of the most photographed corners of the range.
• Tre Cime di Lavaredo — the iconic trio is not climbed by the route but stays in view across stages 2–4, an unmistakable landmark of the World Heritage area.
• Lake Misurina, 1,754 m — a turquoise alpine lake ringed by the Sorapiss and Cristallo, a natural midpoint and resupply spot.
• Cristallo group — crossed via high forcelle on stage 4, riddled with First World War tunnels and via ferrata installations above Cortina.
• Cortina d'Ampezzo & the Tofane — the Dolomites' best-known resort sits below the route on stage 5, beneath the 3,244 m Tofana di Mezzo.
• Sella massif & Passo Pordoi, 2,239 m — a vast fortress of rock circled by the great Dolomite passes, the high pivot point of the traverse.
• Catinaccio / Rosengarten — the legendary "rose garden" wall that glows pink at sunset (the enrosadira), the grand finale before the drop to Tires.

Best Time to Hike the Alta via n. 9 delle Dolomiti - Dolomiten-Höhenweg Nr. 9

The hiking window is short and tied to when the high rifugi are open and the snow has cleared from the passes. Most huts on the route operate from around 20 June to late September, and the upper forcelle above 2,500 m can hold old snow into early July.

Early-to-mid September is the single best month to walk the Alta Via 9. By then the snow is gone, summer thunderstorms have eased, the air is clearer for long views across five groups, hut crowds thin out after the Italian holiday peak, and the first larches begin to turn gold. July offers the longest daylight but the highest thunderstorm risk and the busiest huts around the Sella and Cortina. August is reliably warm but coincides with peak Italian and German holidays, so book beds well ahead. As of 2026, alpine weather remains volatile in the Dolomites: afternoon thunderstorms are common from late June through August, so plan early starts and check the local forecast each morning. Late September can bring the first snowfalls and several huts begin closing in the final week, so confirm opening dates before you set off.

Practical Information

Accommodation

The Alta Via 9 is a hut-to-hut route: you sleep in manned CAI (Club Alpino Italiano) and South Tyrolean rifugi rather than carrying a tent. Expect a bunk in a shared dormitory plus dinner and breakfast (mezza pensione, half-board) for roughly €60–€80 per person per night; a dormitory bed alone runs about €25–€35, with CAI members paying reduced rates. Huts named along the route include Rifugio Berti, Rifugio Carducci, Rifugio Fonda Savio, Rifugio Son Forca, Rifugio Pralongià and Rifugio Friedrich August, plus the Alpe di Tires hut near the finish. Booking is essential in July and August — phone or email each hut directly and reconfirm a day ahead. Bring a sleeping-bag liner (required by most huts), cash for extras, and earplugs for the dorms. Wild camping is restricted across the Dolomites and not a substitute for the hut network.

Getting There & Back

The eastern trailhead at Danta di Cadore / Santo Stefano di Cadore is reached by bus from Calalzo di Cadore, the nearest railway station (Trenitalia regional line from Venice, around 3 hours from Venezia Santa Lucia). From the western finish at Tires/Tiers, regular buses run to Bolzano (Bozen), about 30–40 minutes away, which sits on the main Verona–Brennero railway. The most convenient airports are Venice Marco Polo (VCE) for the start, roughly 2.5–3 hours by train and bus, and Verona (VRN) or Innsbruck (INN) for the Bolzano end. SAD/SüdtirolMobil and Dolomitibus operate the regional bus links; a point-to-point traverse like this makes public transport far simpler than trying to return to a parked car.

Permits & Fees

No permit is required to walk the Alta Via 9 — the trails are open public mountain paths. There is no entry fee for the Dolomites UNESCO area itself. Your main costs are hut half-board, food and the buses or trains to each trailhead. A few access roads and some parking areas in the Cortina and Tre Cime zone charge seasonal fees, but these do not affect through-hikers on foot. Joining the CAI or an alpine club affiliated through the reciprocal-rights system lowers hut prices and is worth it for a week-long trip.

Gear & Packing List

Because you sleep and eat in huts, you can travel relatively light — no tent, stove or full cook kit needed — but Dolomite weather swings fast, so layers and rain protection are non-negotiable. A pack in the 35–45 litre range is ideal. For a comfortable carrying system look at the Atmos AG 50 or the lighter Abisko Hike 35; ultralight hikers who keep their kit trim often prefer a frameless or roll-top pack such as the 2400 Windrider. If you want a deeper comparison, see our roundup of the best ultralight backpacks of 2026.

Essentials: sturdy B-rated hiking boots, a waterproof shell and warm mid-layer, hat and gloves (passes can be near freezing at dawn), trekking poles for the steep descents, a sleeping-bag liner for the huts, a 1–2 litre water capacity, sun protection, a basic first-aid kit and a headtorch. A via ferrata set is optional but useful if you add cabled variants in the Cristallo or Tofane. Keep food weight sensible — half-board covers most meals, so carry only trail snacks; if you are working out daily energy needs, our guide on how many calories you need hiking a full day is a good starting point.

Frequently Asked Questions

When is the best time to hike the Alta Via 9?
Early-to-mid September is the best window: the high passes are snow-free, summer thunderstorms have eased, hut crowds have thinned after the August holiday peak, and the larches start turning gold. The practical season runs from about 20 June to late September, matching when the manned rifugi are open along the route.

How difficult is the Alta Via 9?
It is a challenging multi-day route rated for fit, experienced mountain walkers. Most of the seven stages involve 1,000–1,500 m of ascent on rough paths, with exposed passes above 2,500 m and occasional cabled sections. A head for heights and surefootedness on scree help, and early-season snow on the forcelle can add difficulty.

How long is each day on the trail?
The 140 km route splits into seven stages averaging around 20 km, but elevation matters more than distance. Expect 5 to 8 hours of walking per day with 1,000–1,500 m of climbing. Longer stages such as the Cortina and Sella sections (24–26 km) make for full days, so start early and pace for the steep descents.

Where do you sleep on the Alta Via 9?
You stay in manned mountain huts (rifugi) spaced roughly a day apart, including Rifugio Berti, Carducci, Fonda Savio, Son Forca, Pralongià and Friedrich August. Half-board with dinner and breakfast costs about €60–€80 per person; a dorm bed alone is €25–€35. Book ahead in July and August and bring a sleeping-bag liner.

Do you need a permit to hike the Alta Via 9?
No permit is required — the Alta Via 9 follows open public mountain paths through the Dolomites, and there is no fee to enter the UNESCO World Heritage area. Your main costs are hut half-board and the buses or trains to the trailheads. Joining an affiliated alpine club lowers hut rates over a week-long trip.
