How to plan Alta Via 1: the complete step-by-step

Alta Via 1 runs about 120 km with roughly 6,800 m of ascent and 7,500 m of descent, topping out near 2,750 m. It is graded moderate: long days on your feet and some exposed, cable-aided sections, but no technical climbing. If you can walk 6 to 8 hours a day on steep ground for a week, you can walk Alta Via 1.

The route is one-way, north to south, starting at Lago di Braies and finishing above Belluno. That direction matters for planning: it decides how you get in and out, and it is the direction almost every hut and bus timetable assumes.

The classic itinerary is 11 days hut to hut, but strong walkers combine stages into 9, and there are shorter versions that exit partway. More days means shorter, easier stages and more time for the side trips; fewer days means some long, demanding days back to back.

The honest way to decide is to build the exact night-by-night plan and look at the hours per day, rather than picking a number first. The planner on this site does exactly that: set Lago di Braies and Belluno as your start and finish, and it splits the route into days within the daily walking hours you are comfortable with, so a demanding 9-day version and a gentle 11-day version are both one setting apart.

The season runs mid-June to late September. Late June still carries snow on the high passes in a heavy winter; July and August are warm and busy and the huts are fully staffed; September is quieter and clearer but the huts start closing from mid-month and the last ones shut around the end of September.

For the trade-offs month by month, see the best time to hike the Dolomites guide and, if you are drawn to the quiet shoulder, the Dolomites in September.

This is the step that makes or breaks the trip. Alta Via 1 sleeps in rifugi that fill months ahead: the popular ones (Lagazuoi, Nuvolau, Coldai) book out within about two weeks of their calendars opening in March. Lock your dates and route first, then email all the huts as one coherent plan.

The full sequence, including an Italian email template and what to do when a hut never replies, is in how to book Dolomites huts and when to book Dolomites huts. If you are not sure the budget works, what Dolomites hut-to-hut costs breaks down a realistic week, and is CAI membership worth it explains the roughly 30% half-board discount that pays for itself over a few nights.

The start and finish are at opposite ends of the range, so the logistics are a real part of the plan. Most walkers fly into Venice or Innsbruck, reach the northern trailhead at Lago di Braies by train and bus, and return from Belluno at the southern end.

The access routes, airports and the summer bus booking for Lago di Braies are covered in getting to the Dolomites and the closest airport to the Dolomites.

Alta Via 1 is walkable by any regular hiker, but back-to-back long descents are what catch people out, so train the downhill, not just the climbs. Huts provide blankets and half board, which keeps the pack light: no tent, no stove, no sleeping bag, just a liner.

See training for a Dolomites hut-to-hut and the hut-to-hut packing list for the specifics, and rifugio etiquette so the first night in a shared dormitory holds no surprises.

Once the window and the day count are settled, turn them into a concrete itinerary: one named hut per night, with the walking hours and the ascent for each day, in the order you will actually book them.

Open the Alta Via 1 route on the planner to load the whole traverse, then adjust the pace and the stops to your group and export a plan you can email to the huts. For the route in guidebook form, with the character of each stage, see the Alta Via 1 route page.
