Alta Via 1 of the Dolomites
Trekking in July and September
Alta Via 1 is the most well-known long-distance trek in the Dolomites. It is a continuous, multi-day journey through some of the most iconic mountain groups of the range, linking alpine huts, valleys, and very different environments along the way.
Over the years I have walked long sections of Alta Via 1 in different seasons and with people who had very different expectations. For this reason, I know how much the time of year you choose can shape the overall experience. July and September are both excellent months to walk Alta Via 1, but they offer noticeably different conditions and atmospheres.
On this page you will find a clear, practical guide to Alta Via 1, based on first-hand experience and aimed at helping you choose the most suitable period for your trek.
What is Alta Via 1 of the Dolomites
Alta Via 1 is a long-distance hiking route that crosses the Dolomites from north to south. In its classic form, it connects a series of alpine huts via well-marked hiking trails; over time, several variants and partial itineraries have also developed.
General characteristics:
- linear, multi-day itinerary
- overnight stays in mountain huts, with hotel accommodation only on arrival in Cortina and at the end of the trek
- well-marked hiking trails, with no technical mountaineering sections
- very varied scenery: forests, high plateaus, limestone walls, passes and saddles
Alta Via 1 is often considered the most classic of the Dolomites’ high routes and is walked entirely on well-marked hiking trails. While it does not involve technical mountaineering, it remains a physically demanding trek that requires good preparation and the ability to walk for several consecutive days.
Alta Via 1 trail marking
The official symbol of Alta Via 1 is a triangular trail marker, most commonly blue.
The Dolomites’ Alte Vie follow hiking paths marked with a triangle with a white interior, showing the route number.
The triangle colour may vary slightly depending on the area or the age of the signage, but the shape and number remain consistent along the route.
Who Alta Via 1 is suitable for
Alta Via 1 is suitable for:
- hikers with some prior mountain experience
- people used to walking several days in a row
- those looking for a first long-distance trekking experience in the Dolomites.
It is not recommended for:
- those with no previous hiking experience
- people who struggle significantly with exposure or sustained elevation gain and loss
- anyone who underestimates the cumulative effort of walking day after day.
From a technical point of view, there are no mountaineering difficulties, but the overall length of the route and the succession of stages make the real difference.
For clarity: the July and September trekking options mentioned below are organized by cortinadampezzo.it, with whom I collaborate directly. My role here is to provide context and help you understand the differences between the itineraries.
Accommodation and pack weight on Alta Via 1
One of the reassuring aspects of walking Alta Via 1 is that there is no need to carry a heavy backpack. The route is designed around overnight stays in well-equipped mountain huts, which offer a surprisingly high level of comfort given their location.
The huts along Alta Via 1 provide proper meals, sleeping facilities in dormitories or small shared rooms (usually with two to four beds), hot showers and basic services.
In many ways, they function like mountain hotels, naturally with the practical limitations that come with being at altitude. This organization allows hikers to travel lighter, focusing on the walking itself rather than on carrying unnecessary equipment. You are not expected to be self-sufficient for multiple days, nor to carry food supplies beyond what is needed during the day.
Of course, this is still a high-mountain environment, and comfort should be understood in context — this is not the place to expect luxury extras — but the overall level of organization makes Alta Via 1 accessible to well-prepared hikers without the burden of a full expedition-style pack.
Alta Via 1 in July
July is the period when Alta Via 1 is walked in conditions closest to its classic high-summer setting. Days are long, there is more daylight available, and the overall pace reflects the busier conditions typical of high summer in the Dolomites.
The July itinerary follows a route inspired by the classic Alta Via 1, including some of its most representative sections and preserving a strong sense of continuity from one stage to the next.
Main features:
- longer duration compared to September
- more extended itinerary, including the Rifugio Tissi stage
- overnight stay in a 4-star hotel in Cortina on arrival and at the end of the trek
- long daylight hours for walking
- generally higher trail traffic, especially on well-known sections.
July is not the quietest period, but it is the one that delivers Alta Via 1 at its most complete in terms of atmosphere: lively huts, frequent encounters on the trail, and a strong sense of an ongoing journey from start to finish.
It is the right choice for those who want to experience Alta Via 1 with one additional day of walking compared to the September option, and who are comfortable sharing the trail with other hikers.
For those interested in this version of the trek, a July Alta Via 1 itinerary is available. Compared to September, it follows a more extended route and includes one additional day of walking.
Alta Via 1 in September
September is a very popular month for walking Alta Via 1, especially for those looking for a slightly different rhythm compared to peak summer. Trails and huts remain active and frequented, but visitor presence is generally more evenly spread and less concentrated.
The September itinerary follows much of the July route, with a few variations designed to adapt the overall length and rhythm to the season, particularly in the final stages.
Main features:
- one day less of walking compared to July
- final variant from Passo Staulanza to Malga Ciauta, without the Rifugio Tissi stage
- overnight stay in a 3-star hotel in Cortina on arrival and at the end of the trek
- temperatures often ideal for hiking
- trail traffic generally lower than in July, but still present.
September does not mean solitude, but rather a steadier and less hectic rhythm. Days are shorter, but the overall quality of the trekking experience remains high, with a more composed and reflective atmosphere.
This option is particularly suitable for those with limited time available, or for hikers who prefer a slightly shorter Alta Via 1 while still experiencing a coherent, well-structured journey along the route.
A September Alta Via 1 itinerary is also available. Compared to July, it includes one fewer day of walking while maintaining a coherent and well-balanced journey along the route.
Differences between July and September on Alta Via 1
The differences between July and September are not limited to itinerary length. They also involve light, weather patterns, landscape details and overall feel, all of which influence the experience.
July
- generally warmer temperatures, though never excessive at altitude
- flowering meadows and richer alpine flora
- a distinctly summer atmosphere, with lively mountain huts
- higher likelihood of afternoon thunderstorms compared to September
July is the month of colour and energy: the mountains are at the height of the season, and the trek is accompanied by a strong sense of vitality.
September
- clearer air and often excellent visibility
- lower sun angle and longer shadows, which make rock faces and mountain structures easier to read
- generally more stable weather conditions
- higher chances of spotting chamois early in the morning or at dusk
- particularly favourable light for experiencing the Enrosadira
September offers a more graphic and finely detailed mountain landscape, less explosive in colour but often more subtle and refined in atmosphere.
How to choose between July and September
Choosing between July and September is not about finding the “best” period in absolute terms, but about understanding what kind of experience you want on Alta Via 1.
Choose July if:
- you want to follow the itinerary in its more extended version
- you enjoy the lively atmosphere of peak season huts
- you appreciate flowering meadows and richer alpine flora
- you are comfortable sharing the trail with other hikers.
Choose September if:
- you prefer a slightly calmer pace
- you value clear air, angled light and long shadows on the mountains
