Everything you need to know about hiking the Alta Via 1 in the Dolomites
The Alta Via 1 is a stunning 125-kilometer trail that stretches from Lago di Braies to Belluno, traversing the heart of Italy’s Dolomites, a UNESCO World Heritage Site. Known for its awe-inspiring alpine landscapes, this iconic route offers about 7,300 meters of elevation gain, yet remains accessible to seasoned hikers, with well-marked paths and equipped sections where the terrain gets challenging.
The journey is best experienced as a hut-to-hut trek, where cozy mountain huts (rifugios) provide both refreshment and overnight stays along the way. Whether you’re an experienced trekker or planning your first multi-day hike, this guide has everything you need to prepare for an unforgettable adventure through one of Europe’s most breathtaking mountain ranges.
1. When to Hike the Alta Via 1
The best season for hiking the Alta Via 1 is from mid-July to mid-September. During this time, the trails are mostly clear of snow, and the rifugios (mountain huts) are open. The huts along the trail typically operate from mid-June to end of September, so this period offers the most flexibility and availability for accommodations. July and August are warmer but busier, while September is quieter yet cooler, especially at night and at higher elevations.
Snow Considerations
Even during the peak season, some snow may linger at higher elevations in early July. In these cases, carrying crampons or microspikes for better traction on snow-covered sections can be helpful. After mid-September, snowfall can return, especially at higher altitudes, so it's important to monitor the weather closely and come prepared for sudden changes in conditions.
2. Highlights of the Alta Via 1
The AV1 is packed with incredible scenery, but these three spots are the absolute standouts:
Lago di Braies (Pragser Wildsee): There is no better place to begin your journey than this iconic alpine lake. Famous for its emerald-green waters and the massive limestone cliffs that hug the shore, it provides a picture-perfect backdrop for your first steps on the trail.
Cinque Torri: Known as "The Five Towers," this unique rock formation is visually stunning and historically profound. It serves as an open-air WWI museum where you can walk through restored trenches and hideouts while admiring the jagged peaks.
Lagazuoi: Sitting high in the Ampezzo Dolomites, this area offers some of the most expansive panoramic views of the trek. It’s also famous for its history; you can explore the extensive wartime tunnels carved by Italian troops (bring a headtorch!) or simply enjoy the view from the terrace.
3. Accommodation: What Are Rifugios?
Rifugios are mountain huts where you’ll stay along the Alta Via 1. They offer far more than just a roof over your head - they range from comfortable to surprisingly luxurious, particularly in the first half of the hike.
Comfortable beds in shared dorms or private rooms.
Hot showers - some are free, while others require tokens.
Wi-Fi access are available in most huts, and some huts even have TVs.
Boot drying rooms and gear drying areas for wet clothing.
Some rifugios offer luxurious amenities like saunas to relax after a day’s hike.
Half-board options, which include a hearty dinner and all you can eat breakfast, ensuring you have the fuel you need for the next day’s hike.
As you progress further along the trail (south), however, the rifugios become more basic. The second half of the trek is more remote, and you may find yourself without Wi-Fi, with limited phone signals, and sometimes needing to share communal charging stations for phones and cameras.
4. How to Book Rifugios
Booking rifugios can be one of the more challenging aspects of planning your Alta Via 1 trek. Some rifugios have online booking platforms, while others require you to email or call them directly. To complicate matters further, each rifugio has its own booking schedule, with some accepting reservations as early as October and others not opening bookings until later in the spring.
Rifugios tend to get booked up very quickly, particularly in July and August, so it’s important to start planning well ahead. This can be stressful, as coordinating different booking methods and reservation times for each hut can feel like piecing together a puzzle.

5. What to Pack
Packing smart is crucial for a successful trek on the Alta Via 1. Weather conditions can change rapidly, and you’ll need to be ready for a variety of situations. Check out our hut to hut packing guide.
Here’s a list of essentials to bring:
Hiking boots: Sturdy, well-worn hiking boots with good ankle support are a must.
Waterproof layers: A high-quality rain jacket and pants are essential for sudden downpours.
Warm layers: Even in summer, temperatures can drop significantly at night or in higher elevations, so pack a fleece or down jacket.
Crampons or microspikes: These are useful in early or late season when snow might still be on the ground.
Hiking poles: These help reduce strain on your knees and aid in stability on rocky terrain.
Sunscreen, hat, and sunglasses: Protect yourself from the intense mountain sun.
Sleeping liner: Most rifugios provide blankets, but a liner adds comfort and cleanliness.
Towel and swimwear: Some rifugios are near alpine lakes where you can swim, so packing a lightweight towel is a good idea.
Snacks: While you’ll have meals at the rifugios, pack energy bars, nuts, and dried fruit for long days on the trail.
Water bottle or hydration system: Most huts have free at mountain water fountains outside the rifugios, which provide fresh spring water. However, some huts like Rifugio Biella do not have drinkable water.

6. How Long It Takes: Stats and Route Overview
The Alta Via 1 stretches for 125 kilometers and typically takes 8 to 12 days to complete. The hike starts at Lago di Braies and ends at La Pissa (Belluno).
Elevation Gain: Around 7,300 meters (23,950 feet).
Elevation Loss: Around 8,250 meters (27,067 feet).
The daily distances can vary between 10 to 15 kilometers, but the rugged terrain and steep ascents/descents mean it’s more challenging than a flat hike of the same distance. The highest point is Forcella Lagazuoi, which reaches over 2,752 meters (9,028 feet). Pacing yourself and being prepared for long days is key.
7. North to South or South to North?
While the Alta Via 1 can technically be walked in either direction, the traditional route is North to South (Lago di Braies to Belluno).
There are two main reasons for this:
Net Downhill: The finish line in the south is over 1,000m lower in altitude than the start (Lago di Braies), meaning you do slightly less climbing overall.
The "Warm Up" Factor: The southern section of the trail is generally more exposed and rugged. Walking North to South allows you to build your "trail legs" and adjust physically to the demands of the trek before hitting the most difficult terrain.
8. The Cost
Hiking the Alta Via 1 is relatively affordable compared to other European hiking routes, but costs can add up depending on your preferences. Budget for €60 to €130 per night for accommodation in rifugios, including half-board (dinner and breakfast).
Some rifugios charge extra for showers and other amenities, so it’s a good idea to bring some cash for these. Meals are generally hearty and filling, featuring local Italian specialties, which help fuel you for the next day’s hike.
While you can purchase drinks at the rifugios, water is available for free from mountain water fountains outside the huts, allowing you to refill your bottles along the way and stay hydrated without extra cost.
Most rifugios now accept card payments, but do carry some cash with you as some rifugios still only accept cash.
9. Dinning at the Huts
Rifugio food is a highlight of the Dolomites, so we highly recommend skipping the freeze-dried meals unless you are strictly budgeting. Here is how it works:
Half Board: This is the standard option at most huts. It includes your bed, a substantial breakfast (usually buffet style), and a 3-course dinner. Note: Some huts make half board mandatory.
A La Carte: If a hut doesn't offer half board, expect to pay around €20–€30 for a full dinner.
Lunch: You don't need to carry lunch either. You can buy a packed lunch from the hut in the morning or stop at one of the many rifugios along the trail for a midday break.
Our verdict: Pay the extra. Carrying days' worth of food adds unnecessary weight to your pack. There is nothing better than arriving tired and enjoying a warm, delicious Italian meal without lifting a finger.
10. Route Maps: Google Maps vs. Hiking Apps
While Google Maps can give you a general overview of the region, it doesn't have the specific hiking trails mapped out. For more accurate navigation, we recommend downloading apps like AllTrails, which offer detailed maps of the Alta Via 1, including elevation profiles and customizable routes. These apps also allow offline use, which is crucial given the limited cell service in the mountains.
Here’s a link to an interactive map on Google for general reference, but be sure to download detailed offline maps from AllTrails to navigate confidently. (Use my code: vivchow30 for 30% off AllTrials Plus to access features like off-line maps and GPS tracking)
11. Difficulty Level
The Alta Via 1 is classified as moderately difficult. While it doesn’t involve any technical climbing, the long distances, steep ascents, and rugged terrain can be physically demanding. Hikers should be in good physical condition, and previous experience with multi-day hiking is recommended. Adventurous hikers can find optional via ferrata routes along the way.
Some sections of the trail, particularly around steep passes, can be more challenging, but the well-marked paths and the availability of rifugios make it accessible for most hikers with a reasonable level of fitness. If you're new to multi-day treks, consider splitting some of the longer days or taking a rest day in one of the more comfortable rifugios.
12. Hiking with Pets
While you are welcome to bring your dog on the trails, finding accommodation is a different challenge. Not all rifugios allow pets to stay overnight.
Restrictions: Many huts strictly forbid animals.
Exceptions: Some huts may allow pets, but often only if you book a private room rather than a dormitory (i.e. Rifugio Coldai)
Fees: Be prepared to pay an additional cleaning fee at pet-friendly huts.
Email first: Because policies vary wildly, you must email each individual hut to inquire and confirm before you book. Never assume your pet will be accommodated without checking first.
Wildlife: On the trail, please remember to always keep your pets on a leash in order to protect the local wildlife - marmots, martens, and ermines call these mountains home!
13. Wild Camping
Wild camping is strictly prohibited in the Italian Dolomites, and mountain huts may give you a hefty fine if they find you wild camping nearby.
You do hear of AV1 trekkers who wild camp; the rule of wild camping generally means setting up late, leaving before sunrise, staying away from mountain huts, and being discrete. While we cannot condone the breaking of rules, if you do camp wild, you must adhere to strict Leave No Trace principles. Always take your rubbish with you and bury your toilet waste away from watercourses.
Final Thoughts
The Alta Via 1 is a spectacular hiking experience, offering a perfect blend of natural beauty, cultural immersion, and physical challenge. To make the most of your trip, be sure to book your rifugios early, pack wisely, and equip yourself with the right maps and tools for navigation.
