Val di Fumo

Although not everyone knows it as it deserves, this place should be visited at least once in a lifetime, because Val di Fumo it is one of the most beautiful places in western Trentino.

We're talking about a valley of glacial origin, located within the Adamello Brenta Natural Park, the starting point for adventurous excursions in the Adamello mountain range, often undertaken to fully experience nature, but also to encounter the relics of the Great War preserved along the high-altitude trails.

Features

As soon as you enter Val di Fumo, it is as if you felt nature remaining still and at the same time running towards you: you immediately hear the musical sound of flowing water, the wind that insinuates itself through the leaves of the trees and the scents of the earth to breathe deeply.

From the artificial lake of Malga Bissina to the meadows crossed by the Chiese, the water constantly changes its appearance. First it fills the large basin at the foot of the dam, then flows freely back into the stream, splitting into several branches and curving through wetlands and pastures. Toward the head of the stream, the view takes in the Carè Alto and the other peaks of the Adamello, while on the valley sides, pale rocks, hollows, and glacial deposits emerge.

As you walk, you can clearly see the valley's U-shape, which extends from north to south for almost eleven kilometers. Roches moutonnées, striations, moraines, and depressions testify to the passage of ancient glaciations; the smooth profile of the valley floor contrasts with the jagged slopes, making the landscape appear vast even when the trail stays close to the river.

Water, woods and large prairies have fueled the nickname of Little Canada of Trentino, a suggestive comparison that does not, however, exhaust the identity of the place. Even the origin of the name Val di Fumo remains uncertain: according to the two hypotheses reported by the Park, it could derive from the Latin finish, that is, border, or from the smoke of fires practiced in the past to create new pastures.

The hike from the dam to the Val di Fumo refuge

The excursion begins at the Malga Bissina dam, at the end of the road that climbs the Val di Daone. After leaving the car, continue on foot along the western shore of the lake: the lake lies to the right, the valley walls begin to narrow the view, and, looking back, the dam is clearly visible.

Between large meadows, small bridges, mountain huts, and grazing animals, the elevation gain is modest, but the distance to the refuge is significant and must be factored in along with the return journey. It's this elevation gain, more than the elevation gain, that determines the day's effort.

After about three kilometers you reach Breguzzo Alpine Pasture, a useful stopover for those seeking a shorter walk. Shortly thereafter, the long stretch beside the lake ends, and the valley opens onto meadows crossed by the branches of the Chiese River. In some places, the route can be split on both sides of the river, but it shouldn't be assumed that it's a 100% passable loop: the ground, water, and seasonal conditions vary. It's best to follow the signage and choose a route appropriate for the day's conditions.

The next stop is Fumo Valley Mountain Hut, located in the valley basin. From here the SAT 240 trail tackles the short final climb towards the Val di Fumo refuge, located higher up and therefore distinct from the mountain hut. This difference is important both for orientation and for planning a stop: reaching the mountain hut doesn't mean you've already reached the refuge.

For the classic route, the Park documentation indicates approximately 150 meters in altitude and 7 kilometers each way; Official route sheet between the dam and the refuge allows you to check the path, while the SAT reports 1 hour and 30 From Malga Bissina Lake, follow the road that runs along the basin and trail 240. The hour and a half is just the walk to the refuge: photos, lunch, landscape viewing, waiting, and the pace of the group can add a significant amount of time to the day. Once there, you also have to walk back through the same valley.

The moderate gradient makes the hike less strenuous than many Alpine hikes with steep elevation gain, but it doesn't automatically make it a short itinerary or one suitable for everyone. The distance is especially important on the return journey; on the open sections, you can walk for long periods in the sun, while rain and humidity can affect the surface. Added to this is the starting altitude, which still requires mountain clothing and plenty of room for rapid changes in the weather.

Before setting out, choose a destination that's compatible with distance, weather, and the group's ability. The lake and dam offer a quick visit; Malga Breguzzo offers a recognizable intermediate destination; Malga Val di Fumo and the refuge require planning the entire outward and return distance. If your pace slows, the weather changes, or your stops have been longer than expected, you can turn around before the refuge.

Shoes with suitable soles, water, sun protection, and a layer for wind or rain are essential, even on days that start out clear. In the upper Daone Valley and in the Fumo Valley, cell phone coverage is not guaranteed: schedules, contact information, reservations, and other necessary information should be saved before climbing.

Alpine pastures and refuges: three different stages

Breguzzo Alpine Pasture, Fumo Valley Mountain Hut e Val di Fumo refuge There are three distinct stages. The first is still along the lake and can be the end point of a shorter hike; the second is located in the open valley floor, next to the Chiese; the refuge, on the other hand, occupies a raised position above the basin and requires the final stretch of climbing.

The refuge offers food and overnight accommodation during the summer season, but opening times, availability and actual services should be checked directly before departure, especially if lunch is an essential part of the program or you intend to spend the night at high altitude. Official information sheet for the Val di Fumo Refuge Gather useful contacts. Bringing your own water supply and something to eat prevents your day from being entirely dependent on seasonal service.

From the refuge, the view returns to the lake and the Daone Valley to the south, while to the north it follows the Chiese River, the basin, and the glacial formations of the upper valley. The classic hike ends here; the trails that continue require a completely different assessment.

What to do in Val di Fumo with children

With children, you can plan intermediate stops: the dam and lake, Malga Breguzzo, or a refuge. Along the shore, you can observe the transition from the reservoir to the meadows, the water, the small bridges, and the grazing animals, keeping a safe distance. Malga Breguzzo, after about three kilometers, allows you to finish the hike without tackling the entire route.

To continue to the refuge, the key factors are walking habits, the child's independence, the heat, the terrain, and the time left to return. There's no one-size-fits-all age. Those accustomed to hiking can reach the refuge; others can finish the hike along the lake or in the open valley. It's a good idea to agree on a possible intermediate destination beforehand and conserve energy for the return journey, when the initial enthusiasm and distractions wane.

The official route sheet indicates that the complete itinerary It is not suitable for strollersThe small elevation gain doesn't necessarily reflect the smoothness of the terrain or all the sections of the hike. With small children, it's best to choose a destination within walking distance or use age-appropriate support, also considering the weight they'll need to carry for the entire return journey.

In the nearby Val di Daone there is also A trail for everyone in Nudole, a distinct trail of about a kilometer and with no elevation gain, suitable for those seeking a very short walk, even with a stroller. Nudole is not a variant of the Val di Fumo: the starting point, the setting, and the visit are different.

How to get to Val di Fumo

To reach the Val di Fumo, you must ascend the Val di Daone to the Malga Bissina dam. From Trento, the usual access route passes through Sarche and Tione di Trento, then continues towards Daone and along provincial road 27. The final stretch climbs through the valley with hairpin bends and requires a different time than suggested by the road distance alone.

Malga Boazzo Lake is located further down the road, while the trail to Val di Fumo begins at Malga Bissina. Once you reach the dam area, park your car and continue on foot along the western shore of the lake.

In summer, access should not be organised by relying only on the navigator. For the 2026 The Park publishes a timetable for managing the rest areas and, on the days indicated, a presence from 8am to 18pm. The timetable, conditions and any changes are reported on the official page dedicated to parking and mobility in Val di Daone and Val di Fumo.

For Malga Bissina, the Park recommends purchasing parking online by 6:00 a.m. the same day. On-site purchases are still possible only if spaces are available. When the Malga Bissina area fills up, vehicles are directed first to the ENEL parking lot at the base of the dam and then to the areas further downstream; parking below Nudole remains free.

Coming from Campiglio, however, you will have to drive along the SS239 to Tione, continue on the SS237 to Daone and then continue on the SP27 to the Malga Bissina car park.

You can't rely on generic, direct, and frequent buses from Trento or Campiglio throughout the season. In the 2026 system, internal shuttles between Pracul and Bissina are free and cannot be booked; timetables, stops, and service periods should be checked on the website. summer mobility pageThose arriving without a car should check all outbound and return connections for the exact day, taking into account the waiting time and the last available service.

Campers, tents and park rules

Near the Malga Bissina dam acamper parking area There's a fee, open in the summer when road conditions allow, and equipped with water loading and unloading points. Opening times, road conditions, fares, and availability should be checked before boarding.

The presence of a camper area does not automatically allow you to pitch a tent or spend the night outside of the authorized spaces. Those wishing to spend the night at the refuge may park their car only according to the parking conditions; for a night in a tent or a bivouac, you must contact the Park directly for confirmation, specifying the date, location, and conditions.

In Adamello Brenta Natural Park Waste must be returned to the valley, natural elements must not be removed, and equipment must be adapted to rapidly changing weather conditions. In the Daone Valley, dogs must be kept on a leash where required; before planning a stop or overnight stay, it's also important to check the shelter's accommodation policies.

Photographing the Val di Fumo

The Fumo Valley offers a variety of views along the entire hike, so focusing on a single vantage point reduces the narrative of the place. At the starting point, the focus is on the relationship between the dam wall, the lake, and the mountains. Along the western shore, the water, the banks, and the progressive opening of the valley come into the frame; beyond Malga Breguzzo, the branches of the Chiese River, the meadows, the mountain huts, and the U-shaped profile carved out by the glacier become central.

The return journey isn't a simple repetition: proceeding south, the valley, the lake, and the Val di Daone are reassembled in the same view. Even with less spectacular lighting, this inversion of perspective allows for a more complete series. Water and wetlands require careful attention to reflections and the sky, while grazing animals can only enter the landscape by maintaining a distance and without influencing their behavior.

In summer, the Val di Fumo attracts many visitors, but their numbers vary depending on the day, time of day, and the route traveled: the parking lot and the lake shore concentrate different flows than the valley floor. Starting with a good head start helps manage parking, stops, and the return journey, but this doesn't guarantee you'll have the landscape to yourself.

A day dedicated to photography requires a much longer time than the 30 hours indicated by the SAT for just accessing the refuge, as you need to add the waits for light, rest stops, and the return journey. If you plan to stay late, travel times, weather, and return journeys should be planned before entering the valley, especially since your cell phone signal may be limited.

The dam, the glaciers and the traces of the Great War

Malga Bissina Lake now seems like a natural part of the valley's entrance, but it was born from a recent transformation. The dam was built between May 1955 and November 1957 and tested in 1962. The concrete barrier is 563 meters long and 81 meters high. Starting from here, therefore, means first crossing a man-made landscape and then entering, step by step, into the upper valley shaped by water and ice.

Further ahead, the glacier's work is visible in the U-shaped section, the rounded and marked rocks, the moraines, and the humid basins. The Chiese collects the Adamello's meltwater and distributes it along the valley floor, forming branches and meanders. This geography helps explain why water is so present in the perception of the Val di Fumo and why its sound accompanies the journey far beyond the lake.

The mountains around the valley also preserve evidence of the Great WarThe high-altitude connections to Passo delle Vacche and Passo San Valentino pass through areas affected by the conflict on the Adamello. However, these are not short detours to add to the hike to the refuge: they are part of more challenging itineraries, requiring independent planning.

Where the classic excursion ends

The Val di Fumo refuge is the end point of the classic hike, and from there you return to Malga Bissina. The continuation routes to the Carè Alto refuge and the Lissone refuge are classified as suitable for experienced hikers; the crossing to the Ai Caduti dell'Adamello refuge requires mountaineering skills. Distance, exposure, orientation, and terrain are significantly different from the route along the lake and the Chiese river.

Beyond the Val di Fumo Refuge, the terrain, difficulty, and duration change. Those intending to continue should plan their own itinerary, check the conditions and opening times of the refuges, and have the required experience: the expansive landscape and modest elevation gain at the valley floor do not predict the difficulty of the upper routes.

Already at the lake, you can see the dam and the entrance to the valley; Malga Breguzzo shows the transition from the reservoir to a more open landscape, while continuing to Chiese leads to the most recognizable part of the valley floor. These are points where you can end the hike if the weather is uncertain, the group has different paces, or the available time doesn't allow for a comfortable return.

Further down, in the Val di Daone, the Nudole trail offers a separate, much shorter hike with no elevation gain. It can be a practical option if you're traveling with a stroller, have limited time, or the weather isn't suitable for the entire hike to the Val di Fumo.

Before setting out, it's a good idea to check four things that may change: parking availability and mobility in 2026, refuge opening hours, forecasts at the altitude, and your group's condition. By setting out with enough headway, you can listen to the water and observe the shape of the valley without rushing your return.

Where to stay to visit Val di Fumo

Sleeping in Daone or in one of the other fractions of Valdaone We stay along the road that goes up the Val di Daone towards Malga Bissina. Those who prefer to stay further down the valley can look for accommodation in Pieve di Bono-Prezzo or in the other villages of the Valle del Chiese, but taking into account going up the valley on the day of the excursion. official portal Where to sleep It allows you to search for local facilities and contact them directly; availability and services must be verified for the selected dates.

Il Val di Fumo refuge It allows you to stay overnight in the upper valley, but can be reached on foot along the route described and does not replace a base accessible by car. It's an option for those who want to spend the night at altitude and return to Malga Bissina the following day; opening times and availability must be confirmed and booked directly with the manager.
