It was once a royal hunting reserve for the sovereign family; today it stands as one of the most extraordinary places in the entire Alpine arc for those who love mountain scenery, wildlife, and ambitious treks. It is the Gran Paradiso National Park, the oldest in Italy, established on December 3, 1922. A unique corner of Italy offering vast panoramas of some of the most dramatic peaks in the Alps, a sky of incomparable blue, and a dense and varied network of trails suitable for every hiker.
Summer is by far the most generous season for visiting Gran Paradiso, with green pastures at high altitudes, dotted with blossoms. The trails are accessible in their full extent, without major natural obstacles. It’s not necessary to be an experienced climber: the Park welcomes anyone who wishes to immerse themselves in its unique natural setting, and perhaps be lucky enough to spot some of the splendid wildlife characteristic of the Alpine fauna: ibexes, marmots, and chamois.
Where is Gran Paradiso National Park Located
Gran Paradiso National Park lies straddling two regions: the Aosta Valley (which covers just over half) and Piedmont. With an area of more than 70,000 hectares spread across thirteen municipalities, it is one of the largest and best-preserved alpine parks in Europe.
On the French side it borders the Vanoise National Park, forming a transboundary protected area of about 120,000 hectares: one of the continent’s most important natural sanctuaries.
The territory develops around the Gran Paradiso massif in the Graian Alps, divided into five main valleys: on the Aosta Valley side are the Val di Cogne, Valsavarenche, and Val di Rhêmes; on the Piedmont side the Orco Valley and the Val Soana. Elevations range from 800 meters in the valley bottoms to 4,061 meters at the Gran Paradiso peak, the only 4,000-meter summit entirely within Italian territory.
Dominating the high-altitude landscape are the 59 glaciers that characterize the Park, with the largest extents on the valley side in Valle d’Aosta. The line of perpetual snow sits around 3,000 meters, while below that altitude the mountains are cloaked in stands of larches, red firs, and Swiss stone pines. The flora of the alpine meadows is speckled with Gentians, alpine poppies, and rhododendrons.
What to Do in Summer in the Gran Paradiso National Park
Summer is the ideal time to explore the Gran Paradiso. With clear weather and snow-free trails, the Park’s intricate web of paths becomes the main lure for anyone passionate about alpine trekking.
As you walk along the numerous routes, it is quite common to encounter the park’s typical wildlife, since it hosts one of Europe’s most substantial ibex populations: estimates place them between 2,500 and 3,500 individuals. Chamois and marmots are equally plentiful, making it rare to traverse any path without hearing their distinctive whistles or catching sight of them perched on guarding rocks near their dens.
Apart from hiking, the park offers ample opportunities for bike touring on routes that are both paved and gravel, suitable for various levels of fitness.
An essential family stop is the Paradisia Alpine Botanical Garden, located in Valnontey, in the Cogne Valley, at an altitude of 1,700 meters. Founded in 1955, it hosts over 1,500 species of local and introduced plants; the peak flowering period occurs between June and July, when the garden becomes a festival of colors and fragrances.
Three Hikes Not to Miss in Gran Paradiso National Park
As mentioned, the main activity within Gran Paradiso National Park is trekking. Especially on the Val d’Aosta side, the protected area functions much like a university for alpine hiking: although there are routes suitable for all fitness levels, many itineraries include demanding ascents that push to high elevations, where the air thins, the sky becomes bluer, and the views gained during the climb and at the summit become increasingly precious.
From Valnontey to the Vittorio Sella Shelter
One of the park’s classics. The hike starts from Valnontey in the Val di Cogne at about 1,700 meters, and climbs the valley to the Vittorio Sella Refuge (2,584 meters), following a well-marked path that traverses first through stands of larches and then opens onto wide, spectacular high-altitude meadows.
The overall distance is about 8 kilometers with a positive elevation gain of around 900 meters, and an ascent time of roughly three hours. It is a tough trek, but not impossible: with a bit of preparation, it is approachable for many hikers.
What makes this excursion special is first and foremost the scenery, with views toward the glaciers at the head of the valley. The chances of encountering ibex, marmots, and chamois are fairly high, especially near the Lauson Lake, a small yet captivating body of water not far from the refuge, nestled in a dramatic setting with several glaciers visible all around and typically a blossoming of gentians, violets, and primroses along its shores.
From the Piano del Nivolet to Lake Rosset
Accessible on foot or via the Park’s free shuttles, the Piano del Nivolet stands as one of the most captivating high-altitude plateaus in this corner of the Alps. It stretches for more than six kilometers, at an altitude of around 2,500 meters, in the heart of the park’s Piedmont side along the Orco Valley.
The environment is typical of high-altitude regions: alpine lakes fed by small snowfields and glaciers, the swift Dora del Nivolet stream, marshy meadows where species adapted to extreme habitats flourish. A panoramic traverse lets you cross the entire plateau with a continuous balcony overlooking the Orco Valley: an itinerary suitable for hikers with little experience, featuring modest elevations and exceptionally beautiful viewpoints.
For those who crave more than a flat stroll, there is a short ascent to Lake Rosset, about 500 meters higher, following a challenging trail of just over two kilometers. You arrive at a special, more secluded spot, another balcony offering a privileged view of the surrounding peaks, with a small, charming body of water at its center.
More experienced hikers can continue for another three kilometers to reach Col Rosset, where the border between Piedmont and the Aosta Valley passes, at an altitude of 3,023 meters.
The Lillaz Waterfalls
For those seeking an accessible hike suitable even for children, the Lillaz Waterfalls loop in the Val di Cogne is the ideal itinerary.
Starting from the small village of Lillaz, a few kilometers from Cogne, one follows a path that climbs along the Urtier stream, accompanied by the roar of water tumbling down in spectacular steps for a total drop of over 150 meters.
The route is short, about 4 kilometers in a circular loop, and suitable for all. From the car park it takes barely ten minutes to reach the lower cascade, after which a climb begins that quickly leads to the other two beautiful drops along the stream. The natural surroundings are truly unique, and the cold waters of the stream help cool the air on hot summer days, providing a refreshing relief when temperatures rise.
