Do you long for a postcard setting where soft meadows lined with clear water stretch at the foot of an alpine lake, with horses, cows, and wild boars in the background? Welcome to the lake of Nino, a glacial pearl set in the heart of Corsica. At about 1,700 m altitude, this alpine character site unfolds its famous pozzine, green, spongy carpets that shine in the sun, while the GR20 grazes the horizon. The agenda: a sporty yet accessible hike, grand panoramas, fragile nature to respect, and a few smart tips to prepare this trip, from picturesque rail routes to Corsican villages. Head towards a natural treasure that deserves every step.
Discovering the lake of Nino: a natural treasure in Corsica
France is filled with preserved spaces, and Corsica stars with its mountains plunging into the sea. In the center of the island, straddling Haute-Corse and Corse-du-Sud, the lake of Nino unfolds a mountain scene worthy of a movie: a glacial basin of about 6.5 hectares, surrounded by a plateau bursting with green where streams wind. Here flows the Tavignano, Corsica’s second longest river: a discreet birth, a destiny of running water.
The site is savored like a reward: it is earned, it surprises, it soothes. And it is extremely photogenic: miniature water mirrors, lush grass, changing light, free-roaming animal silhouettes. A lively, almost pastoral setting, both fragile and fascinating.
An altitude jewel in the heart of the Corsican mountains
Perched around 1,740 m, the lake of Nino keeps the traces of its glacial past. Around, the pozzine — those marshy peat and grass meadows, dotted with water holes — act as natural sponges. You walk on a green cushion, listen to the water flow, observe the reflections dance with the wind. It’s unique in the Mediterranean, and of an almost unreal beauty.
At a bend in the stream, the scenery comes alive: horses, cows, and wild boars grazing, familiar with the place, add a touch of freedom to the landscape. All dominated by the granitic ridges, reminding that Corsica is a high, untamed, and splendid island.
A unique ecosystem
The pozzine serve as water lungs. They filter and retain water, nourish the flora, and shelter insects and amphibians. It’s the kingdom of moss, sedges, and micro-currents. One more reason to walk lightly, stay on paths, and preserve this fragile environment.
Access: hikes and alternatives outside the GR20
The GR20 grazes the lake on its route between Ciottulu di i Mori and Manganu, which explains the crowds in high season. But there’s no need to be on this mythical path to reach Nino. Two classic access points: from the col de Vergio or from the forest house of Popaghja.
Count on a day trip with about 700 m of elevation gain, sometimes steep sections, and a round trip of 6 to 8 hours for about fifteen kilometers. The pace adjusts to the altitude: you catch your breath, hydrate, admire. Note that there is no bivouac allowed by the lake; the tranquility of the pozzine cannot be improvised as a base camp.
On-site atmosphere
Arriving at Nino means being captivated by silence (when the seasons are a bit emptier) and by the gentleness of the meadows. The blue reflections on the raw green, the splashing of pools, the leisurely passage of a horse in semi-freedom… everything seems designed for contemplation. Photography enthusiasts will find the early morning hours magical, with guaranteed low light.
The GR20 in the background
Crossing the island from Calvi to Porto-Vecchio over about 180 km, the GR20 has an international reputation. Its uniqueness? A high mountain route, technical and sustained, requiring an average of 15 days of effort. Many choose to cover half of it: Vizzavona–Asco in the north, or Vizzavona–Bavella in the south.
In complete autonomy, it’s best to have a solid experience, excellent physical condition, and true navigation skills. The refuges can be fully booked in season, and the south → north direction facilitates the increase in difficulty. For more peace of mind, a local agency with a certified guide can manage the itinerary and part of the logistics.
When to go and how to avoid the crowd
The heart of summer is inevitably attractive. But to savor Nino at its best, target the shoulder seasons: late spring or very early autumn, when the grass is lush and the skies stable. In hot weather, leave early; in uncertain weather, give up — altitude can quickly change the situation.
A morning departure from the col de Vergio often offers peaceful trails, with golden light on the pozzine. Also consider weekdays for more tranquility.
Preparing your hike: safety and equipment
Identify your route and check access to the trails before you leave. Adjust the difficulty to your current fitness level. The weather? Check it the day before and on the morning of your hike.
Bring a detailed map and inform a close person of your itinerary. High-top hiking boots, warm and waterproof clothing are part of the kit, even under a hot island sun.
Plan at least 2 L of water per person and plenty of snacks. Add sun protection, a cap, sunglasses, small first aid kit, and strict management of your waste (take everything back down). Overnight stays in a refuge or gîte d’étape should be booked in advance.
Respect a fragile environment
The pozzine are not picnic lawns: walk on paths, avoid trampling spongy areas, leave no trace. Keep a respectful distance from free-roaming animals and do not feed them. The water of the pools, however clear it may be, is not a swimming area.
Coming without a car: travel ideas and rail breaks
To reach the Mediterranean ports before crossing to Corsica, the journey can start by train. Night trains offer a delightfully retro entry: sleeper, gentle pace, sunrise upon arrival. For inspiration, discover comfortable and picturesque night train routes.
Want to extend the rail break? Some spectacular European routes lead to Marseille, Toulon, or Nice, before a ferry to the island. A smoother way to approach the Corsican mountains.
Extend the escape: Corsican villages, lakes elsewhere, and culinary stops
After Nino, continue discovering Corsican villages with their blonde stone, shaded squares, and passionate artisans. This exploration of Corsica through its villages will give you ideas for characterful stops.
Thirsty for lakes? Head to the mainland for a poetic getaway along the enchanting lakes of Bourgogne, peaceful mirrors to glide between two island adventures.
And if your road passes through the Côte d’Azur, a stop in Cassis can beautifully conclude the journey. Here’s a selection of the best restaurants with a sea view: ideal to relive the Nino adventure against the waves.
Useful information for your adventure
To prepare your stay, consult the official destination website: www.visit-corsica.com. It compiles route ideas, accommodations, and practical advice on mountain conditions and local regulations.
One last word: watch for less crowded periods, leave early, keep a safety margin, and leave the site exactly as you found it. The lake of Nino will reward you a hundredfold, in beauty and memories.
