The Mercantour is France's most biodiverse national park — a place where Alpine and Mediterranean ecosystems collide in one of the steepest environmental gradients in Europe. Within 50 km, you can travel from olive groves at 500 m to glacial lakes at 3,000 m. This is where wolves returned to France in 1992, where 40,000 Bronze Age rock engravings cover a sacred mountain, and where you can swim in the Mediterranean and hike through snow on the same day.

Geography
The Mercantour sits in the Alpes-Maritimes and Alpes-de-Haute-Provence — the extreme southeastern corner of France, bordering Italy (linked with Italy's Parco Naturale Alpi Marittime). The landscape is extraordinary:
- Deep, steep-sided valleys radiating from the Italian border
- Lakes of glacial origin at altitude (over 60 Alpine lakes)
- Mediterranean vegetation on south-facing slopes at low elevation
- Alpine tundra and snowfields above 2,500 m
The Vallée des Merveilles
The Vallée des Merveilles (Valley of Wonders) is the park's most extraordinary feature — a high-altitude valley (2,100–2,700 m) at the foot of Mont Bégo, where over 40,000 Bronze Age rock engravings cover glacially polished orange rock. The carvings — dating from 3,300–1,800 BCE — depict cattle, weapons, geometric patterns, and human figures. Access is by foot (2–3 hour hike) or with authorised park guides.
Wildlife
The Mercantour's biodiversity is exceptional:
- Grey wolf: This is where wolves returned to France in 1992. Multiple packs now resident.
- Ibex: Reintroduced from the Italian side — growing population
- Chamois: Several thousand
- Mouflon: Introduced (Corsican origin)
- Golden eagle, short-toed eagle, eagle owl: Raptors benefit from the extreme terrain
- Hermann's tortoise (at lower elevations)
- Italian wall lizard, Corsican fire salamander: Mediterranean and endemic species
Botanical highlights include Europe's northernmost olive trees alongside Arctic-Alpine plants — gentians, saxifrages, and the rare Saxifraga florulenta (endemic to the Maritime Alps).
Hiking
- GR5/GR52: Both long-distance trails pass through the park
- GR52A (Panoramique du Mercantour): A spectacular 10-day traverse
- Day hikes: Lac d'Allos (Europe's largest natural high-altitude lake at 2,228 m), Vallée des Merveilles, Gorges de Daluis (red rock canyon)
- Difficulty: Trails are often steep and rocky — the mountain terrain is more rugged than the Vanoise
Nice — Nice is the gateway to the Mercantour — 90 minutes from the coast to the park entrance — on La Porte.

The useful unit is one place or one question, not a fourteen-day montage of France. Mercantour National Park sits in a country that is easy to over-plan and easy to under-prepare. The parks layer is where visitors collect names. This page is the opposite: what to do first, what to skip, and which sibling guide holds the rest.
France rewards a slow unit. One arrondissement, one valley, one appellation, one park trail. The photograph of five landmarks in five days is a real holiday, and it is also a queue with a passport. If you only have three nights, spend two of them in the same bed. The third night is for a train, not a third hotel.
Working a visit
Practical France is sockets (Type E/F, 230 V), tap water that is safe, pharmacies that are the real clinic for minor trouble, and a lunch hour that still closes a village. Cards work in cities. Cash still opens some park kiosks, some island boats, and some market stalls that have never seen contactless. A lightweight adapter belongs in the personal item, not the hold.
We will not write as if every reader is on a gap year, or as if every reader is in a palace hotel. We will not flatten 'the south' into one climate. We will not treat a strike day, a jour férié, or a Tuesday museum closure as a personality quirk of the French. They are calendars. Check them. Then use Mercantour National Park as a pin, not as scripture.
Cross the five guides instead of cloning them. La Porte holds trains and the first week. La Terre holds weather and park gates. L'Esprit holds museum Tuesdays and the Revolution. La Table holds the market morning and the wine list. Le Moteur holds the Tour, the working week, and why August is empty in Paris and full on the coast.
