A Paradise for Hikers and Nature Lovers

From seasoned trekkers to families looking for a gentle stroll, the Desert de Platé caters to all. The main sentier is a boucle de 1,7 km with a modest dénivelé positif that qualifies as difficulté facile for most randonneurs. For those craving a longer adventure, extensions lead to the refuge de Platé (2 700 m) and onward to the GR 96 that crosses the massif du Fiz.

Multiple Itineraries for Every Skill Level

  • Loop “Lunette”: 1,7 km, difficulté facile, perfect for families.
  • Plateau to Refuge: 5 km, moderate dénivelé positif, sentier modéré.
  • Full Alpine Traverse: 12 km, difficulté difficile, suitable for experienced mountaineers.

All routes are clearly marked with panneaux orange and are included in the sentier géologique maps that highlight the numerous fossiles and gouffres along the way. If you’re interested in a more immersive experience, consider hiring an accompagnement guide – many local guides specialize in karstic terrain and can point out hidden canyons and the ancient marine fossils that lie scattered across the vista.

Spectacular Limestone Plateau and Lapiaz d’Europe

The Desert de Platé is essentially a gigantic plateau calcaire shaped by erosion over millennia. The result is a maze of fissures, “pleines galeries”, and towering rock formations that give the area its lunaire character. Walking across these stone corridors feels like stepping onto another planet – a sensation often described as “désert lunaire” by visitors.

Geologists explain that the lapiaz d’Europe is the product of water percolating through the porous limestone, creating a network of underground rivers that later collapse to form the spectacular surface pattern we see today. The most iconic spot is the “glacier pétrifié”, a frozen river of stone that glistens under the sun, providing a perfect backdrop for photographers.

Highlights of the Karstic Landscape

  • Gouffres et canyons – natural pits up to 30 m deep.
  • Plateau d’Assy – a quieter side‑track offering sunrise views.
  • Roches lunaires – bright white limestone that reflects moonlight even in daylight.

Because the environment is fragile, the site classé authorities request visitors to stay on designated walkways and avoid touching the delicate rock formations. A few well‑placed passerelles help protect the most vulnerable zones while still offering spectacular viewpoints.

Wildlife: Marmots, Bouquetins and Alpine Flora

The Desert de Platé is not a barren desert in the ecological sense. Its high zone d’altitude nurtures a surprising faune et flore. Early mornings often reveal curious marmottes perched on rocks, while the occasional bouquetin silently surveys the landscape from a ridge.

Botanists note that despite the stark appearance, the plateau supports a rich flore alpine including Edelweiss, Gentiana and rare alpine grasses that turn golden in late summer. The surrounding woods host faune alpine such as chamois, red foxes, and a variety of bird species, making the area a paradise for wildlife photographers.

Conservation Efforts

Local conservation groups, supported by the conservateur du parc naturel, run regular clean‑up campaigns to tackle litter left by tourists. Visitor responsibility is crucial; leaving plastic or food waste can disturb the delicate balance and scare away the shy marmottes. The area’s designation as a site naturel protégé ensures that any development is carefully assessed to preserve the unique ecosystem.

Practical Information: How to Plan Your Visit

Getting to the Desert de Platé is straightforward. From Flaine, take the téléphérique des Grandes Platières which runs year‑round, with a slightly higher price in the summer. The lift drops you at the plateau’s edge, where a short walk leads to the main trailhead. If you prefer to hike, the GR 96 can be accessed from Passy or Sixt‑Fer‑à‑Cheval – both starting points are well‑signposted.

When to Go

  • Saison d’été (June‑September): Ideal for hiking, wildlife spotting, and photography. Temperatures range from 5 °C to 15 °C.
  • Saison d’hiver (December‑March): Snow‑covered trails become a quiet haven for winter walkers; the glacier pétrifié glistens under a blanket of white.

Whether you’re planning a day trip or a multi‑day trek, remember to planifiez votre visite around weather forecasts. The plateau’s altitude means weather can shift rapidly – sunshine one moment, a sudden snowstorm the next.
