  Geology

  A landscape sculpted by nature

  The formation of this impressive landscape is the result of the forces of nature. The rocks, which are of limestone origin, were formed in a marine environment over 200 million years ago. The tectonic movements that gave birth to the Alps then carefully folded the rocks to raise and form this massif, which was then exposed to erosion. Finally, the cirque at the bottom of the Combe was hollowed out and shaped by a glacier over 20,000 years ago. These gigantic limestone cliffs are just the visible part of the mountains that stretch higher up.

  Fauna

  A glimpse of Alpine wildlife

  The Fond de la Combe, at around 1,000 m elevation, is surrounded by a number of gigantic mountains that exceed 2,500 m in elevation. This variation in altitudinal range creates a wide variety of natural environments, which are home to almost all the animal species found in the French Alps. The most well-known of these are the marmot, golden eagle, griffon vulture, bearded vulture, chamois and ibex. You can see the ibex from wherever you are: instead of looking for this talented tightrope walker in the meadows or forest, look for it on the cliff faces in front of you. All these species are easily visible to those who take the time to observe while keeping a low profile!

  You are in a protected area!

  This spot marks the entrance to the Sixt-Fer-à-Cheval/Passy National Nature Reserve. The reserve is managed by the Conservatoire d'Espaces Naturels de la Haute Savoie, which is responsible for managing, protecting, and developing this natural area. The reserve is open to the public and is very popular, which means that it is subject to regulations designed to protect species and habitats. Rangers are on hand to answer any questions you may have and to ensure that these regulations are respected.

  Fauna

  Birds' hideout shelter zones on cliffs

  Sunny rocky escarpments attract feathered species of all kinds for several reasons. Firstly, they create ascending air currents, which are very useful for large birds of prey to gain height and move around without wasting energy. Secondly, they provide refuge, nesting and feeding areas for many birds. In this protected area, these environments are reserved for them: disturbance in the wrong place at the wrong time by paragliders, drones or any other human activity during the breeding season could result in failure to reproduce for the birds.

  Geology

  The all-powerful nature

  The knowledge we have acquired over the years means that we can now understand the natural hazards in our mountains. However, while some of them can be predicted, their scale and consequences still seem just as uncontrollable. Although the bottom of the valley appears to be flat and fairly wide, the slopes on either side of the valley are ideal for avalanches and rockfalls. The effects of these avalanches can be seen for much of the summer, with snow still present at the foot of the cliffs. Keep your distance, as the ice caves they form could collapse at any moment. In winter, a government order prohibits access to the site!

  Livestock guardian dogs 

  These are guardian dogs, so their use is permitted in nature reserves. They are there to defend sheep and lambs from attacks by large predators, such as wolves. Often large in size, these dogs, known as "molossoids", dedicate their lives to protecting the livestock to which they are deeply attached. When approaching the herd, it is important to remain aware of their attitude and to adapt to it, while following simple instructions: - Keep your distance from the herd (go around it if possible) - Call out loudly to the herds and dogs to avoid surprising them - Stay calm and avoid sudden movements, keep walking without running. Don't hesitate to speak softly to them so that they get used to you and accept your presence. - Avoid looking dogs in the eyes and try to ensure that you always have an object or an obstacle between you and the dog.

  Flora

  Floral diversity

  The great diversity of the area's natural environments has given rise to a rich floral variety: there are 942 species of plants, 63 of which are rare or protected. At a moderate altitude of around 1,000 m, this trail is rather unusual! it is home to species that normally can only be found at a higher altitude: this is due to the steepness of the slopes, where avalanches and floods bring in plants or seeds from higher up.

  Traces of the past

  The first humans to settle here had a lot of courage. There were very few flat areas, forests covering the valley, devastating natural hazards, and a winter that lasted 6 months... As they settled here, they also adapted their techniques to the limitations of the land, particularly the slopes, and adopted a way of life dictated by the seasons. The architecture, landscapes and local traditions of the village reflect the way of life of bygone days.
