ギレストルの峡谷・トップ5

An almost fairytale passage, the Guil has carved the rock over millions of years.

Incredible road, you enjoy it even more on a bike.

Cycling through these gorges is a wonderful experience.

The climb to the Col des Houerts terminating the Bua valley (Val d'Escreins) offers a mineral and wild view. If you hear rolling stones, look up and you will see ibexes or chamois.

The Ruine Blanche ravine is a formation of gypsum that was deposited in the lagoons of the Alpine Ocean. The alpine ocean was a warm, shallow sea where corals lived (fossils from the Rochebrune massif in Arvieux). In the shallows swam ammonites (fossils from the pink marble quarry of Guillestre). In the lagoons were deposited gypsum (formation of the Ruine Blanche above the hamlet of Montbardon in Château-Ville-Vieille) and cargneules (Casse-déserte in Arvieux). Fossilized sea sands, wrinkled by the waves, still bear witness to a beach. The clay and limestone sediments deposited on the ocean floor were then transformed into shales by tectonic phenomena.

Vallon des Pelouses you just run into a herd of sheep. Greet the shepherd and watch the dog, for he is very careful to protect his flock.
