This trail offers spectacular views, discover the gardens and ruins of Valbonnette before a panoramic return to the gorges. The torrent "l'Estoublaïsse" has dug, in the Jurassic limestone, a narrow canyon 200 meters high.
Description
Starting from the parking lot set up on the edge of the Trévans road (D667).
An emblematic walk in the Trévans gorges, the path follows the Estoublaïsse on the right bank then the left bank. It then crosses a tributary twice, "le Clovion", called on the maps "le Pas de l'Escale". This first part leads via beautiful ledges (very narrow steps on the mountain slope) to the intersection of the path of the Saint-André chapel, revealing Mediterranean flora. Continue straight on to reach the Valbonnette gardens and its tranquility. After a shady crossing (larch, alpine flora), the path passes in front of the ruins of the hamlet of Valbonnette then joins that of the Belvédère. Return via a steep descent overlooking the Gorges towards the starting path.
The Trévans Gorges form a narrow canyon bordered by steep slopes with high cliffs carved into Jurassic limestone. The fauna is varied, with around forty species of birds and bats recorded there. They are also home to chamois. The fish population of Estoublaïsse is composed of brown trout and bullhead, a protected species. The flora is remarkably diverse, ranging from plants typical of the Mediterranean climate (terebinth pistachio) to plants from the mountain environment (larch), hence its classification as a Sensitive Natural Area of the Department, a State Biological Reserve, and Natura 2000.
