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.

The Trévans gorges form a narrow canyon bordered by steep sides with high cliffs cut into Jurassic limestone. The fauna is varied since there are around forty species of birds and bats. They are also home to chamois. The fish population of Estoublaïsse is made up of brown trout and bullhead, a protected species. The flora is remarkably diverse between plants typical of the Mediterranean climate (terebinth pistachio) and plants from the mountain environment (larch), hence its classification as a Sensitive Natural Area of ​​the Department, State Biological Reserve and Natura 2000.
