Mialan (cours d'eau) - Affluent du Rhône walks

A circular loop around the Crussol massif, passing by the three castles in the commune of Saint-Péray. Its main attraction is the quick ascent to the Crussol ridge, offering views of the Rhône valley and Crussol Castle from above on the south side. The route takes an hour to walk, but feel free to allow twice that time to enjoy the sites you pass through at your leisure.
