Biol walks

A forest where you feel at peace. According to legend, the Vallin forest in the commune of Saint-Victor-de-Cessieu was frequented by druids and Templars who came to enjoy its healing properties. Several places in the forest are said to be full of energy, and there is a special energy in this place that confuses compasses. It is a pretty forest of beech, oak and hazel trees. Part of the forest has been replanted with Douglas firs, cherry trees and red oaks.

This walk allows you to discover the castles of Pupetière and Virieu. You first walk along the Bourbre valley on the hillside, then through the forest, passing the Croix du Moine Mort, and finally return to the hill towards Virieu.

A day's walk, quite lovely and varied. You start by going through the Grand Platon Forest, then going along the south-east bank of the lake with beautiful views over the lake. You change banks and go along the Feydelière and Véronnière marshes ('Marais' - protected sites). The return is via the north-west bank of the lake with beautiful views over Chartreuse and, if the weather is clear, Mont Blanc.

A lovely loop if you fancy an easy, not too long, shady walk, starting from the Chapelle-de-la-Tour car park, with no special equipment required. You could potentially spot ponies, horses, cattle, etc. We went in May, so we recommend going in the morning for the shade and milder temperatures in summer.

You climb the hillside of La Côte Saint-André (ND de Sciez) from where you have a remarkable view: from the Monts du Pilat in the west to the Mont du Chat in the north-east, passing through the Vercors, Belledonne and Chartreuse.
