The Valdolac

A beautiful getaway between Lake Paladru and the Ainan Valley, with views of some remarkable buildings (Grange de Louisias, Château de Longpra). You will follow the natural area of ​​the Marais de Chirens and end on the shores of Lake Paladru.

From Charavines this loop takes you into Valdaine to return to Lake Paladru via the Rivoires valley and the Bilieu hillsides.
You climb quickly in the direction of Louisias, from where you will see the thatched roof of the emblematic barn of the same name. In front of you, the medieval keep of the Château de Clermont stands out against the sky. The pretty descent to Chirens will make you discover, after the village, the natural space of the marsh of Chirens and its observation station at the edge of the road. You will then take small roads winding at the foot of the first slopes of the Chartreuse Regional Natural Park. After crossing St-Geoire en Valdaine, the village of 7 castles and gaining a bit of altitude, you will descend via the fairly steep slope of a wild coomb to Massieu. It is then by another green and gentler combe that you will reach St-Sulpice des Rivoires.
The panoramic route will then take you back via Montferrat to the heights of the lake at the level of the village of Bilieu, which offers beautiful views. To end this escapade, you will return by the greenway and the Bois d'Amour in complete safety to enjoy the blue waters of the lake.
