Engravings and lakes of the Fontanalbe Valley

Walk along the Sacred Way of Fontanalbe and discover the rock engravings (-5000 years old) of the Sacred Way, at the foot of Mont Bégo (2872m). A genuine open-air museum and one of the Park’s essential sites.

The hike begins on foot – at marker 391 – on a non-driveable track. Head towards “Lac Vert”. When you reach the halfway point, you will be in the heart of the National Parc (marker 390).Take the path towards “Refuge de Fontanalbe”. If it takes your fancy, you can make a detour to the Lac des Grenouilles (Lake of Frogs). To do so, take the other path.
 At the refuge, marker 389 indicates the direction of “Lac Vert”. Take the path that starts just below the refuge, over a footbridge and up in the larch forest. When the hiking trail reaches the military track again, meeting point for the guided tours, follow the sign for “Lacs Jumeaux” on your right. The path comes to a bridge, still heading towards “Lacs Jumeaux”. Continue along the paths until you reach the lakes.This is also where you enter the archaeological zone: a discovery course provides free access to the protohistoric carvings of the Sacred Way and of the Cathedral. Just before the “Gias des Pasteurs”, a sign indicates two possible directions; one directly to Lacs Jumeaux and the other towards the Sacred Way (via a loop which ends with an orientation table followed by Lacs Jumeaux).For the return journey, follow the path which runs alongside Lacs Jumeaux, with a peat bog down below, until you reach a sign showing two directions; one towards Lac Vert and the other towards the end of the discovery course. In either case, take the path you used for the upwards journey and head downhill to return to Castérino.
