Route Description for Fontanalba
From where you’re parked, take the dirt road on the left, following signs to "Fontanalba". The road, built in the ‘30s for the war, steeply rises, but then - after twenty minutes of walking - flattens out, overlooking the panoramic valley of Fontanalba. Mount Bego, a sacred mountain for the ancients, stands in the background.
After about one hour of walking, you will reach a junction with a sign for the Lac de Grenouille, or Lake of the Frogs, which, with a deviation, you can reach in fifteen minutes.
If you continue straight, you will arrive - after fifteen minutes - at the Gias of Fontanalba, where the road divides. If you head straight down you go back to Casterino; if you go right you’ll continue up to Fontanalba. After another quarter of an hour, you reach the refuge of Fontanalba, which is closed for repairs, but could be open in 2018. You will leave with the refuge to your right.
The road will delve into a forest of larch trees. Pay attention. The rocks are particularly unstable here and after the thunderstorms there may be rockslides. Continue up to the bridge where - in summer - you can normally meet a ranger who will give you information about the accessibility to the area of rock engravings.
After crossing the bridge, you’ll see a path on the left indicating to "Lac Vert". The lake is a good place to have break or relax under the shade of the trees, and it’ll only take 10 minutes to get to. Here you can enjoy some of the most beautiful scenery in the Roya Valley.
Walk along the lake. After ten-minutes of climbing, you’ll reach a junction. The path on the right brings you to the first rock engravings, which are visible a few hundred meters.
Going back to the junction, you’ll continue close to a little river and that’ll lead you to the Lac Jumeaux, (twin lakes) where you can relax and eat lunch.
To finish the tour, you can continue up to the Ranger’s shelter. To the left of the shelter are some panoramic views. Here the views of the valley and the Ligurian Alps are truly exceptional.
A little further and you begin to walk down through the "Via Sacra" (the “Sacred Road”), one of the most famous sites rich in rock engravings of the Neolithic and Bronze Age. A descriptive panel reveals some of the meanings of these engravings.
At the bottom of the Via Sacra, continue on the right along the path. After a quarter of an hour, on this military road, you’ll arrive at the bridge from before.
