The Authion hike

The paved road is divided into two, and you want to take the road that rises to the left and continues for 1.2mi. You can admire the panorama to the South, the Côte d’Azur, and the Provence mountains.

After 1.2mi, you will come to a pass where there is a low building. Take a right on the trail that heads into the larches towards the Mille Fourches Fort, which you will reach in less than half an hour.

The Fort, built at the end of the 19th century, was restored in the ‘30s with two reinforced concrete posts. From the fort you can enjoy a wonderful view of the Alpes Maritimes, the Ligurian Alps, and the French Riviera.

Go back towards the low building, and take the military road on your left that, with a gentle slope and long bends, climbs up to Fort La Forca, which is Mille Fourches twin structure. Just below the fort there are the barracks that once hosted garrisons all year long.

From the highest point you can enjoy the view on the Reducte des Trois Communes, the symbol of the Authion fortifications. You can also see the Hautes Alps and the tops of the Valley of Wonders, the Grand Capelet and the Bego.

Continue along the crest and reach a path, with a signalling pole. Continue on the right until you reach the Reducte des Trois Communes, passing by the barracks.

La Redoute was built in 1898; it once housed 50 men and controlled the access from the Roya Valley. In 1945, during the war, it was damaged.
On the South slopes, 328ft below, is the Plan Caval defensive system, with trenches and bunkers from the 19th and 20th centuries.

From La Redoute turn back you’ll reach a familiar junction on the pass. Continue straight, to the west on the crest. You’ll reach the parking lot in less than 30 minutes.
