Description
And strange marine mammals called the sirenians inhabited our lands... 40million years ago, the col des Lèques was under the sea. In this warm sea lived peaceful marine mammals: sirenians (ancestors of the current dugongs and manatees). In a unique place in the world, set up by the Haute Provence geological reserve, you will discover remains from 35million years ago. From the car park at the Col des Lèques, take the path along the campsite. In 500m, follow the path and find a small pass and an intersection of marked trails. 1 - Go left and leave on the right the trail going up towards La Baume. Find a ruin by the relatively flat and shaded path. Pass by and then find a small footbridge. After crossing it, climb the trail with a few wooden steps under the pines. Cross the next valley and find a view of the Col des Lèques, the north face of Cadières de Brandis and the summits of Robion and Destourbes, dominating Castellane. Go down the path and go to the right in the direction of the valley where the sirenian fossil site is located. 2 - The same route is used for the return.
