On the southern fringe of the Vercors, the valleys of the Gervanne and Sye rivers form an outstanding natural and landscape ensemble.
Strong climatic contrasts, a rugged landscape, high-quality peasant farming, lipid rivers and unspoilt natural environments allow wildlife to express itself in all its diversity.
From the chamois to the phasme, from the beaver to the vulture, from the woodland tulip to the Drôme ophrys, this concentrate of nature is a marvellous invitation to observe, to photograph, to dream, to walk sensitively... With all the respect this fragile heritage deserves.
