You can reach Serres by train or car. Park in the large car park on the banks of the Buëch.
(S) From the centre of Serres, follow the signs for Col de Saumane. Climb up to the heights of the town through the charming medieval streets, following the red and white markings of the GR® 946. Once you leave Serres, between the forest and the rocks, the splendid path overlooks the town and the Buëch Valley. Reach Col de Saumane.
(1) Continue on the GR® 946 towards Serre de la Bouisse until you reach Rocher de Jardanne.
(2) Leave the GR® and follow the yellow PR® markings on the right, which will take you along the ridge to Serre de la Bouisse. Stay alert on thefirst part, as the markings are sometimes discreet. The path along the ridge is fabulous, offering views of the various passes and ridges you will be crossing over the next few days on the Tour des Baronnies. Between the peaks of the Southern Alps and Mont Ventoux, the 360-degree panorama stretches as far as the eye can see. You will come out at Champlat.
(3) Leave the ridge and turn right into a beautiful forest and countryside setting. Arrive at the Col d'Anon and its rest area, where you will rejoin the GR®94.
