Access: At the entrance to the village of Saint-Zacharie, take the D480 towards Plan d'Aups.
Pass the Pont d'Angèle bridge and park 1.2 km further on, on the left in a car park by the roadside.
(S/E) Take the paved road north for 150 m, then follow the blue and yellow trail that climbs to the right towards the east into the hillside.
(1) At the first fork, keep left and follow the blue markings until you reach a track.
(2) At the signposts, turn right onto the track that climbs uphill and follow the yellow markings.
(3) At the fork, turn left, follow the yellow trail and, once you have passed the cistern, take the right fork and follow the yellow trail (do not take the S47 Bellevue track). Leave two paths on your right and join a star-shaped crossroads.
(4) Turn right and continue for 150 metres. Then follow the yellow trail and the red and whiteGR® trail to the bottom of the Huveaune valley.
(5) At the bottom of the Huveaune valley, at the Saint-Zacharie and Hostellerie de la Sainte-Baume signs, follow the river downhill to the left for about 100m. At the La Sambuc sign, cross the river on the right to reach the other bank. Take the wooded path on the right that goes up the gorges, keeping the river on your right, which will allow you to avoid the stifling heat of the main track. Keep the river bed on your right at all times.
(6) Cut across a track and follow the path on the right above the track. After 150m, join this track and follow it. At a ford, follow the path on the left, keeping the stream on your right.
Rejoin the track at another ford and follow it to the next one.
(7) At the sign for Forêt domaniale de la Sainte-Baume, site Silvo-Pastoral de la Taurelle, do not cross the river but turn left onto the path marked with a yellow cross and a red and white cross. Leave the small wooden bridge on your right, then at the fork, take the path marked with a yellow cross on the right. Leave all the paths on your left and rejoin the track.
(8) Turn right onto the concrete bridge, then left towards the S36 Les Ascles sign. Pass the cistern and continue straight ahead. Just after the biological reserve sign, take the small path that branches off to the left (small cairn) and follow the riverbed through the undergrowth.
(9) At the crossroads, continue straight ahead and keep the river on your left. After seeing some beautiful waterfalls and yellow basins on the other bank, you will see a wooden sign and a wooden footbridge. This is the Source de l'Huveaune.
(10) Turn around and retrace your steps to the small dirt crossroads.
(9) Head uphill to the left towards the west to reach a large dirt track. Pass the water pumping station and, 150 metres after it, at the pass, take the right fork that descends.
(11) At the bottom of the valley, turn left, cross the dry riverbed and turn right. There is a green patch on the ground. Further on, keep to the left and when you see the fields, keep them on your right until you reach the large dirt track on the right. Turn left and follow the track back to the car (S/E).
