The starting point is the "Saint Zacharie Centre Ville" stop on bus lines 8 and 9 of the Pays d'Aubagne et de l'Étoile. Plenty of parking spaces in the town centre.
(S/E) Leave the bus stop via the main road heading south (Aubagne). Continue to Place du 4 Septembre, where there are large plane trees.
(1) Turn left towards Plan d'Aups (D480) and continue to a crossroads with a small fountain.
(2) Turn left onto Avenue Jean Moulin: follow the red/white GR® and red/yellow GRP® markings. When you reach a gate marked "La Castillonne", turn left onto the path, following the double markings. At the next crossroads, continue straight ahead, ignoring the sign for "Hostelllerie de la Sainte-Baume" on your right. You will come to a track with a pumping station on your right marked "Saint-Zacharie Service des Eaux".
(3) Turn right and immediately after, at the fork, turn left onto the pretty path that runs alongside the Huveaune. You will come to a junction with a path that climbs to the right.
(4) Take a few steps to admire the lock and the fairy of the spring, a statue that is part of the five fairies of the Huveaune, placed along the river in 2013. Return to the crossroads.
(4) Turn left onto the path that climbs uphill, then turn left onto the track that runs alongside the Huveaune. Keep left at the next junction and you will come out onto the D560.
(5) Turn left and follow the road carefully until you reach the "Saint-Zacharie ZI" bus stop.
(6) Turn right onto the tarmac road towards Nans-les-Pins, Vallon de l'Espagnol. At the rubbish bins, keep left onto the dirt track towards La Gantesse.
(7) At the three-way junction, follow a dirt track that branches off to the right towards "Nans-les-Pins". Further on,
pass a path on your right that heads uphill. At a right-hand bend, a small path (not shown on the IGN map) branches off to the left: stay on the track. Cross a flat area and you will reach a crossroads.
(8) Take the path on the right, leaving the double markings. The path runs along the ridge.
(9) At this point, a parallel path appears on the left: take it and head back downhill (due east). The path winds down the southern slope of the hill. Beautiful view of Sainte-Baume. You will reach a wide track with a cistern marked SZE1.
(10) Follow this track to the right until you reach a clearing.
(11) Ignore another track that branches off to the left and continue straight ahead, ignoring a path and then a track that branches off to the right. You will rejoin the D560.
(5) Cross it carefully and take the track opposite, towards Saint-Zacharie. Do not take the path on the left and go straight past the chain. At the fork, turn right to return to the lock and the fairy.
(4) Turn left and rejoin the track near the pumping station you saw on the way there. Continue a few metres to the right.
(3) Turn left towards Saint-Zacharie (walk along the fence as you climb). At the next crossroads, head towards Saint-Zacharie and not Hostellerie de la Sainte-Baume, arrive on Avenue Jean Moulin and follow it to the right.
(2) Turn right: wash house on the right below.
(1) Turn right onto Rue Jean Jaurès and head for the bus stop next to the Bar des Sports (S/E).
