Take the old (magnificent) road from Flassan to Sault and park easily at the hairpin bend (altitude 891m).
(S/E) Walk up the valley for 400m until you reach a fork.
(1) Take the track that branches off to the left in a hairpin bend. Follow it for about 800m, ignoring two tracks branching off to the right. Pass the Fontaine Breyguette (water not drinkable). Join a wide track and head down to the left for a good hundred metres.
(2) Turn onto the path that starts on the right. Follow it for about fifty metres; a few fallen trees might make you hesitate.... It winds its way through a magnificent natural forest where many plant species grow side by side. Pass numerous small firebreaks on your right and continue slightly uphill until you reach a track.
(3) Turn right to follow this gently descending track until you reach a track suitable for vehicles which climbs towards the Chapelle Saint-Jean (signposts – altitude 969m – Chapel 600m). Turn left to climb this track. A second signpost appears shortly afterwards: it is clearly in the wrong place as it should be further on.
(4) Continue straight along the track.
(5) Turn left and head for the chapel.
(6) Saint-Jean Chapel: a magnificent spot in the woodland, with pine, oak and beech trees dating back a century. Walk round the chapel and head north for about fifty metres for an extraordinary view of the summit of Mont Ventoux.
Continue along a very pretty path heading east, initially flat, then slightly downhill to reach the bottom of the valley. Continue to the right to climb back up.
(7) Take the path on the right, which widens as it climbs through the forest to a large crossroads. Take the level track on the right. Follow it for 300m to a completely open area offering superb views of the Nesque and Luberon plateaus.
(8) Turn left onto the track which descends slightly. When the slope becomes steeper, take a small path branching off to the right (shortcut) which rejoins the track about a hundred metres further down. Continue to the bottom of the valley.
(9) Turn right onto another track that descends the Ravin des Boyers.
(1) Continue straight on to return to the starting point (S/E).
