The walk starts on the small road to Bois Méans near Les Orres 1800. Park in the Pra Paisset car park; this is the car park for the Via Ferrata des Orres and also for the hike to Lake Sainte Marguerite and Le Pouzenc.
(S/E) The tourist trail starts with a gentle climb and passes in front of the shepherd's hut called 'Gavtier' on the IGN map.
(1) At the hut, there are benches, tables and a fountain for picnicking in the shade of the trees. You can also admire the pretty sheepfold, which has been restored and has a unique floor made of vertical wooden logs.
Continue along the main path for 700 metres.
(2) Cross the stream on the right, which leads to the starting point of the Via Ferrata des Orres. I did it in 2010 and it's superb. Be careful, you mustn't be afraid of heights.
Leave the stream on your right and continue along the path, which climbs steeply for about 850m.
(3) Be careful halfway along, before the big right-hand bend, you will need to leave the main path and continue straight ahead across the meadow.
(4) Turn right before the hairpin bend (if you continue straight ahead, you will reach the top of the Source de Jérusalem). Personally, we preferred to arrive at the foot of the waterfall.
(5) 700 metres further on, you will arrive at a junction of streams, including the one that comes from the spring. From there, you can see the rock at the top that gives rise to the waterfall. Two hikers told me about a barrier at the foot of the waterfall. One of them said, " There is a wooden barrier when you reach the waterfall, but if you carefully walk along it for about 3 metres, you come to a small path that leads directly to the waterfall." You will need to climb over the scree to reach the foot of the waterfall. When it's hot, it's wonderful to reach it and cool off. Be careful, as with all waterfalls, the rocks are slippery.
To return, descend the scree slope and, on the path, go down 100 metres then take the small path on the left that passes through the meadow. Return to the main path and head back to the car park.
Your legs are now warmed up and ready for more intense exercise over the next few days.
Return to the car park (S/E).

thank you
