There is no car park as such, but there are a few parking spaces along the D15 between Coaraze and Col Saint-Roch at marker 197.
Warning: if storms are forecast locally or upstream, do not venture into the stream bed and avoid staying on the banks.
(S/E) From marker 197, climb towards the "Ruisseau de Planfaé". This is the only "difficulty" of this outing because the climb (and therefore the descent on the way back) is steep and slippery, but short.
(1) At marker 196, turn right towards "Col de Saint-Roch". Follow an old path (military, I think, given the characteristic kerbs and retaining walls) through pleasant undergrowth that is cool in summer.
(2) At marker 195, take a sharp left turn. The path is not very visible at this point, so pay attention.
Be careful, shortly after marker 195, the yellow markings are misleading and tend to make you turn right (also marked in yellow). Do not take this path, which descends steeply, but continue straight ahead towards the east.
(3) About 500m further on, you will reach marker 196a, at the edge of the stream. You can cool off and follow the stream for a few hundred metres downstream, without any equipment, through a beautiful wild canyon. Return to the crossroads.
(3) Turn right and follow the path to the junction at marker 196, which you passed on the way there.
(1) Take the same path back to the car park (S/E).
