If you are coming from the north, via Lançon-Provence: take the D113 departmental road (towards La Fare-lès-Olivier), continue for about 700m after the sign for the Col du Télégraphe Chappe. There is a small space at the side where you can park.
If you are coming from Le Dud, via La Fare-les-Olivier: take the D113, but do not attempt to cross the road as it is far too dangerous. Continue to Lançon, turn around at the first roundabout, then follow the instructions above.
(S/E) Go through the barrier and take the path that slopes slightly downwards. After 50 metres, you will come across an underground oil pipeline, marked by blue markers and yellow signs.
Turn left and follow the pipeline until you reach the edge of the plateau.
(1) You will see a large rock in front of you with some remains of dry stone walls: these are the ruins of the Grenier de Coudounèu farm. For more information, see the link below.
PLEASE NOTE: you can visit the site, but the farm is on a rocky outcrop with steep drops.
Leaving the farm and returning towards the oil pipeline, take a path on the left (marked with three blue circles next to three orange circles). Follow the path and you will see the Chappe telegraph on your left. Pass it and you will come to a crossroads.
(2) The aforementioned markings turn to the right. Instead, take the path on the left. Shortly afterwards, you will arrive at a crossroads with a viewpoint over the Étang de Berre. Turn left towards the Chappe Telegraph and walk to the small building (a link below will tell you more about the Chappe Telegraph).
Retrace your steps back to the crossroads.
(2) Take the path on the left. After 500 metres, you will come to a crossroads with a large bush in front of you, a path slightly to the left and another to the right at a right angle. Turn right (a few steps further on, there is a blue mark on the ground that is half faded). After about 100 metres, the path turns left and descends. After about 250 metres, you will come to a crossroads.
(3) Turn right and follow the path. You will eventually reach a wide path running alongside several properties. Follow this path to the right until you cross the oil pipeline (see the blue markers and yellow signs).
(4) Follow the oil pipeline and return to the starting point (S/E).
NB If you are heading north via Lançon-Provence, do not attempt to cross the D113 road as it is too dangerous. Continue to La Fare-lès-Olivier and turn around at the first roundabout.
