Depart from the car park of the CERGA Côte d'Azur Observatory.
(S/E) Opposite the observatory, turn left, follow the path northwards and cross the road leading to the observatory. Head towards a ruined hut and a small building resembling an oratory. Continue to a beautiful sinkhole and a hut on its western side.
(1) After that, there is no path, so keep heading north-northeast, following the sinkholes and huts. Cross theGR®4(shown in purple on the map). A few hundred metres further on, cross a track. Then turn left (west) then right (north) and pass the Poumeires and karstic cave sheepfolds, then along low walls used for cultivation. Climb north to a magnificent enclosure with a dry stone hut, low walls and a few wild cherry trees.
(2) Turn west and climb the ridge of Colline de Vaumeillane to the cairn at the summit. Descend westwards through a few scattered pine trees. Cross another north-south track and reach a beautiful hut near an enclosure.
(3). You will come to another hut 200 metres to the west and a ruined enclosure.
(4) Descend southwards: there is another hut above a sinkhole; they are everywhere...
Head southeast to the Cabane de la Baume, built above a karst collapse.
(5) Heading east-southeast, about 60 metres away, you will see another deep collapse with two large trees emerging from it. A few dozen metres to the northeast, you will see a sinkhole 30 to 40 metres deep (elevation 1225).
Head south-southeast to find an enclosure and a hut 250 metres away.
(6). Cross theGR®4again. Continue 50 metres further in the same direction to reach the last hut above the sinkhole.
(7) Join the black trail leading to the observatory and retrace your steps back to the car park (S/E).
