Parking is available on Chemin de Tourris at the Revest quarry, near the Turcots trail.
(S/E) Walk up this wide track until you reach a fork.
(1) Take the left fork. Continue climbing steadily, ignoring the paths on the right and left, first heading north-west, then north and finally north-west again. You will reach theGR®99(red and white markings).
(2) Once you reach theGR®99, turn right. Continue on theGR®, ignoring the path on the left.
(3) About 50 metres further on, turn onto the path on the right. Leave theGR® and follow the path eastwards, which passes close to the karstic cave du Sarcophage. The latter is on the right-hand side and you will need to look for it in the undergrowth.
(4) Retrace your steps and continue through the undergrowth on the path that bends to the right, runs alongside the high-voltage line and then continues straight below it, crossing several sharp limestone pavements, heading south-west. Be careful, as there are no markings... However, a few cairns mark a rough route. Then turn left at a 90° angle and then right to join a path marked in blue.
(5) Take this blue trail on the left, which crosses the famous "stone glaciers" dotted with spectacular crevasses and leads to the summit of the Pyramide de Cassini and its antennas.
Be careful, as the going is difficult and strenuous in places.
(6) With your back to the pyramid, take the path on the left to return. This path descends through the undergrowth to the Turcots trail.
(1) Turn left and follow this track downhill to return to your vehicles at the starting point (S/E).
