From Seyssins or Seyssinet-Pariset via the D106, pass the hamlet of Pariset, which is situated just after the Tour Sans Venin. Park along the road at the hairpin bend that turns to the left. There is a small car park with a few spaces at the start of the walk.
(S/E) Cross the road carefully and head due north. A good path winds its way up through the Bois des Travers. Ignore a level path branching off to the right and another climbing more steeply to the left; the path leads to fenced-off fields at an altitude of around 940 metres.
The path runs alongside them on the right before eventually approaching the top of the cliff overlooking the Bois des Vouillants.
(1) At around 1,000 metres, look out for a fairly steep path on the right. It quickly leads to a narrow, vertiginous promontory, which is none other than the destination of this walk; the final section is equipped with a fixed rope, which may be useful if the ground is wet or snow-covered.
(2) The return journey follows the same route as the outward journey to the small car park (S/E).
