The walk starts at the bottom of the 100-step staircase on Houlgate beach, in front of the entrance to the Camping de la Plage campsite. There is a small free car park in the street leading to the campsite, about 100 metres before it.

At the end of the street, after the right-hand bend, you will come to the steps leading down to Villiers-sur-Mer beach.
