Park in the large car park at Le Martinet, on the west side of the bridge over the Gardon de Sainte-Croix, near the Le Martinet restaurant.
No markings (yellow markings in the opposite direction)
(S/E) From the car park, head away from the bridge and the direction indicated for the Sentier d'Auriol, following the Gardon de Sainte-Croix as closely as possible. This will take you to the start of the narrow dyke between the river and the millstream, a canal partly dug into the rock. If the stones are wet, do not attempt to cross, as wet schist is very slippery. Otherwise, cross the dyke, taking care. In some places, where it is narrower and more damaged, it is better to get off and walk a few metres along the irrigation channel, which is usually dry. You will arrive at the Païssière (small dam) de la Cascade site.
(1) Return to the car park (S/E) by retracing your steps.
