The walk starts next to the "Vert Yzeron" sign, not far from the Chemin des Fonts roundabout.
The walk is accessible from the TCL bus stop “Sainte-Foy Les Sources” (Bus 90).
(S/E) Follow the path as it descends gently alongside the stream (on the right-hand side of the path). Cross the stream and now follow it on your left.
(1) Ignore the path on the right that leads back up towards the Chemin Antoinette housing estate. Continue until you reach a wooden gate and a car park.
(2) Turn around and return to the starting point via the same path (S/E).
