Park in the car park of the former Criel school.
(S/E) With your back to the school, head left towards Rives. Pass a dead-end on the left, then turn left at the next junction to follow Chemin de la Sure. Continue for 200 m until you reach an EDF transformer.

(2) Before reaching the right-hand bend, turn left up the hillside onto Chemin du Fay, which overlooks the Allivet site, then the cutlery factories, before coming out onto a tarmac road at a hairpin bend.
(3) Follow the road down to the right for about 300 m.
(4) Turn left onto the Sentier de la Roche. The Chemin de la Roche is one of the paths (along with the Chemin des Écureuils) used by the inhabitants of Criel to reach the factories at the bottom of the valley, where the water power was located. Forges, sawmills, weaving mills and paper mills provided a livelihood for hundreds of people from Criel and the village of Renage for several centuries.
(5) At the end of the Sentier de la Roche, head up to the right onto Rue Alexandre Raphaël. Once at the end of the street, turn left, pass an old bread oven and arrive at the old school in Criel (S/E).
