This description starts at the lower part of the circular route, at a place called Les Rives. There are one or two parking spaces along the road, otherwise park where you can.
It is perfectly possible to start from the top, from the church car park in Saint-Jean-d'Hérans (and therefore start at point 4 of the description).
(S/E) Below Les Rives, a path leads down towards a field. Follow it and, 50 metres further on, take another path on the right that descends and joins the forest. Do not go all the way to the field. Then follow the yellow markings for about 2 km, ignoring a few paths leading down to the Drac on the right.
The path becomes a trail, then a path again in the middle of the fields.
(1) At the Les Chaux sign, near the high-voltage power line, turn left towards Saint-Jean-d'Hérans. The trail joins a stream, which you cross to go up to the left. Do not go up along the stream. This trail becomes a path. Continue south-east.
(2) At the Caillat 1 sign, turn right, then 100 metres further on, at the Caillat 2 sign, leave the path and take a trail on the left.
(3) At the Tracot sign, turn left towards Saint-Jean-d'Hérans. The path descends steeply for a short distance, then becomes a good track and joins the D34B at the entrance to the village of Saint-Jean-d'Hérans. Enter the village and head for the church.
(4) A sign points to Les Rives, heading north. Follow this tarmac road, which becomes Chemin des Fontaines. Do not turn left downhill, but keep on the level path. Pass a telephone antenna, then the cemetery.
(5) At Grand Champ, shortly after the cemetery, a sign points to Paquier on the left. Take this path downhill to Paquier.
(6) Cross the tarmac road and take a smaller road opposite, downhill towards Les Rives. In the hamlet of Les Rives, follow the yellow markings to turn left horizontally, then take the second road on the right downhill towards the car park (S/E).
