The start is in the commune of Le Gua, at a place called Les Petits Amieux. You can park below the hamlet at the side of the road.
(S/E) Take the track heading north towards the hamlet of Les Grands Amieux.
(1) Just before the hamlet, turn left onto a good track that climbs towards L’Échaillon.
(2) Directly beneath the power line, take the track on the left. Just before a building, look out for a path on the left that climbs towards Pas de l’Échalier and the village of Prélenfrey.
(3) Ignore the turn-off to Les Vincents on the right and continue to the hamlet of Baleyère. Proceed to the junction marked by an iron cross on the right.
(4) Take the small road on the left which descends towards Prélenfrey. Continue downhill towards the church, pass in front of it and reach the junction with the RD8B.
(5) Head straight ahead and carefully follow the main road for about a hundred metres, then turn left onto Chemin de la Charrière. Continue downhill to the sewage treatment plant, where the tarmac road ends. Carry on along a good track until you reach the Ruisseau de Jonier.
(6) Turn left to follow the stream and rejoin the RD8b. Follow it downhill for about a hundred metres.
(7) Cross carefully and take a good track that leads directly back to the hamlet of Les Petits Amieux. Walk through the hamlet to return to the car park (S/E).
