For those without a car, there are two bus routes serving Manthes from the towns of the Rhône Valley (numbers 2 and 12) and from the surrounding towns to the east and south.
(S/E) From the car park at the church priory, head down to join the Montée de l’Église and take the Chemin des Plantèes on the left for about 80 metres. Turn right onto Rue de Montfray. After about 250 metres, ignore the road branching off to the left and take the path continuing straight ahead. Cross the Torrent de Combet, continue along the Chemin du Buissonnet and pass between the farm buildings to reach the Y-junction.
(1) Turn right onto Chemin des Piérrards and continue straight on until you reach the D139. Turn right onto it, then immediately left after the Combet stream bridge. Continue straight on. In this section, you can see the fish farm. As you leave the woods, turn right for 60 m.
(2) Turn left towards the hedge and continue to the right to reach a path. Take this path to the right, slightly off the main track, and continue straight on to reach the small bridge on the left.
(3) Turn left onto Rue de Port de Jonc, take the first path on the right and immediately cross the small bridge on the right to continue through the middle of these pools of water.
(4) Turn right at the first small passage, continue to the left to reach the main road (Rue des Sources). Follow it to the right for about 150 m, then take the Montée de l'Église on the left. After about 120 m, a narrow staircase leads up to the church car park (S/E).
