(S/E) With your back to the car park, head towards the cross then take the path between the trees to reach the imposing chapel. Note the door on the right and its ornamentation. Walk round the chapel in a clockwise direction to get a better sense of its size.
Follow the small road that runs alongside a beautiful property and leads to a junction opposite a new-generation transformer.
(1) Turn right then left, following the small road. Turn right, following the signposting, onto a small track that leads to a road. Follow this 30 km/h road to the left until you reach the next track.
(2) Turn right onto this uphill track. The wind turbines are in sight. At the MTB signpost, turn right onto a grassy track that runs alongside a wetland (potentially muddy in winter). You’ll emerge at a meadow.
At the junction with a wide path, leave the path to the right towards the hamlet of Kerziouret and continue north-east, still skirting a wetland.

(3) Turn right onto the path that heads straight uphill and, at the end, turn left to go round the large hamlet of Kermenguy. Continue straight on, ignoring the small road on the right and those leading up to the hamlet.
At the next junction (grove and pylon on the right), continue straight on along a dirt track that turns left then right before joining the access road to the wind turbines.
(4) Turn right towards the south, using the plastic paper factory on the right as a landmark. At the road, take the disused road on the left towards the D784, which you will join.

(6) Turn right into a reforested area dotted with five exercise stations and arrive at a car park. Continue straight on towards the site of Saint-Ronan’s Chapel, its fountain and its sarcophagus.
(7) Retrace your steps, take the track leading to the car park and join a small road at the hamlet of Mespirit.
