(S) In Séranon, from Borne 192 (B192), to the right of the town hall, take the path that climbs slightly, following theGR®510trail to the west (red and white markings).
Pass by the new cemetery and join the paved path that climbs towards the church (closed) and the old cemetery. From there, you will have a lovely view of Notre-Dame-de-Gratemoine on your left.
(1) At a hairpin bend to the right, continue straight ahead (west) on theGR®. Immediately after (less than 100m), two paths separate: an unmarked path on the right and theGR® on the left, which begins to descend slightly (it is this second path that is shown on the map). These two paths remain parallel and meet at the Sainte-Brigitte Chapel (excellent acoustics): either one can be taken.
(2) Continue straight ahead (west) after the chapel (B214) on thePR® trail, which is marked in yellow but not very visible. Follow this trail to the bottom of the ruins of Vieux Séranon.
(3) Turn right onto a path that crosses the ruined village and climbs up to a small pass. (head west, then 100 m further on head northeast, then 200 m further on head north).
(4) Continue for about ten metres opposite, slightly downhill, to rejoin the B194. Leave theGR® and turn right (east) to follow the yellow markings.
Caution: do not take the dangerous path that runs along the ridge; stay below on the north side.
The route continues through pleasant woodland, alternating between gentle descents and ascents.
(5) Shortly before the summit, the climb becomes steeper, but there are flat sections where you can catch your breath.
(6) At the summit, you can enjoy a breathtaking 360° panorama. The descent, still following the yellow markings to the east, is obvious. It is steep at first, so be careful as the rocks can be slippery. The trail then turns north-east. You will reach some reservoirs (located to the right of the yellow marked trail, contrary to what is shown on the IGN map).
(7) Take a wider path (still marked in yellow) and reach the D80 road just before the B181 (B182 not marked when we passed through). Take the road on your left for a few metres until you reach a cross.
(8) Head south on a path (signposted Caille) which runs alongside a pretty property with a chalet for a few metres. Cross the D79, continue along the path and you will reach Caille without difficulty.
(9) Turn right onto Rue Centrale, pass the post office and follow the road to the B197.
(10) At this signpost, turn right onto a wide path. At the next fork, take the path on the right and continue west to reach the town hall of Séranon.
