Take the D14 road to La Rochette (either from Col de Manse or La Bâtie-Neuve). Park in the hamlet of Les Guérins (1,179 m), near the information board.
(S/E) Head up the D14A road towards the village of La Rochette. After two hairpin bends, pass the cemetery and continue for 200 m until you reach the path that climbs to the left.
(1) Take this path, following the yellow markings. Join the road briefly at a bend, before continuing north-east. Join the road again and take it to the left until the next intersection.
(2) Turn left and take the forest track for about 150 metres until you reach the fork (multidirectional signpost).
(3) Continue left, heading south-west, and go past the barrier, towards the summit of Chapeau de Napoléon (600 m further on). After 400 m, the path turns left, heading south, and climbs more steeply.
(4) Arrive at the broad summit of Chapeau de Napoléon and walk a little further to enjoy a panoramic view of the Gapençais (area secured by a barrier). Descend by retracing your steps to the previous intersection.
(3) Take the path on the left, below, heading west towards Les Guérins.
(5) Elevation 1339. Continue along the path opposite, slightly downhill, before reaching some fairly steep hairpin bends to join another track.
(6) Turn left and continue along the track, which becomes a path under the cover of trees.
After a steep and stony descent, heading south-west, leave the woods and walk alongside pastures and cultivated fields until you reach the small road (D14).
(7) Continue downhill for 200 metres to reach the Guérins car park (S/E).
