At the entrance to Barcillonnette coming from Vitrolles via the D20, continue to the junction near the town hall. On the right is a car park which serves as the start and finish point of the route.
(S/E) Take the Route d'Espréaux (the left-handmost of the three roads), which heads north-west and crosses the village towards the Col d'Espréaux. Continue for about 50 metres until you reach Rue de la Forge.
(1) Turn left to climb this steep, dead-end lane. At the top, ayellow PR®-marked trail branches off to the left. Follow this trail towards the Col de Peyssier. Apart from the section at the Torrent de Rousserand, the climb is mostly through woodland. Leave the woods and reach a large earthen platform, from which several tracks and trails branch off.
(2) From there, head straight ahead off-trail for about twenty metres to reach the ridge line on your right (north-north-west). Once you reach the well-marked path (which is not shown on the IGN map), you’ll have no trouble crossing over to the Col des Garçins. The path is wide and follows an electric fence for almost the entire length. To avoid taking a wrong turn, it is important to continue the crossing until you reach the sign marking the Col des Garçins.
(3) Turn right, towards Esparron or Barcillonnette. You are now on theGR®93, marked with red and white signs. After 300 m, the path rejoins a much wider forest track.
(4) At a hairpin bend, a signposted mountain bike trail allows you to cut across the next bend: if you miss it, don’t panic, you’ll soon be back on the forest track. After a very pleasant stretch through the forest, you’ll reach a rockier section and continue the descent to the Serre Claud signpost.
(5) Turn right towards Barcillonnette. The trail runs alongside meadows and ends on the Col d’Espréaux road (D20).
(6) Turn right and follow the road with care. Reach the village of Barcillonnette and walk through it. Return to the original junction.
(1) Continue straight on to the town hall and return to the car park (S/E).
