Information on how to reach the starting point, as well as details regarding difficulties, alternative routes and precautions to take, are summarised in the ‘Practical Information’ and ‘During the hike’ sections.
(Direction) Several walkers suggest doing this walk in the opposite direction, which is of course possible, but early risers will then miss out on the sunrise over the Obious and the other Isère peaks of the Dévouluy.
(Start/Finish) From the car park, follow the path climbing up the north-eastern shoulder of the Serre (signpost indicating the climbing site). After 300 m, look out for a cairn on a path branching off to the right.
(1) Leave the path heading up towards the climbing site and take the one heading eastwards along the hillside, marked by the cairn. The route remains level before crossing a ravine. It then climbs gradually before turning north, following the slope upwards and veering back westwards. It joins the edge of the western cliff face of the Gicon at IGN elevation 1659.
From there, follow the track that climbs northwards, as close as possible to the western cliff face of the Gicon, until you come within sight of a huge, semi-detached rock on the western flank of the cliff: the Piéroux.
(2) A secondary path allows you to make a round trip to the northern promontory of the Piéroux. After admiring the view, return to the main route and continue climbing northwards along the cliff.
⚠️ It is easy to lose the path; if this happens, always head westwards back towards the cliff to rejoin the main path.
This will take you to the cairn-marked summit of the Gicon (incorrectly spelled ‘Gigon’ by the IGN since 1986, despite repeated requests for correction from local residents and walkers).
(3) From the summit, follow the edge of the northern cliff face eastwards until you reach a gap allowing you to descend onto the northern shoulder of the Gicon.
(4) Descend carefully – particularly if the ground is wet – down this shoulder and follow it to the rocky ledge below.
(5) Several gullies above the scree descend from this outcrop due east, towards the Cabane de l’Aup, which is clearly visible below. Choose one of them and descend off-track towards the scree. Follow the loose scree eastwards until you reach the Cabane de l’Aup.
(6) Head south-southeast onto the grassy track suitable for vehicles, which descends alongside the Queyras torrent. This track becomes a forestry track at the 1492 mark.
(7) Continue south on this track, which then turns west to reach the starting point (S/E)
I enjoyed the hike, with good descriptions and beautiful scenery, except that a fairly dense fog at the summit disrupted us. Thank you for the GPS tracking 😊 otherwise we would have turned back. To be done again in good weather.
