Coming from Gap, take the D944 then follow the D13 straight ahead to wooden roof tile. Pass Le Château d'Ancelle and continue to Ancelle, following the D13. At an intersection at the bottom of the village of Ancelle, turn left, cross the bridge over the Rouanne, then turn right and, at the next bend, turn right again onto the small tarmac road which then becomes a wide track with several fords.
Continue to the end of the Vallée de Rouanne Haute. The route is easily accessible by normal car. Park in the car park.
(S/E) Go to the footbridge over the Rouanne below the car park. Cross it and continue for a few hundred metres.
(1) Take the path that branches off to the left. Begin the ascent to an intersection.
(2) At the intersection of two paths, take the upper path on the right. The two paths rejoin a little further on. Continue to the intersection of these paths. The path coming from below continues towards the Balcons de Rouanne.
(3) Turn sharply right until the next intersection.
(4) The path on the right leads directly to the Col de la Pourrachiere. Turn left and follow the path along the ridge below Pointe de Fleurendon and above Clot des Naïs to reach the Col Chorges. At the bottom of the valley, you can see a summer farm. From the pass, there is a magnificent view of Lake Serre Ponçon and the Mercantour.
(5) Turn right and follow the path that leads to Piolit. The summit offers a 360° view.
(6) From the summit, descend about 200 to 330 metres (see photo with caption). Turn left to descend into the mountain pastures until you reach a path that is difficult to see. Continue to the Col de la Pourrachière.
As the path was covered in snow, we sometimes deviated from it, taking detours to avoid the snowfields on the Bonaparré ridges, which made the hike particularly tricky and, above all, very unstable. This was especially true as this entire section of the route is on a slope.
(7) At the Pourrachière pass, turn left and continue downhill, crossing the mountain pastures, passing a spring and the Courou torrent, and continuing through the forest until you reach an intersection.
(8) Turn right and continue down the forest path.
(9) Take the wide forest track, which branches off to the right well above the stream and ravine. This path is not shown on the IGN map, which shows it running alongside the stream below. Continue downhill and cross the bridge over the Rouanne again to reach the car park (S/E).
Great walk, second part not marked at the beginning
