Departure from the Col de Gleize car park.
(S/E) From the car park, take the path to the left of the small house, which is signposted towards Pic de Gleize. Follow the yellow markings and, at the first fork, continue straight ahead following the yellow markings. The path climbs through the pine trees to reach the mountain pastures on a flat area.
(1) At the Forest d'Amoutty sign, turn right towards Laye station and Les pins de l'Aiguille. This path crosses a cattle trough and descends gently into the forest. It crosses the ski slopes twice, then arrives at the Les Pins de l'Aiguille sign.
(2) Continue straight ahead towards Laye Station and Galembert. Just before the Galembert sign, a small spring feeds a pretty little fountain.
(3) At the Galembert crossroads, take the path that climbs to the left towards Coste Belle. You will see dark green markings at the start, but these quickly give way to yellow markings. The path climbs below the Pic de l'Aiguille along the mountainside to reach the ridge. You need to be careful in some places.
(4) Once on the ridge, ignore the markings that lead to the right and head left along the ridges. From here, there are no more markings or paths, so you will have to walk by sight!
Overall, you need to reach the path that is at the same level as the ridge you are on, in the rocky ridge between Pic de l'Aiguille and Pic de Gleize (on the left).
Walk along the ridges for a while, then pass above the last fir trees and continue along the mountainside until you come to an impassable gully above a small stream.
(5) At this point, you need to descend vertically down this small ridge for about a hundred metres to reach the bottom of the stream. Cross it and continue left along the mountainside, always heading for the rocky ridge. In some places, you may find goat or chamois tracks, which will help you on your way. When you come to a "sub-pass" in the mountain pasture, climb back up to find the path above.
This path is halfway between Pic de l'Aiguille and Pic de Gleize.
(6) Once you reach the path, turn left and climb straight up towards the rocky ridge. The path will pass through the ridge via a tricky passage, then climb up towards the unnamed pass.
(7) Once you reach the ridges, a small wooden post marks the crossroads (with no further indications). Turn left onto the path to approach Pic de l'Aiguille and enjoy views of the Champsaur valley.
(8) When the path becomes too dangerous, retrace your steps to find the junction with the wooden post you passed earlier.
(7) From there, continue straight ahead to climb towards Pic de Gleize (yellow markings).
(9) Once at the peak, continue straight ahead on the yellow marked trail (no. 16). Be careful, as a sign warns of the danger of the descent. You must be vigilant and watch your step, but there is no major precipice.
Descend back down to the mountain pastures to find a crossroads.
(10) Take the path on the right that descends, marked in yellow (No. 16).
After a steep descent, the trail arrives at the Forest d'Amoutty junction.
(1) Continue straight downhill towards Col de Gleize to return to the car park (S/E).
