Park your car in the car park at Lac de Saint-Apollinaire.
(S/E) From the car park, walk along the lake towards the beach.
(1) Head due north towards the forest. Take the small path that climbs behind the fountain or the path slightly further to the right.
The path climbs steeply up to the forest road (GR®50-RouteForestière de Joubelle).
(2) From there, take the small path leading uphill opposite, behind the signpost, at elevation 1620.
(3) A hundred metres further on, you’ll come to the Joubelle Forest House, where there’s a fountain with very cold water (be careful, it’s glacier water and can cause stomach ache).
Continue to the left of the house; a sign indicates “Joubelle-Aiguilles de Chabrières Trail at 3 o’clock”. This is the route you’ll need to take to reach the top. The path winds through the forest and emerges at a cairn on the path coming from Réallon.
(4) From the path, continue to the left (Blue Circle, if it’s still there), still climbing, then follow the ridge to the chalet where the Réallon chairlift arrives.
(5) After stopping near the chalet for a quick snack, go to the left of the chalet, towards the viewing platform and then towards the orientation table.
(6) Please note: after the orientation table, the path is very steep and entirely over rocky terrain. You will need to use your hands to help you along.
After giving your legs and hands a good workout, you will reach the Pic de Chabrières.
(7) From the peak, look down to see the Oucane in front of you and the Aiguilles a little higher up.
(8) From the Aiguilles, you can return via the Oucane, but you will find yourself on the other side of the mountain at the Réallon station. In this case, it would be best to have parked another vehicle there to reach Saint-Apollinaire or, if you’re feeling brave, head back up through the forest via the Joubelle forest road to go round the massif and find yourself at the 1620m mark mentioned above.
(2) The return route described will therefore follow the same path as the ascent to Lac de Saint-Apollinaire (S/E).
