Park in the Dormillouse car park in the Freissinières valley.
(S) Begin the climb towards the village of Dormillouse. The path rises quickly in short hairpin bends to reach a crossroads.
(1). Take the yellow-marked trail on the left where a sign indicates Lac de Fangeas. Stay on this trail, which gently leads to the lake.
(2). Walk along the lake and cross the footbridge over the stream that feeds the lake.
Continue climbing; the markings become white but are very spaced out. Look carefully for them to pass through the rocky ridge (the passage is completely safe).
You will then come out onto the mountain pasture and, after a long traverse, reach the Col des Terres Blanches.
(3) Begin the long descent and reach the Col des Tourettes crossroads.
(4) Continue the descent to reach the Drac Noir and the Saut du Laire.
(5) Take the wide path on the right and continue the descent to reach a wide track.
Take it on the right and reach Prapic and its lodge (E).
! On Sunday morning, we set off at 7:30 a.m. to do the same hike again but in the opposite direction, which seemed much more accessible than the second part, which, after talking to the shepherd and a few walkers, seemed more physically demanding and longer.
