(S) From the Loge refuge, follow the GR® (red and white) towards Crêt de la Neige. A wide, ascending path quickly enters the forest, crosses the ‘Les Asters’ red-marked downhill ski run and reaches the Brillonne d’en Haut junction.
(1) The path climbs to the left into a pretty valley, runs past a ruin on the right, briefly dives back into the forest and then emerges into the Combe des Voyettes. It goes round the water reservoir before a fairly steep climb up to Les Brûlats.
(2) The route heads right, follows the contour line, climbs along a small cirque and reaches a first viewpoint, “Sous le Crêt” (1,683 m).
(3) Keep to the right on the GR®. The path becomes undulating and winding, dotted with sharp limestone pavements and exposed boulders. Magnificent canyons lined with mountain pines come into view before reaching the highest point of the stage: the Crêt de la Neige (1,720 m).
(4) Continue to the “Sur les Brûlats” junction.
(5) Continue straight on the GR®; the path descends into the hollow of a valley near the ruins of an old mountain village, then climbs back up the ridge to the second highest peak of the stage: the Reculet (1,718 m).
(6) Turn right to the other side; the path becomes a dirt track and skirts a vast cirque where the Narderans arches are visible in the distance. The ridge narrows and runs alongside the magnificent Roche Franche to the Grotte de la Marie du Jura (caution: the passage to the other side is neither signposted nor secured; you must stay on the official path.)
(7) At the “Sur la Chaz” crossroads, continue straight ahead and descend to the Polvette mountain pasture. Follow the ridge then head down into the forest along a steep section before coming to a pretty valley: this is the Passage du Gralet. Reach the Gralet refuge.
(8) Go round the refuge and stay on the GR® trail, which heads into the forest and follows the ridge through dense, lush greenery. The undulating terrain makes for easy going before you emerge into the Poutouille valley, where you’ll find the refuge of the same name (E).
