Pont du Châtelet (Saint-Paul-sur-Ubaye) walks

This fifteenth stage crosses the Escreins massif (not to be confused with the Écrins massif) and, via the Ubaye valley, enters the Chambeyron valley. From the Refuge de la Cime, the route—off the GR®5—crosses the Torrent du Mélezet valley and climbs up the Pré Girardin valley via the ski runs; then, on the plateau, it skirts the rocky ridge overlooking Lac Miroir, reaches the lake and rejoins the GR®5. The route climbs up the valley between the shoulder of the Pic des Heuvières and the Crête de Coste Belle, passing the small pass of Sainte-Anne and then the lake of the same name before reaching the Col Girardin. It descends towards a basin, where the Torrent des Séchoirs has its source, and follows it. Clinging to the side of a steep slope, it joins the D25 road in the upper Ubaye valley and continues downstream, alternating between the road and paths close to the river. It leaves the D25 for the Fouillouse road, passes the vertiginous Pont du Châtelet, a tunnel and, via a path, reaches the hamlet of Fouillouse.
