2. The 4 valleys circuit - Stura - Maira - Haute Tinée - Ubaye - Stage 2

From the Gardetta refuge, head up the track which can be used by vehicles, using a few narrow paths as shortcuts, to reach Passo della Gardetta à 2440 metres. From there, head downhill along the path with GTA/S8 markers until you reach the bottom of the valley, first passing close to the remains of some military installations. Once you reach a track located a few metres below an oratory (Prato Ciolero), turn left and after two bends in the track you will cross the mountain stream at an altitude of 1995 metres, close to a ruined building and a place selling cheese. Head up the path which starts to the right of the northernmost building, going uphill along some hairpin bends. Go past a wooden oratory and stay on the path, bearing right. Further up, stay on the right when you reach the path with S27/S10 markers (altitude of 2018 metres). Further up still, go straight on – do not take the S27 path for S27 du Colle Vittorio. Pass Passo Dell Escalon which is not very clearly defined between the boulders at 2450 metres. Stay on the S10 path – do not take the S20 path on the right or the path on the left of the Due Valli bivouac. Reach the Col de la Scaletta marker and then continue along the flat path below the ruins of some military buildings and you will quickly reach a secondary summit with a panoramic view over the Roburent lakes. Head downhill along a series of hairpin bends then bear right, avoiding the narrow paths which head to the shores of the lakes to continue along the mountain face, reaching Col de Roburent at 2502 metres after a few uphill hairpin bends. Here, begin the descent towards the north-east of the col along a very good path with GR Pays du Tour du Chambeyron markers and you will arrive close to the shores of Lac de l'Oronaye 2411m. Walk alongside the lake and follow the valley and the Oronaye mountain stream to reach the road for Col de Larche on the left gauche 1996m.
