(S/E) From the Ambin refuge, head up the valley towards Lac d’Ambin.
(1) Follow the Ambin stream.
(2) You can avoid going via the lake, but the time saved is minimal and this short detour is well worth it. From the lake, you reach the Col de l’Agnel via easy scree, but the path is very poorly marked and even non-existent in places.
(3) From there, there’s a lovely view over the Italian Val di Suza, and the well-marked path leads straight to the Refuge Vaccarone
(4) You can take a short detour via Lago dell’Agnello.
A narrow, very steep path descends straight down through the rocky outcrops, below the refuge. You look out over the Clapier lakes, near which you can stop for a bite to eat. From there, you reach the Col Clapier.
(5) Descend to Lac de Savine, quite easily, along the beautiful Savine torrent.
(6) At the ruins of the Chalets de Savine, always take the paths leading down to the left, as far as the Fesse du Haut, and you’ll then reach Le Planey (E).
If you haven’t been able to park a second car here, there’s a good path leading to Saint-Pierre d’Extravache.
