Take the third exit following the signs for Gimillan. Drive up the communal road for about 3 kilometres passing the village of Montroz and, once in Gimillan, at the crossroads keep to the right and continue for about 200 metres until you come to a large free car park 🅿️ located on the right-hand side of the road.

Description

0h00' Climb up the wide path between terraced pastures until you come to the little farm road leading to Plan de Cretetta, which you should follow as far as the signpost. Along this first section of the walk, you can appreciate interesting views of the glaciers at the head of Valnontey, the Lillaz plain and, turning around, the village of Gimillan and the Pousset peak.

0h10' At the marker take the path to the right that goes almost level above Tarabouc (1831m) and the characteristic chapel dedicated to Saint-Bernard. Past the power line, the trail veers slightly to the left and enters the Vallon de Grauson. After skirting a ruin, you will come to a votive shrine and a new marker indicating the junction with path coming from Montroz (1895m).

0h20' Continue straight on for a short distance until you come to the  fork for the variant to Tchezeu (1915m), which should be ignored.

0h25' The path begins to descend the eastern slope of the Truc Cretetta halfway down the valley and leads to the bottom of the valley where a small wooden bridge (1889m) allows you to cross the Torrent de Grauson near Encloseur.

0h40' After crossing the bridge, you will come to the fork between path and path to Colonna (1903m). Turn left and continue up the pastureland, keeping to the orographic left of the valley on the easy path that soon reaches the end of the Tchezeu variant (1967m). 

0h50' Crossing a short strip of larch (Larix decidua), you will come to the Pila pastureland, which remains below on the left. Disregard the signs for the Cascate di Pila waterfalls, marker , and continue straight ahead, following the obvious path around the northern ridge of Mont Creya. A few bends allow you to gain height and lead to a peculiar cairn composed of stacked wooden logs. Cross another larch grove by keeping halfway up the steep slope, leaving the Torrent de Grauson gorge to the left. Past the larch forest, the Crouzet farmstead appears on the left and, shortly afterwards, the pleasant plateau of Grauson dèsot is reached. On reaching the cross, which remains on the left, you will come to the junction for path that leads to Lake Money and Mont Creya: continue on path along a short downhill stretch on the lovely green plateau where it joins path , which is the winter access route to the valley and the cottages of Grauson dèsot (2273m).

1h30' Continue by entering a small narrow passage over the stream, which is crossed shortly afterwards by a small wooden bridge. Once through the narrows, continue along the grassy valley until you reach a new fork (2391m).

Walk alongside the stream to reach a fork signposted by a post (2399m) and take the track to the right, which cuts across the slope and arrives immediately at the Pralognan alp (2416m); the track now continues along the side of the mountain, rising slightly and continuing halfway up the valley without an excessive gradient. At an altitude of 2,515m, the trail passes the Eveilleres chalets and, approaching the crags towards the bottom of the valley, bends slightly to the right to cross a stream on a small bridge and then climbs a few grassy rises. Passing between some of these, the trail arrives at the lowest and largest of the Dorèire lakes, while to reach the other three, which are much smaller, it is necessary to climb up the trail for a hundred metres in altitude, finding them at 2,774m, 2,829m and 2,844m respectively.
