Park in the large, well-equipped car park on the edge of the D205t, between the Refuge and Col Agnel.
(S/E) At the bottom of the car park, take the well-protected path. Follow the gentle, steady climb to reach the Col Agnel.
(1) Turn left and follow the road downhill for about 100 metres. Cross the road at the new car park and take the path opposite that leads uphill. Continue along this path, almost on the French-Italian border, until you reach a four-way crossroads. There is a circular stone shelter here.
(2) Continue straight ahead and begin a short descent followed by an easy climb to reach the pass, the Brèche de la Ruine.
(3) Now begin a new, short descent, but be careful as the descent between the rocks is very tricky and requires great vigilance. Then continue on an easy climb to reach Lac d'Asti.
(4) Return by the same route, but in the opposite direction, to the Brèche de la Ruine. Shortly after the pass, turn right, continue the descent, and arrive at a large grassy clearing.
(5) Be careful, as the path disappears here. Continue to the left to pass over a small rocky outcrop, and you will find a well-marked path at the end of this passage.
(6) Take it to the left for a short climb to reach Col Vieux.
(7) Take the GR®58 Tour du Queyras trail on the left, marked in white and red. Follow this trail, which has been re-routed to protect a sensitive area. Continue downhill to reach the crossroads at the car park, where you will find a signpost.
(8) Turn left to easily reach the D205t car park (S/E).
