Crossing the slopes of the Provencal-Castello group,
from which you have an excellent view of the Stroppia waterfalls, you will reach the Grange Collet parking lot.
Here you need to leave the pavement to follow the ancient cobbled mule track on foot
until you reach a wide valley where you can rest on the shore of a little lake.
Last sprint towards the pass, that divides France from Italy.
Proceeding on the right, among rocks and debrises, you will reach the suggestive lakes of Roure.
