Just before Casterino village (altitude 1543m), start out from balise 367.
This is a 4×4 track so follow the track and do not deviate. It climbs steeply but it’s an easy walk. For about 1 1/2 hours the walk is shaded by pines.
Then the track passes through a wide open area of meadows including a dairy farm.
And then 1/2 hour later you reach the top (balise 370; 2040m altitude) with views over the surrounding peaks and down to Casterino. There are also some Army bunkers dating from WWII as this is close to the Italian frontier. For a picnic place I went about 500m further following the road to the Peirefique lakes and climbed a small mound. The track meets a road and there’s a small parking area.
It took me two hours to climb and about 1 1/2 hours to descend both at a very slow speed!
