The route starts from the Camps des Fourches car park on the road leading up to the Col de la Bonnette from the Tinée valley.
(S/E) From the car park, take the path overlooking the road which heads east towards the Col des Fourches.
(1) From the Col des Fourches (marker 41), descend into the valley following the GR® 5 after taking in the view of the magnificent Salso Moreno cirque. Ford the first stream and continue along the path, passing a shepherd’s hut. Cross a second stream to reach a junction at marker 37.
(2) Take the path branching off to the left, heading due north towards the Pas de la Cavale.
(3) Give a wide berth to a large sinkhole by leaving the path to the right towards the first of the Lacs d’Agnel that you can see. Walk along the right-hand side of these lakes, then cross the small spillway of the last lake to follow a barely visible track marked by a few cairns. Once at the foot of the ridge, cross the Ruisseau de la Combe du Graillon to join the GR® 52.
(4) Turn left to climb towards the Col de Pouriac.
(5) After skirting a ravine with ochre-coloured rocks, leave the path and head towards an unnamed lake visible on the right. Go round the lake on the left and climb gently off-trail towards the south-east to discover other small lakes.
(6) Look for a spot where the slope levels out towards the south to begin the descent, still following your instincts and off the track, into the Combe de Gorge Grosse heading south-west. After a short, slightly steep but unchallenging section, you’ll reach a virtually flat, grassy mountain pasture. Continue south-south-west, keeping a rocky outcrop on your left. Shortly after passing a partially ruined shepherd’s hut on the left, cross a small torrent and climb gently up the opposite slope. Cross another torrent with eroded banks and continue southwards for a few dozen metres.
(7) Turn right towards the west onto the path coming from the Lacs de Morgon and head for the junction at marker 37.
(2) Head straight ahead and follow the path in the opposite direction to the way out to return to the starting point at the Camp des Fourches car park (S/E).
