On the RM 64, the Col de la Bonette road, park at the Camp des Fourches car park.
(S/E) From the car park, take the path on the right towards the Col des Fourches, which you will reach very quickly.
(1) The Col des Fourches already offers a splendid panorama of the Salso Moreno. Descend towards the valley following the GR®5.
When you reach a stream, the Ravin de la Tour, cross with caution. The passage is steep and slippery.
Climb up the other side of the stream, pass an unmanned refuge and then cross the stream coming from the Vallon de la Gipière.
Shortly afterwards, you will arrive at an intersection at marker 37.
(2) Climb up to the left, continuing to follow the GR®5 towards Pas de la Cavale.
The climb is gradual and you will see (if you haven't already) many marmots that are not very shy.
After crossing a small stream (at the springs indicated on the IGN map), the trail turns right and then left at a large sinkhole at an altitude of 2344 m.
(3) Leave the marked trail on the right and carefully go around this sinkhole. Do not hesitate to go higher up to avoid the very steep and slippery sections. Immediately afterwards, reach the upper lake and descend along the lakes. Atthe third (the largest), turn left of the outlet to find a faint trail at a cairn overlooking the valley.
Descend to the edge of the Combe du Graillon to join thePR® coming from the Col de Pourriac, which passes through the bottom of the valley.
(4) Follow the marked trail to the right. After a short climb and passing by another sinkhole, you will reach the intersection at marker 37.
(2) Continue straight ahead along the same path you took on the way up towards the Col des Fourches.
(1) From the pass, you can make a short detour to Mont des Fourches on the left for a beautiful view of the Tinée Valley.
Otherwise, continue to the right to return to the starting point at the Camp des Fourches car park (S/E).
You are in the Mercantour National Park, where there are regulations to be observed, with fines of up to €1,500 for non-compliance. See practical information.
