Go to Moulin-Vieux in the commune of La Morte, either from La Mure via Lavaldens or from the Alpe du Grand Serre resort. From there, it is best to have a map as the road leading to the start of the hike is not signposted (nothing is signposted, in fact). Park in the car park at the end of the tarmac road
(S/E) Start the hike on the path that continues along this road.
(1) Continue straight ahead at this crossroads on this path, which is half track, half trail (signpost).
(2) First stream crossing, where it's not easy to find the right stones to cross! But you'll get there, even if it means getting your feet a little wet!
Then, the trail begins to climb a little more steeply over small pebbles covered with leaves.
(3) After the footbridge over the Vaunoire stream, continue on the path, which begins to climb again.
(4) As soon as the path reaches the edge of the stream, find a way to cross it and reach the grassy area on the other side. The route continues there, but unfortunately, there are no signs to indicate this! There is no point in continuing too far along the left bank, as you will have to turn back to rejoin the path.
Once you have crossed the stream, take the path, which is barely visible at first, and begin the winding ascent.
(5) Continue straight ahead on the now well-marked path, which climbs quite steeply towards the pass
(6) Arrival at Plancol (according to the IGN) or Plan Col (according to the signposts)!
Admire the view, then turn around and take the path downhill.
Return to the car park (S/E).
