Departure from the Guisane valley for Pelvoux
MONETIER - EYCHAUDA LAKE - PELVOUX
You can leave your vehicle along the Guisane in the car park at the start of the GR54. This is a free, unguarded car park. If you choose to arrive the day before, you can stay at the gîte "le Flourou", which is just opposite this car park. Please note that this is a real stage, so you'll need to leave early (9am maximum). Today we leave the Guisane valley for Pelvoux. Leaving Monêtier-les-Bains, it's a long morning climb up the Tabac valley to the steep Col des Grangettes (2684m). You'll have a bird's-eye view of Lac de l'Eychauda, which freezes over late in the season. Descend into the magnificent Eychauda valley to reach the Vallon Chambran.
7 hours walk / Altitude difference +1100m -800m

BETWEEN AYGUES - COL DE L'AUP SAINT MARTIN - PRÉ DE LA CHAUMETTE
For this stage, we advise you to take the regular shuttle bus (for a fee of €10, booked with your accommodation provider, it will save you a good 2 hours' walk).
Start this stage with a light kit, as your bags cannot be transported to the Pré de la Chaumette hut.
A long, gently sloping climb up the valley (you can book the shuttle bus to take you to the bottom of the valley (6km); ask your accommodation for details). Once you are out in the mountain pastures, you can see the pass in the distance behind several rocky locks, which you climb for a long time. 
The final climb is a little steeper, in black schist, a slightly austere atmosphere that spices up the end of the ascent. We pass the Col de l'Aup Martin (2761m) and then the Pas de la Cavale. A quick descent to the Pré de la Chaumette refuge.
