On foot (GR54 ...) : you arrive by the fountain, in front of the church. Turn left via a narrow lane (prohibited) for 300m to the gîte
 
By car : if you arrive from the church, do not take the narrow lane and the no-sign as some GPS may indicate ... but take "les Vaudois" below the store.
The easiest, when arriving from Argentière or Briançon: after the 2 successive speed bumps from Vallouise la Casse (Ecrins sport store etc ...) turn left towards Puy Saint Vincent / Maison du Parc. At the end of the straight line, turn right, cross a small bridge and about 600m later, turn left towards Villard, Puy Aillaud. The gîte is just after the hairpin. 

See the 2 plans below. 

Parking : we have about 5 or 6 places to park. If it is full or in winter (during or just after a snowfall, you can drop off your belongings and park in the Gravière car park (after the church bridge on the left) or at the Gérendoine bridge.
