You can park your car on the main car park (in front of the Post Office and the Gendarmerie).
When you leave the car park, turn left and go down on the road D39 for about 200 meters. In the hairpin bend turn on the left on the way to Saint André de Najac and take the path on the right.
Cross the Vernhe stream and go up on the cobbled path. Stay on the left to continue on the steep path. At the wide grassy path turn right and continue to the crossroads.
