After crossing the Pont des Albrands and just before the junction with the track leading up to La Pousterle, park wherever you can and look out for a bridge below on the left – this is the start of the Sentier des Chardons Bleus.
(S/E) Head downhill and cross the bridge. Follow the path through the woodland until you come out onto a large meadow – this is La Murègne. Look out for the crossroads.
(1) At this junction, ignore the path leading off to the right but carry straight on along the path that crosses the meadow. Continue through the woodland until you emerge into a clearing – this is Boujurian. Walk past the first chalet and carry on to a junction.
(2) Take the path that climbs to the left, walk past some chalets, then continue along the path through the forest and pass through an area of scree caused by winter avalanches. Then, walk through the forest. The path begins to level out and the first thistles appear. This is the entrance to the nature reserve.
(3) At the entrance to the reserve, follow the path to the junction near a footbridge.
(4) Ignore the path that crosses the Torrent du Fournel and leads to the car park; instead, carry on straight ahead. Make sure you stay on the path at all times. Cross the Deslioures Biological Reserve and then follow the path. Enter the woodland. The path continues through the forest, ending in a clearing caused by winter avalanches. This is the Ravin des Trois Queyrons, the end point and turning point.
(5) Return via the same route to the Pont des Albrands car park (S/E).
