Park in the car park on the left, just below the Col de Pailhères, after the last houses.
(S/E) From there, walk 150 m up the road towards the pass, then take the track that heads south on the right in the bend (red and whiteGR®7Bmarkings, which replace theGRP® Tour de Pays du Donezan). Continue to a three-way junction, just after the altitude 2015.
(1) At this fork, leave the track that branches off to the right and leave theGR®7B, which heads due south.
Take the path between the two that climbs south-west towards the Mounégou ridge. Continue along this ridge to the summit of Pic de Tarbésou, which is visible from the start and can be reached in 45 to 60 minutes.
(2) Join the ridge path (Sarrat des Escales), which is clearly visible from the summit, heading south. The start of this path is not necessarily well marked at the summit, and be careful of the slope at the beginning. Continue for about 15 minutes along this ridge, which heads south-west, until you reach a fork that branches off completely to the left, heading north-east. It is not very visible from the ridge path, but it is clearly visible from Tarbésou and marked on the map (altitude 2171).
(3) At this fork, leave the ridge line and turn sharply left, initially following the contour line. Soon, the unmarked path becomes more clearly marked and loops around the north side of a rock formation and an area of scree, then descends southwards towards the Étang Noir. The path then disappears into a wetland area and is no longer clearly marked, but you can continue on sight towards the lake, which you will reach in about ten minutes.
(4) At the edge of the lake, climb up to the left and quickly join theGR®7B.
(5) Follow theGR®7B(red and white markings) on the left and climb up to the Col de la Coumeille de l'Ours.
(6) At the pass, continue on theGR®7Bheading north until you reach the fork in the path.
(1) Continue to the right, still on theGR® 7B, and join the (S/E).
