From the car park return to the RD285.
Cross and follow the road to the right, passing the small modern chapel on the left.
Leave Chemin Capdebarthe on the left and behind the house on the bend, take a wide grassy path which rises on the left (prohibited to vehicles). Path in stony and wet undergrowth.
After a good climb, arrive at the Bonnemaison farm on the left (Beware of dogs!).
Continue opposite on the path which rises gently in the wood for 1.3 km then in the open, with a clear view of the foothills and the Pyrenees.
