The starting point is at Étang de Bethmale. There is a large car park where you can park before the bridge, as soon as you leave the D17. You can also park after the bridge and after the forest house.
(S/E) Take the forest track (Mount Ner track) that passes in front of the house and stay on it.
(1) After a first 90-degree right turn, the track begins to climb gently through the forest. Take a look to your right for a magnificent view of the snow-capped hills. After 2 km, you will arrive at a clearing and the track will make a sharp left turn.
(2) Continue for another 50 metres and you will see a path on your left that runs through the forest in a south-south-westerly direction. Follow this path for 200 metres and you will come back to a barn, on the forest track you left 5 minutes ago.
(3) Continue in the same direction, south-southwest, for about 500 metres to climb the grassy ridge.
During your ascent, you will pass a first ruined barn halfway up the hill, then a second one in much better condition (point 1383).
After this short effort, you will once again find yourself on the Mount Ner trail, but this little shortcut saves you from having to take the long circular route through Cadus Forest, which is of no interest.
(4) Turn right (west) and stay on this track until you reach your destination.
(5) After the barns at Mont Noir, there is a barrier to pass through. The track continues through a magnificent fir forest before emerging at the Cabane de Campuls cirque.
(6) From the Cabane de Campuls, return via the same route (S/E).
