FATMAP difficulty grade
From the Col de Portus (1736 m), which can be reached by car by a bad track or by foot from Evol, head towards the Gorg Nègre (Lake Evol) by a pastoral track, to a shed, then a path which climbs on the left bank of the valley immediately opposite.
From the lake climb follow the signs towards the NNW towards the refuge of Nohède / de la perdrix / de perdiu.
From the refuge, take towards the NNW to Clot Rodon and Roc Nègre (2459 m).
We then follow the ridge towards the W, with a short section a little steep, before reaching the top slope.
Return by the same route. *Variants* From the lake, it is also possible to head SW towards point 2273, marked on the map, to push a visit to the Pelade peak (2370 m).
We then return by a long flat to the hut of the Partridge and follow the route that leads to the top of the Madres. On the way back, it is possible to continue full E and NE before descending to Gorg Estelat (Lake Nohèdes).
From the lake we find the old Jujols trail which takes us back to the Portus pass.<br/><br/>_This Adventure has been shared under the [Creative Commons Share Alike](https://creativecommons.org/licenses/by-sa/2.5/) licence._
