(3) Return by the same route to the previous crossroads.
(2) Continue straight ahead, passing Tuc de Tucol. Begin another short descent to reach Cap de Mourens.
(4) Continue straight ahead on theGRP®, follow the slightly uphill path before starting the descent via the Cap des Teches ridges leading to Tuc de Haurades.
(5) Leave theGRP® here and turn right onto the yellow-markedPR ®. Arrive at the Cabane de Roque Pi.
