From Cauterets take the road to Pont d'Espagne. (Parking paying from April. 6 Euros two days). From the parking take the road to de telecabins and then take to the left the route to Gaube lake (50'). Continue by the right side of the lake (RISK OF AVALANCHE!!!) and reach Oulettes the Gaube refuge (CAF) 2160 mts. Total: 2h 30'/ 3h 30' (depends snow condition).
From Oulettes go to the seracs under the north face of Grand Vignemale and by the left side reach the crevase (1h30'). Go up the crevase looking for the easiest part. Continue the couloir and in the middle part, when we passed the "Y"'s bifourcation we have the first complications. 10 mts on ice (75º). Continue about another 200 mts to reach the final icefall (R on the left with 3 Universals emplaced). Now, 40-50 mts of 80º-85º give us to the Ossoue gletcher.
NOTE: This is a description of the route in good conditions. Maybe the last icefall could be more difficult.
ropes 60m, two piolets, 4-6 ice screws, Helmet!!!!!!
