Start: Leaving the Bielsa Tunnel, head for Bielsa. After the Parzan tunnel, follow the signs for Bielsa - Valle de Pineta. Follow the road to the Pineta Valley car park.
(S/E) Reach the bottom of the car park and continue North-West towards the Larri waterfall. Signs at each intersection point the way to the waterfall.
(1) Cross the Cinca river on a small footbridge and continue Westwards.
(2) Take the path heading North. From this point on, the path begins to climb via wooden or stone steps. Along the way, you can admire the Larri river.
(3) When you reach the tarmac road, turn right to reach the bridge, where you can admire the Larri waterfall.
(4) After admiring the waterfall, continue along the asphalt road. At one point, you'll have to go over a low wall if the gate isn't open, then continue to follow the asphalt road (there are footpaths cutting across the asphalt road, so it doesn't matter whether you take the road or the footpaths, they all lead to the refuge).
(5) At this junction, level with the refuge, you enter the Lianos de Larri, where you can admire the Pineta cirque and the superb Mont Perdu. Continue straight on towards the bottom of this cirque to reach a waterfall.
(6) From this waterfall, return along the same path to an intersection between the tarmac road and a path (GR®11) heading South.
(7) Take the GR®11 Southwards. It takes you back down through the forest to the starting car park.
(8) Back on a tarmac road, walk South along it to reach the Pineta valley car park (S/E).
