Summary:
Climb to a meadow set amongst high peaks and descend via a series of cascades.

From the parking area by the Rio (river) Cinca, head along a wide stony track, past a trail sign. The track climbs gently away from the river towards the massive peaks of the cirque at the head of Pineta Valley, and waterfalls tumble from huge cliff faces.

After about 20 minutes, the track meets up with the river and you cross the first bridge. Here there is a wonderful view of the river rushing through water-carved rocks down into the wooded valley framed by high mountain peaks. Shortly after, pass a narrower path on the left that climbs up to Cascada del Cinca and Lago de Marbore. You continue ahead on the wide track signed to Llanos de la Larri.

The trail moves away from the river again and climbs a little more steeply through trees for 15 minutes. Shortly before the second bridge, your return route, the Camino de la Cascadas, descends to the right. For now continue ahead, over the bridge past a powerful cascade rushing through rust-colored carved rocks.

10 minutes further on the gradient lessens once more to a gentle climb. It is just a few more minutes before you reach Llanos (literally flat ground) de la Larri (‘Plans de la Larri’ on the National Park topograhic map), a wide meadow surrounded by high cliffs. Behind you to your left, Monte Perdido rises majestically. Take your time to wander through the meadow towards the cliffs ahead.

To descend to the valley floor, follow the same route back to the bridge, where you turn left to descend via the Camino de la Cascadas. As the name suggests, the trail follows the course of the waterfall as it winds its way down the wooded hillside. The trail is pretty steep, and can be muddy and slippery in places, particularly after rain.

Emerge into the valley and follow the river along a wide stony path. Cross a bridge (where there is a fine view of the Circo de Pineta, the ring of peaks at the head of the valley) and continue towards the car park. The river is now to your left. Pass the Parador, which is on the opposite bank, and soon the car park comes into view.

Directions: From France, the most convenient border crossing is through the Bielsa Tunnel on the D929, which becomes the 138 once inside Spain. Turn off the 138 into the town of Bielsa, 10 km south of the tunnel and 30 km north of Ainsa. After 0.5 km, before you enter the town center, turn right along the signed road that runs for 14 km through the Pineta Valley.

Trailhead: Car park on the left, about 0.5 km before the end of the road.
