Advanced Trekking Aneto

The route begins in the forested valley near Plan de Senarta, and climbs steadily into high mountain terrain. Following the torrent, the landscape changes from pine woods to open alpine slopes with ever-wider views towards Pico de Paderna and Tuca Blanca de Paderna. The stage is consistently uphill, gaining roughly 900 m of elevation and giving an early taste of the rugged scenery surrounding the Maladeta massif.

The path first follows tracks and clear trails beside the Barranco de Alba, with the rocky summit of Turonet d’Alba rising above the valley. Higher up, the route leaves the wider track to take a steeper mountain path that zigzags through meadows and boulder fields. As height is gained, the panorama opens towards Corona de Remuñe and the distant glaciers on Aneto.

The final climb traverses a stony spur before the white building of the refuge appears. A short traverse leads to the terrace, where the views over the Benasque valley and surrounding peaks reward the effort. Inside, the hut offers bunks, hot meals and a convivial atmosphere, making it an ideal base for the following high-mountain stages.

This high-level crossing links two alpine refuges over rough, remote ground. The itinerary climbs towards the ridges above the hut before dropping again to the basin of the Llauset lakes. With about 1,040 m of ascent and 770 m of descent, it is a demanding day in serious terrain, rewarded by continuous views of the Maladeta and Barrancs groups.

From the hut the trail climbs steeply on cairned paths towards the slopes of Tuca de la Renclusa, weaving between rocks and small tarns. Once on the upper benches, the route continues beneath the serrated crest that includes Tuca de Barrancs and the distant Pico Maldito. The path can be faint and crosses boulder fields where progress is slower and careful footwork is essential.

The traverse then turns south towards the high plateau dotted with the Ibones de Anglios. After skirting these lakes, a final undulating section leads to the outlet of the Estany de Llauset, with Cap de Llauset rising above. A short, steep climb on a good path brings the day to an end at the modern lakeside refuge, well equipped for a restorative evening.

The last section completes the circuit with a long descent from the high basin of Llauset back to the forests of the Benasque valley. The trail first gains a modest 330 m before losing around 1,370 m to reach the valley floor. The scenery changes from stark, rocky peaks around Cap de Llauset to grassy slopes, mixed woodland and finally the riverside tracks of the lower Ésera.

From the refuge, the route briefly climbs towards the shoulder below Tuca de Anglios, contouring above the deep blue Estany de Llauset. It then swings west into a long valley, descending on a mountain path that alternates between grassy terraces and rocky steps. Peaks such as Pico de Cregüeña and Tuca dels Ixfarts line the horizon while small streams and tarns accompany the descent.

Lower down, the path softens into forest tracks and easier trails beside the river, passing occasional clearings with views back to the high summits. The final kilometres are almost level as they approach the open meadows and facilities of Plan de Senarta. Accommodation is reached on wide tracks, offering a gentle finish and convenient access to transport, campsites or nearby lodgings for a comfortable night after the trek.
