In Benasque's valley, located in the nature reserve of Posets-Maladeta we find three big ranges full of beautiful and high summits of more than 3000 meters; they are the ranges of Maladeta, Posets and Gourg-Blancs/Perdiguero. The range of Maladeta contains the Aneto, which is the highest and more popular peak of all the Pyrenees but the other two ranges also are very frequented specially in summer for containing the highest second mountain (Posets) and one of the most attainable, the Perdiguero, with big view of landscape of other ranges difficult to overcome.
The massif of Perdiguero it's in the border with the French valley of Luchon and it has the entry in Granges d'Astau near of the village of Bagnéres de Luchon. Its ascent from this side it's longest (6h to summit with 2100m of slope) but present a good stage in the Refuge du Portillon (4h from the trailhead) to spend the night the previous day.
In spite of not presenting technical difficulty in summer, its ascent is long, more than 5 hours in its Spanish normal route, as what it must not despise and to have a good physical condition to climb to this mountain. The final section is a characteristic pile of big blocks of granitic stones that needs effort and concentration to climb. A nice remuneration to this effort is the view and the previous visit to Literola's lakes where it crosses the normal route.
As curiosity, the peak Perdiguero is the highest point on the French department of Haute-Garonne (border France-Spain in the summit)
First climb: in 1850 by T.Lézat and J.Redonnet.
The Perdiguero is the highest point of this range but contains a lot of summits:
Secondary summits of Perdiguero: Hito Este (3170m), Hito Oeste (3077m), Tuca de Literola (3095m), Pico Royo (3121m), Punta de Literola (3132m), Aguja de Literola (3028m), Perdigueret (2839m).
For approach to valley of Benasque and to known more about the other ranges of the valley you must see the pages of Posets and Aneto.
No permits required. The Perdiguero is in the Natural Reserve of Posets-Maladeta with your rules. No restriction to access to the trailhead of normal route in the road to Hospital de Benasque (from Hospital it's restricted the circulation of cars in summer and you must take the bus to La Besurta to climb the Aneto).
When To Climb
Summer is the normal epoch: june to september.
