Access to the mountain is easier from Spain than from France. The route starts near the village of Torla, Aragon, at the Ordesa Valley and ascends the Cirque de Soaso towards the Refuge of Góriz before the stiff climb to the summit. It is a dangerous climb with snow.
Monte Perdido is the centre-piece of the Spanish Ordesa y Monte Perdido National Park which was established in 1918 with just 21 square kilometres of land. The park has grown significantly to 156 square kilometres and incorporates the whole of the Añisclo Canyon. There are more than 1500 species of flowers, 171 species of birds, 32 different mammals and 8 types of reptile in the Ordesa. Most magnificent of all is the lammergeier (bearded vulture) with a 3 metre wingspan. The Pyrenees is one of the few places in Europe where these birds can be seen.
