The national Park of Ordes e Monte Perdido has a wide variety of ecosystems, with both Atlantic and Mediterranean influences, translating as a rich and diverse flora and fauna.
Centrally lies the massif of Monte Perdido (3355 metres) which can be climbed as well.
Other summits are Tres Sorores, from where the valleys of Ordesa, Pineta, Añisclo and Escuaín come from. A sharply contrasting landscape: the extreme aridity of the high ground, where the rainwater and thaw filter through cracks and holes, contrasts with the green valleys covered in forests and meadows, where the water forms waterfalls and travels along canyons and ravines. Interesting and hard to climb is the Brecha de Rolando (1338 a 2804m), to arrive takes about 5 hours. In the park is als the starting point of the GR-11.
