比利牛斯山脉在任何季节都很引人注目，但在夏季温暖持续到秋季的年份尤其美丽，自最早的文明在那里扎根以来，比利牛斯半岛一直是伊比利亚半岛和欧洲其他地区之间的天然边界。位于山脉中心的Ordesa y Monte Perdido国家公园创建于1918年，并于1982年扩建。如今，它已成为联合国教科文组织的世界遗产。

该公园拥有陡峭的悬崖和深邃、翠绿的山谷，是摄影师的梦想，拥有由比利牛斯山脉剧烈的海拔变化形成的卓越地质地貌和多样生态。该地区是几个只能在这里找到的物种的家园，包括比利牛斯羚羊和比利牛斯山羚羊，或水鼹鼠。这种被认为是该地区最稀有和最重要的哺乳动物，布卡多山羊或比利牛斯山羊，尽管进行了保护工作，但于2000年1月灭绝。

Rio Arazas in Ordesa and Monte Perdido National Park, Pyrenees, Spain

Striking in any season, but particularly beautiful in years when the warmth of summer stretches into fall, the Pyrenees have served as a natural border between the Iberian Peninsula and the rest of Europe since the earliest civilizations took root there. Located in the center of the range, the Ordesa y Monte Perdido National Park was created in 1918 and expanded in 1982. Today it is a UNESCO World Heritage Site.

Boasting sheer cliffs and deep, verdant valleys, the park is a photographer's dream, with a landscape marked by remarkable geological landforms and diverse ecologies shaped by the drastic elevation changes of the Pyrenees. The region is home to several species that can only be found here, including the Pyrenean chamois and the Pyrenean desman, or water mole. The mammal considered the most rare and important in the region, the bucardo or Pyrenean ibex, went extinct in January 2000 despite preservation efforts.
