The range is rich in Andean wildlife which is only rarely seen elsewhere. The park is home to several thousand alpacas, llamas and vicuñas, and also to Bolivia’s densest condor population. Pumas and spectacled bears still roam the most isolated regions. Glaciers adorn the mountain tops and the many lakes support a variety of aquatic birds. In the drier valleys you’ll find cacti and humming-birds whilst in the more humid valleys you can see queñua trees, native to the region.
