The park's defining feature is the cardón—a massive columnar cactus that dominates the skeletal landscape alongside spiny shrubs, xerophytic scrub, and drought-resistant small trees adapted to intense solar radiation and minimal rainfall. This is terrain of dramatic contrasts: rocky bajadas give way to canyon systems carved through stratified mountains, their pale stone faces catching the low-angle light in hues of rust, cream, and deep purple. The elevation gradient from around 1,600 to over 3,200 metres creates distinct ecological zones, each harbouring specialist wildlife. Birds of prey hunt the thermals above the ridges, while ground-dwelling birds and small mammals shelter among the cardón forest and rocky outcrops. Nocturnal predators and burrowing vertebrates emerge as temperatures drop, their presence revealed by tracks in the fine desert dust and the occasional sighting along quieter trails.
