The Cordillera Huayhuash is renowned for its peaks and abundant water features. Numerous glacial lakes, rivers, and streams dot the landscape, creating picturesque vistas and vital habitats for diverse flora and fauna. The turquoise waters of lakes such as Jahuacocha and Carhuacocha reflect the surrounding snowy peaks, adding to the region's beauty.

Biodiversity

Flora

The Cordillera Huayhuash is part of the Central Andean wet puna ecoregion, characterized by high-elevation grasslands and patches of forest. Since its designation as a Reserved Zone in 2002, the area has been protected from activities like mining, allowing its ecosystems to thrive. Research by Roberto Arevalo of The Mountain Institute has identified 272 plant species in the Cordillera Huayhuash. Among the notable flora are native tree species such as the Andean alder and members of the Polylepis genus, adapted to the high-altitude environment.

Fauna

The region's biodiversity includes 61 bird species, 14 mammals, two amphibians, and two fish species. Noteworthy wildlife includes the Andean mountain cat and taruca (a type of deer) and several bird species such as the giant cone bill, tit-like dacnis, torrent duck, Andean condor, peregrine falcon, and giant coot. Ten of the bird species identified are considered threatened, underscoring the importance of the area's conservation efforts.

Climate and Trekking

Climate

The climate in the Cordillera Huayhuash varies significantly with altitude but generally features a wet season from November to April and a dry season from May to October. During the dry season, clear skies and mild daytime temperatures make it the optimal time for trekking, while nights can be cold, particularly at higher elevations.
