Huascarán National Park (PNH) has been recognized as Biosphere Reserve by UNESCO in1977, and declared a World Heritage Site in 1985. It contains wealth of flora and fauna preserved in their natural ecosystems, and snowy and exquisite landscapes. The most representative flora is Puya Raimondi. It belongs to the family of bromeliaceae species, which can grow up to 12 meters tall and is a native plant of Peru. PNH has registered 131 species of birds, and unique mammals such as the ornaments Tremarctos "Oso de Anteojos”, the Puma, the Andean cat, and others. Since the mid-nineteenth century, there has been an interest to investigating the natural and cultural wealth of this privileged land. One of the first researchers in the area was Antonio Raymondi, the famous Italian scientist. Later, German, Austrian and American scientists have investigated several areas in the Cordillera Blanca.  There is widespread interest to study the Huascaran National Park, because of its unique biodiversity.

The Park's greatest wealth is the snow-capped mountain ranges, which has 57 peaks over 5700 meters; its highest peak is Huascaran located at 6768m (22,206 feet), and others like the snowy peaks Alpamayo, Chacraraju, and many others are recognized worldwide for their beauty and splendor, making this region of mountains an international attraction.

At south of the Cordillera Blanca, outside the limits of HNP, we find Cordillera Huayhuaysh which contains the great Yerupajá (6634m), the second highest mountain in Peru. This wonder of the Peruvian Andes is the second highest mountain range in the tropical zone in the world, after the Cordillera Blanca. It has 6 peaks of over 6000 m.a.s.l. and 15 others above 5400m.
