Huascarán National Park, Protected area in Ancash Region, Peru

Huascarán National Park is a protected area in Ancash Region, Peru, covering 340,000 hectares along the Cordillera Blanca and enclosing the country's tallest summit at 6,768 meters (22,205 feet). The landscape includes turquoise lakes, deep valleys, and retreating glaciers framed by sheer rock walls and grass-covered plateaus.

Senator Augusto Guzmán Robles brought the first proposal to protect this mountain region to Congress in 1960, but it took until 1975 for the area to be officially declared a national park. UNESCO later granted it World Heritage status, recognizing its role in safeguarding Andean ecosystems.

The name derives from the Quechua word waska, meaning 'rope' or 'cord', referring to the two linked summits of the Huascarán massif; it was recorded as 'Huascan' on Antonio Raimondi's 1850 map and became 'Huascarán' in the 20th century. Communities inside the park still raise livestock on the puna, a practice park authorities regulate.

Mountaineering and trekking require a permit and a certified mountain guide, as many routes cross remote terrain and climb to altitudes that demand acclimatization to altitude sickness. The dry season from May to September offers more stable weather, while the rainy season can make trails slippery and rivers impassable.

The rare Puya raimondii, the world's largest bromeliad, grows here above 4,000 meters (13,123 feet) and flowers only after decades before dying. In remote zones, the endangered Andean mountain cat lives, a shy animal that travelers rarely see.
