In the heart of the Cordillera Blanca, in the Ancash region, the Huascarán National Park will celebrate its 50th anniversary in 2025. Created in 1975 and listed as a UNESCO World Heritage Site ten years later, this Peruvian natural sanctuary is one of the most impressive mountain ecosystems in Latin America. With its vertiginous peaks, turquoise lakes, iconic wildlife and traditional villages, the park is much more than a trekking destination: it is a living model of conservation, ecological resilience and harmonious coexistence between humans and nature.
Huascarán National Park: spectacular geography at the service of biodiversity
Located at an altitude of over 6,000 metres, Huascarán National Park is home to the highest part of the tropical Andes. It covers 340,000 hectares and includes around 30 peaks rising to over 6,000 metres, including the famous Nevado Huascarán, Peru’s highest peak at 6,768 metres.
But what makes this site truly exceptional are its contrasts: more than 600 glaciers, around 300 glacial lakes in unreal colours, narrow valleys carved out by time, and vertiginous canyons. These varied landscapes are home to extraordinary biodiversity, with many endangered species such as the Andean condor, the spectacled bear, the puma and the vicuña.
Among the botanical treasures, the Puya raimondii deserves a special mention. This giant plant, endemic to the high cordillera, can reach up to 12 metres in height and lives for over a century before flowering just once. It embodies the uniqueness and resilience of life in the Andes.
A paradise for trekking and mountaineering
The reputation of Huascarán National Park among hikers and mountaineers from around the world is well established. It is one of the top trekking destinations in South America, with something for everyone, from contemplative walkers to seasoned mountaineers.
The Santa Cruz trek, in particular, is considered one of the most beautiful circuits on the continent. Over four to five days of walking, it crosses majestic glacial valleys, passes over passes at over 4,700 metres and offers unforgettable views of Andean giants such as Alpamayo and Taulliraju.
Another must-see is Laguna 69, accessible in a day’s walk from the Llanganuco Valley. Perched at over 4,600 metres, this intense blue lagoon is one of the most photographed sites in the park, symbolising the fragile beauty of the high-altitude landscapes.
For the more experienced, climbing Nevado Huascarán is a major technical challenge. Although relatively accessible in terms of pure technical difficulty, it requires excellent physical condition, careful acclimatisation and great caution in the face of the risks associated with altitude and crevasses.
An exemplary approach to responsible tourism
Since its creation, Huascarán National Park has established itself as a model of sustainable management in high mountains. Long before the concept of ecotourism became a global trend, the Peruvian authorities put in place innovative strategies to combine environmental preservation with the development of local communities.
The economic benefits of tourism directly benefit the inhabitants of the surrounding villages, particularly through the training of local guides, the promotion of Andean crafts and the enhancement of traditional agricultural practices. This virtuous circle enables hundreds of Quechua families to live with dignity while actively participating in the protection of their territory.
This inclusive approach also helps to enhance the authenticity of the tourist experience. Visitors are not just spectators of a spectacular setting: they become actors in a respectful form of tourism, immersed in a living and welcoming culture.
Climate issues and contemporary challenges
Although Huascarán National Park remains a haven of unspoilt nature today, it is not immune to global threats. Climate change is hitting the tropical Andes hard, with accelerated glacier melt. Over the past 30 years, the Cordillera Blanca has lost nearly 30% of its glacier area, compromising the hydrological stability of the entire region.
The Pastoruri Glacier, long an icon for visitors, is now classified as ‘extinct’. It is the focus of an environmental education programme called ‘Ruta del Cambio Climático’ to raise awareness among tourists about the climate emergency.
Other threats to the park include mining pressure on the periphery, water use conflicts, agricultural expansion and poorly regulated tourist influx in certain areas. Faced with these challenges, the Peruvian authorities, with the support of UNESCO and local NGOs, are stepping up monitoring, education and long-term planning.
On the occasion of its 50th anniversary, Huascarán National Park has reaffirmed its ambition for the coming decades: to become a laboratory for innovation in sustainable tropical mountain management, a research hub for climate scientists, and a flagship destination for ethical tourism in Latin America.
Easily accessible from Lima (one-hour flight to Huaraz), it is now an essential stop on any itinerary in Peru. Whether you come for a legendary trek, an alpine climb, or simply to reconnect with nature and Andean cultures, Huascarán promises an unforgettable experience.
