A high Andean zone comprised of the Cordillera Blanca (White Range), the highest range of tropical mountains in the world, with 27 peaks measuring over 6,000 metres above sea level. Due to its great variety of flora and fauna, the National Park was awarded World Heritage status by UNESCO in 1985.
At the foot of the mountains are areas with microclimates that support a variety of flora and fauna, such as the area at the foot of Huascarán Mountain (6,768 metres above sea level), very close to Llanganuco lagoon. A walk along the María Josefa path reveals a small forest, with palm trees, waterfalls and beautiful orchids, including the waqancu or Masdevalia amabilis, with its fuchsia and white flowers. Other varieties can also be seen, including the Altensteinia, Epidendrum and Stelis, among others.
