Regional Conservation Area of Huacachina lagoon, Regional conservation area in Ica Province, Peru

The Regional Conservation Area of Huacachina lagoon covers 2,458.25 hectares of the Ica desert, about 3 km southwest of the city of Ica. Its roughly rectangular area measures 6.5 km north to south and 4.6 km east to west, with the Huacachina oasis at its northeastern corner. The reserve takes in the lagoon surface and its western shore, crossed by a sand ridge rising to 660 m.

The lagoon became popular in the early 1900s when visitors arrived seeking its reported healing properties. This growing interest led to the area's development and eventually its protection as a conservation zone.

The reserve's name comes from the Huacachina oasis at its northeastern corner, a lagoon the regional government of Ica is charged with managing for biological, cultural and landscape diversity. The 2014 decree that created the area also set sustainable use of its natural resources as a goal, so the dunes and water are worked as well as protected.

The reserve lies about 3 km southwest of the city of Ica and covers roughly 6.5 km north to south and 4.6 km east to west, with the Huacachina oasis at its northeastern corner. The lagoon and its western shore fall inside the boundary, so the dunes west of the water are the protected ground. Access is from Ica by road.

The reserve covers 2,458.25 hectares, an almost rectangular block about 6.5 km north to south and 4.6 km east to west, with the Huacachina oasis at its northeastern corner. A ridge rising to 660 m runs north to south through the dunes. The lagoon and its western shore lie inside the boundary.
