Zona reservada Lomas de Ancón, Protected natural area in Lima Department, Peru.

Lomas de Ancón is a protected reserve that spans three provinces and combines desert landscapes with coastal hills covered by seasonal vegetation. The terrain changes dramatically across different seasons due to shifts in weather patterns and moisture availability.

Lomas de Ancón was declared a reserved zone on 6 October 2010 by Ministerial Resolution No. 189-2010-MINAM. The reserve covers 10,962.14 hectares across the provinces of Huaral, Lima and Canta in the Lima department, protecting the desert and lomas ecosystems and their biological diversity.

The reserve lies across the provinces of Huaral, Lima and Canta, so its lomas are shared ground for several districts rather than one community. Its name comes from the nearby town of Ancón, on the coast north of Lima, and from the lomas, the fog-fed hillsides that green over in winter. The area was declared a reserved zone by Ministerial Resolution No. 189-2010-MINAM.

The reserve covers 10,962.14 hectares across the provinces of Huaral, Lima and Canta, so access points differ by sector; the Panamericana Norte passes near Ancón. Coastal fog feeds the lomas in winter, and the ground is loose desert soil, so wear sturdy footwear and carry water.
