Huacachina is a village built around a small oasis and surrounded by sand dunes in southwestern Peru. It is about five kilometers from the city of Ica in the Ica District of Ica Province.

To compensate for the loss, and preserve the oasis as a destination for tourists, local business groups began pumping water into the lake in 2015.
