Oasis de Huacachina
Start at the water. The Oasis de Huacachina is a small natural desert lake with a village built around it, home to around 100 permanent residents and a great many more visitors each year. People call it the "oasis of America", and in 1991 Peru put it on the back of the 50 nuevo sol note. The promenade around the lagoon is open at any hour and costs nothing, so take your time here: this is the free part of the day.
The name comes from Quechua: wakachina means "guard" or "conceal", possibly short for wakachina qucha, the "hidden lagoon". The legend fits. A beautiful native princess undressed to bathe, saw in her mirror a hunter approaching from behind and fled; the mirror she left behind became the lake. In another version the pool she was bathing in stayed behind as the lagoon, and the folds of her mantle, streaming out as she ran, became the dunes around it. Some say she never left and still lives in the water as a mermaid.
Watch what people do at the edge. Local tradition holds that the water and mud heal, and locals and visitors alike bathe here or cover themselves in mud against arthritis, rheumatism, asthma and bronchitis. Huacachina began as a resort for families from nearby Ica and is still geared to them, even as more and more travellers arrive for the sandboarding.
The lagoon is more fragile than it looks. It was fed by natural seepage from underground aquifers until increased well drilling in the early 2000s began to threaten that supply. Since 2015 local business groups have pumped water into the lake to keep the oasis alive for visitors. In 2016 it was announced that Marino Morikawa, the Peruvian scientist whose nanobubble system cleaned lake El Cascajo, would lead a restoration project; by 2020 nothing more had been heard of it.
From the promenade, the first leg is long: 5110 m, about 71 minutes on foot to the checkpoint of the conservation area. Let the GPS route lead the way.
