Huacachina is a natural oasis 5km from the city of Ica in the coastal desert of southern Peru — a genuine lagoon of groundwater surrounded by sand dunes that reach 100 metres in height. It is one of the only natural oases in the Americas and the only significant one on the South American continent. The lagoon (roughly 400m × 100m) is fed by underground aquifer water rising through the desert floor; it exists because the water table in the Ica valley is high enough at this point to reach the surface between the dunes. The dunes surrounding it belong to the coastal extension of the Atacama Desert that runs along this stretch of the Pacific coast. Approximately 300 people live permanently in the cluster of guesthouses and restaurants immediately around the lagoon. The dunes are the tallest in South America accessible for sandboarding and dune buggy, and the combination of the oasis landscape with the dune activity has made it one of the most-photographed travel images in South America — the single image of a palm tree by a lagoon surrounded by 100-metre dunes that appears on every Peru travel magazine cover.
Crowd: moderate · Noise: moderate · Best time: Late afternoon — the sunset dune buggy tour is the signature experience. Tours depart around 3:30–4pm and time the final dune summit for the sunset over the desert. Morning tours (8–9am) offer cooler temperatures and better light for photography but the afternoon sunset tour is the iconic product.

The Huacachina lagoon exists because of an anomaly in the Ica valley's hydrogeology. The Ica River, coming down from the Andes, has historically recharged an underground aquifer beneath the desert floor. At the Huacachina point, the water table is close enough to the surface that it breaks through between the dune crests to form the lagoon. The same aquifer feeds the pisco grape vineyards that surround the Ica valley — the vines are irrigated by groundwater from the same underground system. Since the mid-20th century, industrial agricultural expansion in the Ica valley (particularly asparagus and grape cultivation for export) has drawn down the aquifer significantly, and the Huacachina lagoon level has dropped measurably. Ica city now pumps water into the lagoon to maintain its level — it is still a natural water body but it is partly maintained. The dunes surrounding it are unaffected by the water table; they are a geological feature of the coastal Atacama that pre-dates the oasis and will outlast it.
