It's the biggest archaeological representation of a human in the world – a gargantuan 86m high – and yet little is really known about the 'Giant of the Atacama.' Reclining on the isolated west slope of Cerro Unita 14km east of Huara, the geoglyph is thought to represent a powerful shaman. Experts estimate that the giant dates from around AD 900. Don't climb the slope, as it damages the site.
The Huara–Colchane road, the main Iquique–Bolivia route, is paved; only the very short stretch (about 1km) from the paved road to the hill itself crosses unpaved desert. The isolated site is 80km from Iquique; the best way to visit is to rent a car or taxi, or take a tour.
