Not your average suburban sighting, Huaca del Dragón—also known as Huaca Arco Iris—is among the best-preserved Chimu ruins, and it’s just five kilometers (three miles) outside of central Trujillo. A thick wall encloses the 12th-century site, where you’ll come across a temple with a repeating rainbow motif—as well as bins that were discovered to contain infants’ bones. You’ll also find a museum on the premises.
