The Jequetepeque Valley stretches east from the Pacific coast at Pacasmayo, following the river inland through rice paddies, sugar cane, and eventually the foothills of the Andes. The valley was one of the most densely populated stretches of pre-Columbian coastal Peru — a highly productive agricultural zone that supported successive cultures from the Formative period through the Moche, Lambayeque (Sican), and Chimú. Archaeological sites dot the valley floor; many are unexcavated and virtually unknown to visitors, their adobe walls eroding quietly back into the desert.
The drive up the valley on the road to Cajamarca passes through a landscape that has been continuously farmed for three thousand years. Near the mouth of the valley, the site of Cerro de Dos Cabezas preserves an unexcavated Moche ceremonial mound whose twin-peaked profile gives it its name. The communities along the valley floor still grow rice and sugar using traditional irrigation channels that trace their origins to pre-Inca engineering.
The Gallito Ciego dam, built in the 1980s, impounds the upper valley about an hour east of Pacasmayo. The reservoir it created — a vivid blue sheet of water set against brown hills — is popular with locals for fishing and weekend boating, and marks the point where the agricultural coastal plain gives way to the drier Andean foothills. The drive itself is best done at dawn when the fields are being worked and the morning light picks out the geometry of irrigation channels against the flat valley floor.
From Pacasmayo the valley makes a comfortable half-day excursion by taxi or hired car. There is no organised tourist infrastructure along the route — which is part of the appeal. You will share the road with sugar-cane trucks, motorised rickshaws, and the occasional herd of goats, and the roadside villages have simple restaurants serving fresh river fish.
