The town of CASMA, 170km north of Barranca, marks the mouth of the well-irrigated Sechin River Valley. Surrounded by corn and cotton fields, this small settlement is peculiar in that most of its buildings are just one storey high and all are modern. Formerly the port for the Callejón de Huaylas, the town was razed by the 1970 earthquake, whose epicentre was just offshore. There’s not a lot of interest here and little reason to break your journey, other than to try the local speciality of duck ceviche (flakes of duck meat soaked deliciously in lime and orange juice) or to explore the nearby ruins, such as the temple complex of Sechin, the ancient fort of Chanquillo and the Pañamarca pyramid, 20km north.
