A small and unflustered Peruvian coastal town; there is little to do in Casma except watch the whirring of passing buses. The big draw here is the archaeological site of Sechín, about 5km away. Casma’s once-important colonial port (11km from town) was sacked by various pirates during the 17th century; the town today is merely a friendly blip on the historical radar.
From here, the Pan-American Hwy branches off for Huaraz via the Callán Pass (4225m). This route is tough on your backside but offers excellent panoramic views of the Cordillera Blanca. Most points of interest in town lie along the Pan-American Hwy, between the Plaza de Armas in the west and the petrol station in the east.
