Fodor's Expert Review Pañamarca
Several ruins can be found near the town of Casma, but the heavily weathered Mochica city of Pañamarca is the one to see after Sechín (below). Located 10 km (6 miles) from the Pan-American Highway on the road leading to Nepeña, Pañamarca has some interesting murals. If they're not visible right away, ask a guard to show you, as they are often closed off. The site was later occupied by the Incas. A taxi will take you to the ruins for about S/20 an hour; negotiate the price before you leave.
