If there's one must-see archaeological site in the region, this is it. The Temples of the Sun and the Moon, attributed to the Moche period, are more than 700 years older than Chan Chan, yet parts of the complex are remarkably well preserved. Located on the south bank of the Río Moche, the main attraction here is the Huaca de la Luna with its phenomenal multicolored friezes. The entrance price includes an English-speaking guide; individual travelers need to wait for a group to fill. The larger Huaca del Sol is closed to visitors.
