Chan Chan functioned as the largest pre-Columbian city in America from 850 AD until its fall to the Incan Empire in 1470 AD. It encompasses over 20 square kilometers but the average traveler will only visit the city center (6 square km).
Chan Chan is just 5km outside of Trujillo and can easily be reached by taxi or colectivo. If you choose the colectivo, look for one headed to “Huanchaco” and tell the driver to let you off at “Cruce de Chan Chan”. This will be a stop on the main road. Once you get out, you’ll see a long dirt road. Follow the dirt road for a few hundred meters and you’ll see the entrance to the ruins and a small parking lot on your left. The admission fee is 11 soles.
The ideal time for photos would be either when the site opens at 9:30am or later in the day, just before it closes, at 4:30pm. This will allow you to avoid the harsh shadows created by the mid-day sun.
