Travel to Huaraz

There are several daily buses to and from Chimbote & Trujillo. Movil Tours & Transportes Linea are the best (US$14, 9 hours to Trujillo), followed by Chinchaysuyo & Comite 14, all of which only travel by night, & continue to Trujillo. All night buses travel on the tar sealed road from Huaraz to Pativilca (Caral is near there) to the Panamerican Highway, midway between Trujillo & Lima.

Transportes Linea [3], America Express & others run from Trujillo from 6AM or earlier to catch the 8-8.30AM bus of Turismo Huaraz & Yungay Express from Huaraz via Caraz & the spectacular Cañon del Pato. It's a rough 8 hour bus ride, the buses are basic for the unsealed road (Caraz to Chimbote) and may be overcrowded between Caraz & Huaraz. The views are stunning. Price is around US$7 (S/. 25). The schedule is seasonal and not operating as of Nov. 2012. Less spectacular route via Casma is running 4-5 times a day. If you have your own vehicle, obtain permission (& confirmation of entrance times if maintenance is in progress) from Proyecto Chavimochic in Trujillo Viru to leave the Panam (485 km north of Lima) via the well kept Brasileiros maintenance road alongside the canal to the north bank of the Santa River to Cañon del Pato. It is possible to cover Trujillo to Caraz in 5 hours (+ photo stops) on this straighter, smoother road. Almost 40 tunnels are large enough for all but the largest tourist buses.

There are also day buses between Huaraz & Chimbote via the Callan Pass, Pariacoto & Casma (for Sechin). Longer, rougher & not quite as visually stunning.
