Located in the department of Ancash, the Rio Santa drains the majestic peaks of Peru’s ominous Cordillera Blanca. It runs in a Northerly course for most of its journey before turning west towards the ocean. It is best to run the river in the heart of the rainy season from December to March when several thousand CFS is pumping through the river corridor. The runs dries up and is pretty bony from June through November.
There are multiple sections of the river one may chose to run depending on time and ability. The fact that a paved road follows the majority of the river allows for easy access and unlimited bail out opportunities. In the Canyon Del Pato 100 km below Huaraz the water is taken out of the river for a hydroelectric project. This 10 km dewatered stretch is a mandatory portage.
The town of Huraz lies at 3000 meters. From this point one can put on at just about any point along the river’s descent to the Pacific Ocean. A description of the length and gradient (highlighted in green) of each section follows:
