This post is part 4 of 8 in the series Cordillera Blanca Travel Guide

Most of the drives that we include in our Epic Drives series of posts are long, remote, and arduous. But what the drive through Cañon del Pato in Peru lacks in length and difficulty it makes up for in sheer geographical wackiness as two major mountain ranges practically touch in this scenic canyon. Don’t miss our dramatic dashcam video.

Welcome to Cañon del Pato in Peru

A stretch of road through Cañon del Pato (which may also be spelled Canon del Pato, Pato Canon, Canyon del Pato, or Pato Canyon) connects the town of Caraz to the town of Huallanco where there’s an important hydroelectric plant.

The word pato means duck in Spanish, but this road is not named after tasty waterfowl–turns out, Huallanco used to be called Patos.

Some people morbidly refer to this area as the Valley of the Dead Nuns because a vehicle full of nuns went over the edge of this road which is narrow and has many sheer drop-offs (though there are some guard rails in place now).

And did we mention the tunnels?

During sections of this drive it felt like we were constantly exiting or entering a tunnel.

The route through Cañon del Pato travels through an area where the Cordillera Blanca and the Cordillera Negra mountain ranges get within 20 feet (6 meters) of each other. This wicked-close geography meant that engineers had to hand carve 35 tunnels through sheer rock to allow traffic to pass from the eastern side of the Cordillera Negra to the western side of the Cordillera Negra.

You can see three separate tunnels in this short stretch of road through Cañon del Pato.

It all makes the famous Going to the Sun road in Glacier National Park in the US state of Montana look like child’s play. Not surprisingly, the tunnels and the paved (but potholed) road seemed to be in a perpetual state of maintenance and we passed a lot of road workers who shouted hello to us as we drove by.

One more tunnel…

Driving through Cañon del Pato

Shortly out of the town of Caraz the canyon narrows and drops fast as the road descends from 7,402 feet (2,256 meters) in Caraz to 1,400 feet (426 meters) in the town of Huallanca.

35 tunnels canon del pato

Tunnels, tight canyon walls, and rushing water were mainstays of this drive.

There are lots of waterfalls along the way including one predictably called Bridal Veil. There are also a bunch of manmade waterfalls that divert even more water to the hydroelectric plant in Huallanca.

Classic, curvy Cañon del Pato.

With 35 tunnels in a one-way length of just under 8 miles (12 km), that’s about four tunnels for each mile. Sometimes we were no sooner out of one tunnel than we were entering the next one.

And, yes, we honked our horn a lot inside the tunnels, though no other drivers seemed to be doing that…Some of the tunnels are just rough rock inside and other tunnels have been nicely finished.

Karen walking along a short trail to see the spot where two mountain ranges practically touch in Peru’s Cañon del Pato.

Inside tunnel 11, for example, there is a nice little siding you can park in before walking along a 650 foot (200 meter) trail to see the tightest point in this rugged and steep canyon as the Cordillera Blanca and Cordillera Negra mountain ranges come within 20 feet (6 meters) of each other.

meeting of the cordileras

Don’t miss the very short walk to the union de las cordilleras (meeting of the mountain ranges) where the Cordillera Negra and the Cordillera Blanca are just 20 feet (6 meters) apart.

This point is called union de las cordilleras, or meeting of the mountain ranges and the trail that gets you to the viewpoint outside tunnel 11 is narrow in places with steep drop-offs. Use the safety ropes they’ve installed along the way.

One of the water diversion tunnels that bring water to the hydroelectric plant in the town of Huallanco.

After admiring the hydroelectric plant down in steamy, low-altitude Huallanco (there’s really not much else to see there), we turned around and drove the road back up to Caraz.
