Stay away if you're scared of heights due the severe drops off (some of them higher than 600m). A 4WD vehicle and an experienced driver are recommended.

The road is pretty steep. Starting from the Tablachaca river on the Ancash 100 road (at an elevation of 1.403m above the sea level), the road is 23.8km long. Over this distance, the elevation gain is 1.492 meters. The average percentage is 6.26% but the maximum slope is 10.2 %. This road tests the skill, and courage, of any driver.

One mistake and it's a free fall to your death.
