Road 663 in Peru has a drop of 300 meters

Carretera 663 is one of the scariest roads in the world. Located near the Llata town, in Huanuco region of Peru, the road is only wide enough for one vehicle, and in many places bordered by a drop of 300 meters unprotected by guardrails. It’s one of the most hairpinned roads in the world.

Carretera 663

The road is 12.3km long. It’s gravel. Words can’t describe the road and pictures don’t do it justice. Carretera 663 follows the Marañon river. The road is in dreadful condition and requires strong nerves to negotiate it. The most challenging part of the road is along the Quebrada de Anlay - Desfiladero del Surria, a narrow gorge over the river. The road is bordered by a drop of 300 meters unprotected by guardrails, especially after an unlit tunnel. Any barriers along the edge afford little more than token protection; large stretches should be taken at a snail's pace and a lookout kept for vehicles coming from the opposite direction. The road includes more than 20 hairpin turns.
