Serpentín Pasamayo is a very dangerous coastal road located in the Lima Province of Peru. The road has no safety fences. One mishap and you plunge off the cliff and into the sea.
The road, part of the Carretera Nacional 001B, is asphalted. It’s 22.6 km long and links Chacra and Santa Rosa. The road is intended for heavy vehicles. Extremely dangerous with fog, between April and December. The road was bypassed by a new road called Ruta nacional PE-1. But the heavy traffic is still using this road.
High level of road fatalities along the road (more than 150 in the last 30 years). 48 people were killed 3rd January 2017 when a bus went over a cliff. Especially treacherous at nights, with low visibility and high humidity. The road is bordered by a drop of hundreds of meters (many hundreds of feet) unprotected by guardrails. Asphalt is very slippery at nights and during rains. It follows 52 never ending turns. The road was originally designed as a railroad (in 1870’s). The current road was built in 1940. Extreme drop offs (more than 100 meters). Stay away if you're scared of heights. It is recommended that beginner riders avoid this road.
