How dangerous is the drive from Barba Blanca to Autisha?

Okay, thrill-seekers, listen up! If you're in the Huarochirí Province of Peru's Lima Region and fancy a drive that'll make your palms sweat, the LM-116 (Barba Blanca to Autisha) is calling your name.

This isn't your average Sunday cruise. We're talking about a 20km stretch carved right into the side of the Santa Eulalia River canyon, hugging vertical limestone walls. The road surface? Think gravel and packed earth, often so narrow that passing another vehicle becomes a delicate dance of reversing on ledges with a sheer drop of hundreds of meters on one side! Oh, and did I mention there are no guardrails?

The views are insane, but the danger is real. This road climbs from near the Autisha Bridge (around 2,100m) and the drop-offs are truly dizzying. Vertigo sufferers, consider yourselves warned! Beyond the heights, you'll have to watch out for rockfalls that regularly block the path. The curves are blind, so honk your horn before every turn to avoid a head-on collision. It's a serious workout for your vehicle too, putting a strain on your brakes and cooling system.

A high-clearance 4x4 is essential for this adventure. While locals use the road, it's definitely not for the faint of heart. Focus is key here - one mistake could be fatal.

The best time to tackle this beast is during the dry season (May to September). Avoid the Andean winter when the gravel turns into a slippery mud bath and landslides become a major threat. Despite the risks, the LM-116 offers access to some incredible, untouched canyon scenery. Make sure your tires are in top condition, buckle up tight, and get ready for the ultimate cliff-hanging experience!
