Los Caracoles: The Most Beautiful and Challenging Road in Chile

Nestled in the heart of the Andes Mountains and close to the Argentine border, Los Caracoles—also known as “The Snail Road”—is a famed section of International Route 60 (Ruta 60). This winding road connects the Chilean city of Los Andes to the Libertadores border crossing, leading to Mendoza, Argentina. Known for its breathtaking scenery and treacherous switchbacks, Los Caracoles has earned its place as one of the toughest roads in the world.

Chileans have aptly named the road “Los Caracoles” (the snails) due to its 29 sharp hairpin turns that spiral like a snail’s shell, creating a road that challenges even the most experienced drivers. Rising from an altitude of 800 meters to a staggering 3,200 meters above sea level, this portion of Route 60 offers some of the most spectacular and nerve-wracking driving experiences in South America.

A Mythical Border Crossing

Among the more than 40 border crossings between Chile and Argentina, Los Caracoles remains the most mythical and impressive. The road winds through the Andes Cordillera, showcasing majestic landscapes and snow-capped peaks. On this route, travelers pass near Aconcagua, the highest peak in South America, towering at 6,959 meters.

The road is particularly challenging on the Chilean side, where the incline is steep, and the sharp, narrow turns make it one of the most difficult roads in the world to navigate. In contrast, the Argentine side offers a gentler slope, providing some relief to those who have successfully navigated the perilous Chilean ascent.

Winter’s Perils

Winter transforms Los Caracoles into an even more dangerous adventure. Snow and ice blanket the road, making the ascent and descent treacherous. The Cristo Redentor Tunnel, which connects Chile and Argentina at an altitude of more than 3,200 meters, often closes during winter due to snowfalls and rockslides. The tunnel itself stretches 3,080 meters, with 1,564 meters on the Chilean side and 1,516 meters on the Argentine side, and was inaugurated in 1980. However, winter conditions frequently force its closure, adding to the road’s infamy.

An Unforgettable Adventure

For travelers seeking adrenaline and unforgettable scenery, Los Caracoles is the ultimate road trip. Whether you’re behind the wheel of a 4×4 or riding a motorcycle, this stretch of road offers stunning views of the Andes and a slalom of dizzying curves. Each turn is both a test of skill and a reward of breathtaking natural beauty.

Los Caracoles is more than just a road; it’s a legendary experience, promising both danger and wonder, adventure and unforgettable memories. For those who brave its steep slopes and sharp bends, it offers a journey through some of the most beautiful landscapes in Chile and Argentina.
