Bolivia is a place of extremes. You have the blinding white of the salt flats and then you have the suffocating, vertical green of the Amazon basin. Somewhere in between sits a stretch of dirt and rock that basically defined "danger" for an entire generation of travelers. For years, the North Yungas Road earned its title as the world’s most dangerous road through a staggering body count. We aren't talking about a few fender benders here; we are talking about an estimated 200 to 300 people dying every single year on a path that barely stretches 40 miles.
It's a cliffside nightmare.
Honestly, calling it a "road" feels like a generous interpretation of the word. It is more of a ledge carved into the side of the Cordillera Oriental mountain range. On one side, you have solid rock. On the other? A sheer 2,000-foot drop with no guardrails. None. If you slip, you don’t just crash; you disappear into the canopy of the jungle below.
What actually makes it the world's most dangerous road?
Geography is the main culprit, but physics is the executioner. Most roads around the world follow some semblance of logic, but the North Yungas Road—often called El Camino de la Muerte (Death Road)—defies it. It connects La Paz, the highest administrative capital in the world, to the town of Coroico in the Yungas region. You start at nearly 15,000 feet in the freezing Altiplano and drop down to about 4,000 feet. That's a massive elevation change over a very short distance.
The moisture is constant. Clouds drift across the path, reducing visibility to almost zero in seconds. Because it’s a transition zone between the mountains and the rainforest, it rains. A lot. This turns the dirt surface into a literal slip-and-slide of mud and loose shale.
There's a weird local rule here that you won't find anywhere else in Bolivia. Drivers are required to drive on the left side of the road. Why? Because the driver’s seat is on the left, and by hugging the outer edge, the driver can see exactly where their wheels are in relation to the abyss. Imagine steering a heavy bus full of people while looking down at a 600-meter drop just inches from your tire. It’s a psychological gauntlet that many didn't survive.
The 1983 tragedy and the turning point
A lot of people think the "Death Road" label is just marketing for mountain biking tours. It isn't. The history is written in blood and mangled metal. The darkest day in the history of the world’s most dangerous road happened in July 1983. A crowded bus was navigating one of the tightest bends when it veered off the edge.
One hundred people died.

In a single moment, a whole community was devastated. That specific accident remains the worst traffic disaster in Bolivia's history. It’s the reason you see so many small stone crosses and makeshift altars lining the route today. Each one marks a spot where a truck, a car, or a bike went over. It’s a cemetery that happens to be a transit route.
The biking boom and the new era of risk
Something strange happened in 2006. The Bolivian government finally finished a new, modern bypass. This new route has two lanes, actual pavement, and—praise be—guardrails. It took the heavy traffic, the buses, and the produce trucks away from the old North Yungas Road.
You’d think the death toll would drop to zero, right? Not exactly.
Instead of closing the road, it became a playground for adrenaline junkies. Every morning in La Paz, vans load up with mountain bikes and tourists from every corner of the globe. They want to ride the world’s most dangerous road. It’s become a bucket-list item, a badge of honor for backpackers.
But here’s the reality check: it’s still incredibly dangerous. At least 18 cyclists have died on the route since the biking tours became popular. The danger has shifted from "falling off a bus" to "overestimating your skill on a mountain bike while traveling at 30 miles per hour on wet gravel." Gravity doesn't care if you're on two wheels or six.
The common mistakes tourists make
- Braking too hard: The surface is loose. If you slam your front brake because you’re scared, you’re going over the handlebars.
- Looking at the view: It sounds stupid, but the scenery is so beautiful it’s distracting. One second of looking at a waterfall instead of the path is all it takes.
- The "Invincibility" Complex: Many riders assume that because they paid for a tour, they are safe. The guides are great, but they can't stop you from making a bad turn.
- Gear failure: Using cheap tours with old bikes is a recipe for disaster. If your brakes fail on a 15% downhill grade, you are in serious trouble.
Is it actually the "most dangerous" anymore?
This is where things get nuanced. If we are looking at raw numbers, some roads in India or the Sichuan-Tibet Highway in China might have higher total fatalities simply due to the sheer volume of people using them. However, when you look at the "danger per mile" or the "margin for error," the North Yungas Road is still a top contender.
The Guoliang Tunnel in China is terrifying because it’s carved through a mountain, but it’s generally stable. The James Dalton Highway in Alaska is isolated and frozen, but it’s wide. The North Yungas Road is unique because it combines extreme heights, narrow passages (sometimes only 10 feet wide), and horrific weather conditions. It is a perfect storm of environmental hazards.

Local experts like those at Gravity Bolivia, who pioneered the bike tours, emphasize that the road hasn't changed; only the users have. The rock is still crumbly. The waterfalls still pour onto the road surface. The fog still rolls in without warning.
What you need to know before going
If you're actually planning to visit, don't just wing it. This isn't a Disney ride. You are entering a high-altitude, high-risk environment where emergency services are hours away.
First off, check the season. Going during the rainy season (December to March) is basically asking for trouble. The mud is thick, and the landslides are frequent. It’s not uncommon for sections of the road to just... disappear.
Secondly, choose your operator based on their mechanics, not their price. There are plenty of "budget" tours in La Paz that will take you down for $40. Don't do it. You want hydraulic disc brakes that have been serviced that morning. You want a helmet that isn't cracked. This is the one time in your life where being a "cheap traveler" could literally kill you.
Essential Gear Check
- Full-face helmet: Some tours only give you standard bike helmets. A full-face one saves your jaw if you slide.
- Layers: It's freezing at the top (La Cumbre) and tropical at the bottom.
- Insurance: Make sure your travel insurance specifically covers "high-risk activities" or "mountain biking." Many standard policies have a fine-print exclusion for the North Yungas Road.
The cultural impact of the road
For the people of Coroico and the surrounding valleys, the road was a lifeline, not a tourist attraction. Before 2006, if you wanted to get your citrus crops or coca leaves to the market in La Paz, you risked your life. Every single trip was a gamble.
There is a deep sense of spirituality attached to the route. You’ll see drivers tossing coca leaves out the window or pouring a bit of beer on the ground before a journey. This is an offering to Pachamama (Mother Earth) for safe passage. To the locals, the world’s most dangerous road isn't a thrill; it's a testament to the harshness of Andean life.
The transition to a tourist-centric economy has changed the vibe. Now, instead of trucks carrying fruit, you see support vans carrying GoPro batteries and spare inner tubes. It has brought money into the region, but it has also turned a site of many tragedies into a bit of a spectacle. It’s worth remembering the history of the families who lost loved ones here while you're taking your "I survived" selfie at the bottom.

Actionable steps for the safe traveler
If you are determined to see the North Yungas Road, do it the right way.
Start by acclimating in La Paz. Don't try to ride the road the day you fly in. The starting point is at 4,700 meters (over 15,000 feet). If you have altitude sickness, your reaction time will be sluggish. Give it three days.
Verify your tour company's safety record. Ask specifically when they last replaced their brake pads. A reputable company won't mind the question. Look for names like Gravity or Altitude—they have been doing this for decades and have the most robust safety protocols.
Stay focused. The most dangerous part isn't actually the narrowest ledge; it's the flatter sections where people get overconfident and pick up too much speed. Keep your eyes on the track.
Respect the environment. The Yungas is a fragile ecosystem. Don't leave trash, stay on the designated path, and remember that even though the big trucks are gone, a few local cars still use the road. They always have the right of way.
The North Yungas Road is a haunting, beautiful, and terrifying piece of infrastructure. It serves as a reminder that despite all our technology, nature still holds the upper hand in the high Andes. Whether you view it as a death trap or a marvel of engineering, it remains a place that demands absolute respect. If you give it that respect, you'll come away with the story of a lifetime. If you don't, the crosses on the hillside serve as a somber warning of what happens next.
