If you stand at the edge of the North Yungas Road, about 56 kilometers northeast of La Paz, the first thing you notice isn't the view. It’s the silence. Then, the wind kicks up, and you realize the ground beneath your boots is basically loose shale and prayer. Most people know it as la carrera de la muerte—the Death Road. It’s a narrow ribbon of dirt that clings to the side of the Cordillera Oriental mountain range like a scar.
For decades, this wasn't a tourist attraction. It was a lifeline.
Trucks loaded with coca leaves and citrus fruits would squeeze past buses leaning so far over the edge that passengers would jump out of the windows in terror. Honestly, calling it a "road" is generous. It’s a ledge. Some parts are only 3 meters wide. That’s barely enough for one vehicle, yet for years, it handled two-way traffic. If you met another truck on a hairpin turn, someone had to back up. Usually, that meant backing up toward a 600-meter drop with no guardrails.
What Actually Makes the North Yungas Road So Deadly?
It’s not just the height.
The geography here is a nightmare for engineers. You start at the La Cumbre pass, roughly 4,650 meters above sea level. It’s freezing. There’s often snow. Then, as you descend toward Coroico, you drop into the Amazonian cloud forest. The temperature spikes, and the rain starts. This transition creates a constant thick fog that erases visibility in seconds.
You’ve got dust in the dry season and deep, sucking mud in the wet season. Waterfalls literally pour off the cliffs directly onto the road surface, turning the path into a slippery mess of rocks and slime.

In 1995, the Inter-American Development Bank officially named it the "World's Most Dangerous Road." They weren't exaggerating for clicks. Estimates suggest that before the new bypass was built, between 200 and 300 people died here every single year. You can see it in the landscape. Crosses. Hundreds of them. Small stone shrines called animitas mark the spots where trucks disappeared into the abyss.
The Local Logic: Driving on the Left
One of the weirdest things about la carrera de la muerte is the rules of the road. In Bolivia, people drive on the right. But on the Death Road? You drive on the left.
This sounds like a recipe for a head-on collision, but there’s a very practical, terrifying reason for it. A driver sitting on the left side of the vehicle (standard for Bolivian cars) needs to see exactly where their outer wheels are. By driving on the left—the cliffside—the driver can look out their window and see precisely how many inches of dirt are left before the fall.
Also, the downhill driver never has the right of way. The person coming up the mountain is usually hauling a massive load of goods and has less momentum. They get the "inside" track near the mountain wall, while the descending driver has to take the outer edge. It’s a high-stakes game of chicken that locals mastered over generations, though the rusted frames of buses at the bottom of the canyon suggest mastery had its limits.
From Transport Route to Extreme Tourism
In 2006, things changed. A modern, paved two-lane highway was finally completed, bypassing the most treacherous sections of the old road.

Most people thought the old North Yungas Road would just disappear back into the jungle. Instead, it became a bucket-list item for mountain bikers. Today, companies like Gravity Bolivia lead groups of adrenaline junkies down the path. You start in the thin air of the Andes and end up in the humid jungle, descending about 3,500 vertical meters in a single afternoon.
It’s a weird vibe. You’re on a high-end mountain bike with hydraulic disc brakes, wearing a full-face helmet, passing by those same crosses where families lost everything.
Is it still dangerous? Yes.
While the motorized traffic is mostly gone—aside from the occasional local motorbike or support van—the road itself is still decaying. Landslides are common. If you take a corner too fast on a bike, there’s still no guardrail to catch you. Since the tourist boom began, dozens of cyclists have lost their lives. Usually, it’s not because the road failed, but because the rider lost focus or tried to take a "cool" photo too close to the edge.
The 1983 Tragedy: A Dark Milestone
To understand why the "carrera de la muerte" name stuck, you have to look at July 24, 1983.

It remains the worst road accident in Bolivia’s history. A crowded bus veered off the road and tumbled into a canyon near San Pedro. More than 100 people died. There were almost no survivors. That single event cemented the road’s reputation globally. It wasn't just a difficult commute anymore; it was a national trauma.
Even today, locals speak about the road with a mix of respect and genuine fear. They don't see it as a "cool bike ride." For them, it represents a period of isolation where getting your crops to market meant gambling with your life every Tuesday.
Survival Tips and Reality Checks
If you’re actually planning to visit or ride la carrera de la muerte, stop thinking about it as a race. It’s an endurance test for your brakes and your nerves.
- Check the hardware: If you’re renting a bike, check the brake pads yourself. Don't take the guide’s word for it. Look for wear. Squeeze the levers. If they feel mushy, walk away.
- Layer up: You will start in a parka and end in a t-shirt. The temperature swing is brutal on the body.
- Watch the "Death Corners": There are specific turns, like the "Devil’s Curve," where the camber of the road actually slopes toward the cliff.
- Respect the fog: If the clouds roll in, stop. Wait. You cannot navigate a 3-meter ledge by memory.
The road is a graveyard. It’s also one of the most beautiful places on Earth. You’ll see the Amazon basin stretching out like a green sea from the top of the world. Just remember that the beauty is secondary to the physics of a thousand-foot drop.
Actionable Next Steps for Travelers
If you are heading to La Paz to tackle this, your first move shouldn't be booking a tour. It should be acclimatizing. Spend at least three days at altitude (La Paz is at 3,600m) before you even think about physical exertion.
Next, vet your tour operator through recent safety audits, not just TripAdvisor reviews. Ask specifically about their emergency evacuation plan. There are no helicopters waiting to pluck you off a ledge in the Yungas. If you go over, the rescue is a multi-hour manual operation by local firefighters.
Finally, ensure your travel insurance specifically covers "extreme sports" and "mountain biking on unpaved roads." Most standard policies have an exclusion clause for exactly this location. Check the fine print before you clip in.
