The Punta Olympic Tunnel in Peru was built at 4,738 meters above sea level, cutting through the White Mountains in the Andes, with a length of 1,384 meters, and the AN-107 highway leading to the tunnel reaches 4,818 meters, making it the highest paved road in the world within the Huascarán National Park.
There is a place in the Peruvian Andes where human engineering has cut through the mountain at almost five thousand meters above sea level to connect two valleys that were previously separated by hours of dirt road. The Punta Olympic Tunnel is a work that crosses the White Mountains in Peru at 4,738 meters above sea level, connecting the regions of Carhuaz and Chacas amidst landscapes that seem otherworldly. The highway leading to the tunnel reaches 4,818 meters just before the entrance of the tunnel, ensuring the title of the highest paved road in the entire world.
The tunnel is 1,384 meters long and 7.20 meters wide, inaugurated in 2013 as part of the AN-107 highway within the Huascarán National Park. Before the construction of the tunnel, crossing these mountains was a dangerous task that took many hours on dirt roads with sharp turns. The completion of the project drastically reduced travel time between the valleys, facilitated trade, and improved access to healthcare services for the communities of Chacas and the surrounding area. What was once an insurmountable geographical barrier has transformed into a crossing that ordinary cars can navigate.
The numbers that make the Punta Olympic Tunnel an impressive work in the Andes
The dimensions and location of the tunnel place the work among the most extreme engineering feats in the world. The tunnel is at 4,738 meters above sea level, has a length of 1,384 meters, and the lane is 7.20 meters wide, sufficient for traffic in both directions with flow control.

The largest pulp factory in the world is being built in Brazil for R$ 23 billion and promises 14,000 jobs; see how the construction is progressing, which will have 3.5 million tons/year, 400 MW of clean energy, and 400,000 hectares of eucalyptus.
The project was an investment by the regional government of Ancash that cost around R$ 500 million at the time, according to data from the Ministry of Transport and Communications of Peru.
The internal structure of the tunnel features modern lighting and ventilation systems to ensure the safety of drivers crossing through the rock at an altitude where the available oxygen is significantly lower than at sea level.
The high-quality paving of the highway allows ordinary vehicles to reach the summit, as long as the driver is prepared to deal with the thin air and temperatures that can drop below zero even during the day.
What can be found on the highway leading to the highest tunnel in the world
The AN-107 highway is not just a road. It is a route that crosses landscapes that most people only see in documentaries.
The road to the tunnel passes by snow-capped peaks such as Contrahierbas and Huascarán, the highest point in Peru at over 6,700 meters, as well as waterfalls fed by melting snow and high-altitude lagoons that reflect the Andean sky with a clarity impossible at lower altitudes.
The winding curves of the highway are paved in conditions that are surprising for the altitude and extreme climate of the region. The asphalt remains intact thanks to constant maintenance that prevents blockages from snow or landslides, common in the Andean winter.
The traffic of heavy trucks is controlled, making the ascent smoother for smaller vehicles. For cyclists and high-displacement motorcyclists, the road leading to the tunnel is one of the most challenging and sought-after routes on the continent.
What is the experience of driving at almost five thousand meters towards the tunnel
Driving at 4,818 meters above sea level requires extra care with the vehicle’s engine and one’s own body. The thin air reduces the power of combustion engines and causes the famous soroche, altitude sickness, which causes headaches, nausea, and shortness of breath.
The recommendation for those facing the ascent to the tunnel is to go up slowly, maintain constant hydration, and, if possible, spend one or two days in Huaraz for acclimatization before attempting the full route.
At the highest point of the highway, just before the entrance to the tunnel, the wind blows strongly and the surrounding scenery is dominated by rock, ice, and sky. The feeling of being almost five kilometers above sea level on a paved road is hard to describe for those who have never experienced it.
The cold air cuts across the face, breathing is short, and the silence of the mountains is interrupted only by the wind and the vehicle’s engine. For photographers, stopping at the shelters near the entrance of the tunnel yields images of glaciers that do not exist anywhere else accessible by asphalt.
The importance of the tunnel for the communities living on both sides of the mountain
The social impact of the work goes far beyond tourism. Before the tunnel, the communities of Chacas and the surrounding area depended on precarious roads that became impassable during the winter, cutting off access to hospitals, markets, and public services for weeks.
The crossing between the valleys that today takes only a few hours by car used to consume an entire day under poor conditions, with a real risk of accidents on unpaved roads without side protection.
With the inauguration of the tunnel in 2013, trade between the regions intensified and access to healthcare services improved measurably. Agricultural products that previously lost value due to transportation time now arrive fresh at the markets of the opposite valley.
Patients needing hospital care in Carhuaz or Huaraz no longer depend on weather conditions to cross the mountain. The tunnel transformed geography from an obstacle into a passage, and the lives of people who depended on this crossing changed permanently.
Why the Punta Olympic Tunnel attracts travelers from around the world
In addition to its logistical and social function, the tunnel has become a must-visit tourist spot for those visiting Huaraz and the Huascarán National Park. The combination of extreme engineering, record altitude, and Andean landscape transforms the crossing into an experience that travelers from all over the world seek.
Cyclists traversing the Andes include the ascent to the tunnel as one of the most emblematic stretches on the continent, and motorcyclists plan entire routes around the passage via the AN-107 highway.
The Punta Olympic Tunnel is proof that human technology can overcome extreme geographical barriers when there is planning and investment. Building a paved passage at almost five thousand meters above sea level, with lighting, ventilation, and constant maintenance, is an achievement that places Peru on the map of world engineering.
And for those driving there, what stays in memory is not just the tunnel itself, but the entire journey of climbing so high on a road that shouldn’t exist.
Would you take the drive up to the highest tunnel in the world, or do you think 4,818 meters above sea level is too much? Have you visited the Andes or dream of knowing them? Let us know in the comments. Engineering works in extreme places fascinate precisely because they show what happens when human will faces the mountain.
