Archaeologists Discovered Unknown Machu Picchu Roads
Researchers uncovered over a mile of previously hidden paths along the slopes of Mount Yanantin.
Updated on Sept. 30, 2026 in Geography
Archaeologists have identified more than 1.5 miles of unknown roads hidden within the dense forest canopy of the Machu Picchu National Archaeological Park. The discovery, situated on the slopes of Mount Yanantin, was made using advanced mapping technology to survey the rugged Andean terrain.
Why it matters
Mapping these forgotten routes provides critical insight into the complex transportation networks of the region, helping researchers better understand how ancient civilizations traversed these high-altitude landscapes. The discovery underscores the effectiveness of modern scanning tools in locating significant historical infrastructure that remains obscured by dense vegetation.
The newly found pathways span across altitudes ranging from 6,500 to 8,860 feet above sea level. Researchers utilized Light Detection and Ranging (LiDAR) via drone-mounted lasers to digitally penetrate the forest canopy and map the terrain.
The players
Machu Picchu National Archaeological Park
This protected area serves as the primary governing institution for the preservation and study of the historical site in Peru.
Mount Yanantin
This mountain features the slopes where the recent archaeological discovery of hidden road segments took place.
The details
By firing laser pulses at the ground, the LiDAR technology allowed researchers to strip away the dense forest cover and reveal the underlying structural path. This survey work builds upon earlier reconnaissance efforts centered near the site of the Mandor wall.

The Big Picture
The discovery of these road segments significantly updates the historical site map previously established by the Machu Picchu National Archaeological Park research protocols. This finding shifts the scientific understanding of regional connectivity and challenges previous assumptions about the reach of ancient trail networks.
This discovery offers new potential for future archaeological tourism as officials determine if these paths can be safely integrated into existing park trails. It also demonstrates how advanced mapping technology is rapidly changing the feasibility of exploring remote or protected natural heritage sites.
The takeaway
These findings highlight how non-invasive scanning technology is essential for uncovering historical sites hidden in inaccessible terrain. Enthusiasts can monitor updates from regional archaeological authorities to see if these paths will become accessible for future academic study or public viewing.
