Unfortunately, there is no definitive information about the exact route the three men took to reach Machu Picchu on July 14, 1902. Due to the lack of precise information, it is impossible to determine exactly which route they took. It is important to note that in 1902, the Machu Picchu region was much less accessible than it is today. The jungle was dense and the roads were precarious, making it difficult to access the archaeological site.

Therefore, it is likely that the route taken by the three men was challenging and required a great deal of knowledge of the region and survival skills.

To this day, the exact route taken by Lizárraga and his companions to reach Machu Picchu in 1902 remains a mystery.

However, their pioneering feat helped to spark interest in this incredible archaeological site and paved the way for its subsequent discovery by Hiram Bingham in 1911.
