Koh Ker: Cambodia's Lost Pyramid City
New UNESCO World Heritage Site (2023)
120 km NE of Siem Reap (2.5 hrs).
$15 USD (Separate from Angkor Pass).
Moderate (Stairs to pyramid).
Deep in the jungles of Preah Vihear province lies a place of myth and legend: Koh Ker. For a brief, brilliant period in the 10th century, this was the capital of the mighty Khmer Empire. Now officially a UNESCO World Heritage site, it offers a remote, Indiana Jones-style adventure far from the crowds of Angkor Wat.
The "Mayan" Pyramid of Cambodia
Prasat Thom (The Pyramid)
The undisputed centerpiece of Koh Ker is Prasat Thom. This seven-tiered sandstone pyramid stands 36 meters tall and looks strikingly similar to Mayan temples found in South America. Thanks to a sturdy wooden staircase, you can now safely climb to the very top for a breathtaking 360-degree view over the unbroken jungle canopy.
The Satellite Temples
Beyond the pyramid, a loop road takes you past dozens of smaller ruins. Don't miss Prasat Pram, where strangler figs have completely wrapped around the red brick towers, creating a scene that rivals Ta Prohm. While this area was once a conflict zone, it has been de-mined. Always stay on the marked paths.
💡 Perfect Day Trip Combo
Since Koh Ker is a long drive (2.5 hours), most travelers combine it with Beng Mealea, the famous "Jungle Temple." Do Beng Mealea in the morning, have lunch, and then hit Koh Ker in the afternoon.
Need a Driver?
This remote adventure requires a private car or taxi, as tuk-tuks are too slow for the distance. We can help you arrange a reliable driver for the day.
