Koh Ker sits about 120 kilometers from Siem Reap, and most visits take 2.5 to 3 hours by road each way. The site opens daily from 7:30 AM to 5:30 PM, and the main draw is Prasat Thom, a seven tier pyramid that rises 36 meters above the forest floor. Koh Ker was the Khmer capital from 928 to 944 CE, and the wider archaeological zone spreads across 35 square kilometers with more than 180 structures.
Wear closed shoes for the pyramid stairs and light clothes that cover shoulders and knees.
Bring cash, sun cream, and water for the long day.
Koh Ker has a separate entry ticket, and ASEAN ANGKOR GUIDE currently lists the fee at USD 15 per adult.
The Angkor Pass does not cover Koh Ker.
Use our Koh Ker entrance fee guide and Koh Ker temple map guide before your visit.
At ASEAN ANGKOR GUIDE, we shape Koh Ker around your time, pace, and temple goals. For most guests, the best all round option is a small group day trip that pairs Koh Ker Pyramid Temple with Beng Mealea and Banteay Srei in one smooth plan.
Book the Banteay Srei Beng Mealea and Koh Ker small group tour for hotel pickup, air conditioned transport, lunch, and a guided full day from Siem Reap.
Choose the Full-Day Preah Vihear Koh Ker and Beng Mealea Tour if you want a longer private day with more space and a bigger temple mix.
Read our Koh Ker temple in Cambodia guide first if you plan to go on your own and want the route, opening hours, and site basics in one place.
The easiest way to reach Koh Ker is to leave from Siem Reap early and travel by private car or guided tour. The road run is about 120 kilometers, and the usual drive time is 2.5 to 3 hours.
Small group tour: a smart fit if you want lower cost, hotel pickup, lunch, and a full temple day already mapped out.
Private tour: better if you want more room, photo stops, and control over your pace.
Independent car: possible, though most first time visitors get more from Koh Ker with a guide who can tie the pyramid, the old capital, and the side temples into one clear story.
For route planning and ticket setup, pair our Angkor Wat entrance ticket guide with the Koh Ker temple in Cambodia guide.
Koh Ker is easiest to enjoy from November to February, when mornings are cooler and the pyramid climb feels much lighter. We like early starts because the light is cleaner and the stairs are more comfortable before midday heat sets in.
November to February: best road and weather window, with cooler mornings around 20 to 25 degrees Celsius.
March to May: hotter days, often 35 to 40 degrees Celsius, but fewer people on site.
June to October: greener scenery and a fuller reservoir, though rain can make the stairs slick.
Aim to arrive between 7:30 AM and 9:00 AM for the strongest balance of light and comfort.
Koh Ker was the Khmer capital from 928 to 944 CE under Jayavarman IV, and today it stands out for its seven tier Prasat Thom pyramid, its broad archaeological zone, and its UNESCO listing from 2023.
Koh Ker is about 120 kilometers from Siem Reap, with a road time of roughly 2.5 to 3 hours. You can go by small group tour, private tour, or private car, though most travelers prefer a guided run for easier timing and a fuller temple day.
Yes. If you want one day that feels quieter than the main Angkor circuit and still gives you a major temple payoff, Koh Ker is well worth the early start. The pyramid climb alone gives the trip a very different feel from the flat temple routes closer to town.
The current ASEAN ANGKOR GUIDE price is USD 15 per adult for single day entry. Children under 12 enter free. Bring cash or card and keep your ticket with you once inside.
No. Koh Ker needs its own separate ticket even if you already hold an Angkor Pass. If you are also visiting Angkor, buy each ticket for its own site plan so your day runs cleanly from the start.
Start with Prasat Thom, the pyramid that gives Koh Ker its biggest wow moment and the best elevated view across the forest. Add Prasat Pram for the root wrapped stonework that many travelers want in their photo set. Then make room for Prasat Chen, Prasat Krahom, and the Rahal reservoir if you want a fuller read on how this old capital was laid out. This mix gives you the big icon, the mood shots, and the wider story in one visit. At ASEAN ANGKOR GUIDE, that is the route we like most for a first Koh Ker day.
