Koh Ker Heritage Events: Responsible Visitor Guide

Koh Ker heritage events celebrate and interpret Cambodia’s remote former royal capital in Preah Vihear province. After Koh Ker was inscribed on the UNESCO World Heritage List in 2023, public attention to conservation, research and responsible tourism increased.

What events may take place

Programmes can include heritage talks, exhibitions, community performances, official ceremonies, student activities or tourism campaigns. These are occasional programmes rather than a guaranteed festival on one fixed September date.

About the archaeological site

Koh Ker served as a Khmer capital in the tenth century. Its temples and monumental landscape are spread across a large forested area, with Prasat Thom among the best-known structures.

Planning a responsible visit

• Use current official opening and ticket information.
• Stay on marked paths and never climb closed structures.
• Do not touch carvings or remove natural or archaeological material.
• Carry water and prepare for heat.
• Support local guides and services.

Confirming event dates

Check the National Authority for Preah Vihear, the Ministry of Culture and provincial announcements. A previous anniversary programme does not prove that the same event will repeat.
