Hotel pick up at 7:45 am to 8:00 am by tour guide and driver.

It is a 12th century Hindu temple located next to the canal used to transport sandstone from the quarries of Phnom Kulen to Angkor Wat.

Koh Ker is a 10th-century temple complex in the north Cambodian jungle. A former capital of the Khmer Empire, the site is now remote and heavily forested. The main structure, Koh Ker Temple, is a stepped 7-tiered pyramid. The large rectangular tank, Rahal Baray, supplied water to the complex. The Prasat Krahom, meaning "red temple," is known for its sandstone carvings, while Prasat Pram is covered in strangler figs.

Koh Ker is a remote archaeological site in northern Cambodia about 120 kilometres (75 mi) away from Siem Reap and the ancient site of Angkor.

The square shrine, monolithic in scale, shares its layout and likely its purpose with 3 more that are aligned on a north-south axis whilst having a relationship with the east-west axis of Prasat Thom. None of these gigantic linga shrines have roofs, perhaps unfinished, or made from perishable materials and lost to time. They all feature a sandstone base with steps on each side leading to false.

A site consisting of originally three brick towers.

One of the larger of the secondary monuments at Koh Ker, Prast Krachap has a similar position, east of the Rahal, and a similar curious mixture.

Return to hotel and driver around 60 minutes to arrive Siem Reap.
