Discovering Koh Ker: A Step Back in Time

Our journey begins with a roughly 2-hour drive northeast of Siem Reap. Koh Ker isn’t as famous as Angkor, which is exactly what makes it appealing—fewer travelers mean more space for quiet contemplation and perfect photo opportunities. The highlight here is the seven-tiered pyramid, Prasat Thom, which rises dramatically from the jungle canopy. You can climb to the top, and honestly, the view of the surrounding forest and distant hills makes the effort worthwhile, offering a sense of achievement and a fantastic backdrop for photos.
The site covers over 40 smaller temples, scattered across the landscape, many adorned with elaborate carvings, stone guardians, and giant lingas. As Keith from the UK shared in the only review available, “the guide Poleak and the driver Chhun were great and should be commended.” His praise hints at how a knowledgeable guide can bring history alive, explaining the significance of the carvings and the layout of this once-important Khmer capital.
While Koh Ker’s remote location means some walking and climbing are involved, the experience feels exclusive and personal. The site isn’t overly restored, so you get a more authentic feel—imagine wandering among ruins that seem to whisper stories from nearly a thousand years ago.

Exploring Kulen National Park: Nature and Spirituality

After soaking up Koh Ker’s ancient mystique, the tour heads to Phnom Kulen, a lush, spiritually significant mountain about 50 km away. Known as the “Mountain of Lychees,” Kulen is famous for its scenic waterfalls, riverbed carvings, and large reclining Buddha at Preah Ang Thom. Here, you’ll spend roughly two hours exploring the area, which combines natural scenery with cultural relics.
The highlight for many is the River of a Thousand Lingas at Kbal Spean, where Hindu carvings are etched into the riverbed—something you wouldn’t want to miss if you’re into art, religion, or just stunning craftsmanship. The carvings depict deities and lingas, and walking along the riverbed offers a peaceful, almost meditative experience.
Preah Ang Thom, perched on a hilltop, features a massive reclining Buddha carved directly into the rock. Visitors often find this temple both humbling and inspiring, with sweeping views of the surrounding greenery. There’s also a chance to cool off at the waterfalls or even take a swim if you bring your swimwear, as some spots are designated for a quick dip, providing a refreshing break from the heat.
Practical Details and What to Expect

The tour kicks off with a pickup from your accommodation in Siem Reap. Expect a private, guided experience with an English-speaking guide, which often means personalized attention and the ability to ask questions freely. The total duration is around 7 hours, with the itinerary carefully planned to ensure you have enough time at each site without feeling rushed.
The drive between sites involves some time in the car, but it’s comfortable and scenic, giving you a chance to relax or ask your guide about local life and history. The tour includes photo stops, guided sightseeing, and walking, with some climbs involved, particularly at Koh Ker and Preah Ang Thom. Be prepared with comfortable shoes, sunscreen, insect repellent, and water.
At Kulen, bring swimwear if you want to enjoy the waterfalls or do some quick swimming. The site is a pilgrimage destination, so expect a peaceful, respectful atmosphere, especially at temples like Preah Ang Thom.
