Why You’ll Love This Tour

This tour hits the sweet spot for travelers seeking meaningful encounters with Cambodia’s past. You’ll get a feel for the birthplace of the Khmer Empire at Phnom Kulen, where carved lingas in the river and Vishnu sculptures make history tangible. We loved the way our guide explained the significance of each carving, weaving mythology and local beliefs into the narrative.
Then, heading to Koh Ker, you’ll explore the abandoned 10th-century capital, a site that feels like stepping into a lost civilization. The 10th-century ruins, including the impressive pyramid-shaped temple, give you a sense of how the Khmer Empire once expanded beyond Angkor.
The tour’s private setup is especially valuable because it allows for a more relaxed experience, with your guide tending to your questions and pace. Based on reviews, guides tend to be both knowledgeable and attentive, making the experience more engaging and insightful.
A notable highlight is the visit to the River of a Thousand Lingas, carved into the riverbed, which visitors often find both beautiful and mystical. Its water is believed to have magical properties, adding a spiritual dimension to the walk along the river.
One possible drawback is the terrain; some steep paths and uneven ground at Phnom Kulen mean comfortable footwear is essential. Also, the car used might not be the most robust for rough mountain roads, according to one reviewer’s suggestion for a sturdier vehicle.
This tour suits those interested in Cambodia’s ancient history, Hindu and Buddhist symbolism, and off-the-beaten-path adventures. It’s perfect for travelers who want a deeper, more authentic look at Cambodia beyond the temples of Angkor.

In-Depth: What You Can Expect

Phnom Kulen: The Sacred Mountain
Your day begins with a pickup from your Siem Reap hotel, followed by a scenic drive northeast to Phnom Kulen National Park. This area is revered both spiritually and historically — a place that served as a significant starting point for the Khmer Empire.
The first stop is the River of a Thousand Lingas (Sahasralinga). Carved into the riverbed, these lingas are symbols of Shiva, some accompanied by yoni carvings representing fertility and creation. Visitors often find this site almost magical, with the water passing over the carvings believed to hold special powers. An reviewer from Singapore shared, “I enjoyed this trip as it was exactly what I wanted — the carvings are surprisingly well-preserved under the water, and the guide explained their mythological significance clearly.”
Next, you’ll see impressive stone carvings of deities such as Vishnu reclining on the cosmic ocean, Brahma emerging from Vishnu’s navel atop a lotus, and various Hindu mythological scenes. These add a spiritual layer to the landscape, showing the historical transition from Hinduism to Buddhism at the site.
The Reclining Buddha is another highlight. Carved from natural stone in the 16th century, this figure reflects Buddhist influence and offers a peaceful visual contrast to the Hindu carvings.
After these cultural stops, the tour takes you to Kulen Waterfall, where the scenery shifts to lush greenery and the sound of cascading water. You’ll have time to relax, enjoy the cool mist, and even take a swim — a refreshing break after the uphill walk.
Koh Ker: The Forgotten Capital
After a hearty lunch (often included or recommended at a local spot), the journey continues to the abandoned Koh Ker complex, located about 100 km from Angkor. This site was the Khmer Empire’s capital briefly between 928 and 944 AD, during a turbulent period for the empire.
Koh Ker’s main attraction is its giant pyramid-shaped temple, Prasat Thom, which rivals Angkor Wat in scale but offers a different, more intimate experience due to its isolated location. Climbing to the top rewards visitors with panoramic views of the surrounding jungle and ruins, giving you a sense of what it must have felt like to be at the heart of an ancient city.
The ruins at Koh Ker include numerous smaller temples, statues, and carved stones, many covered in moss and jungle growth. It’s a site that invites exploration and imagination, perfect for history buffs or those who love discovering Cambodia’s lesser-known sites.
