An Authentic Day of Khmer Wonders: Preah Vihear, Koh Ker & More

If you’re craving a full-day adventure that takes you beyond the crowds of Angkor Wat and into the lesser-visited but equally spectacular temples of Cambodia, this small-group tour is a fantastic choice. For around $100, you get to explore Preah Vihear temple, perched atop a 700-meter-high cliff, then head to Koh Ker, home to a striking pyramid-shaped temple and other archaeological gems. With a maximum of just six travelers, it promises a more intimate, flexible experience—ideal if you prefer a personal touch over large tour buses.
Two things really stand out: the knowledgeable guide, Dara, who brings history alive with stories and insights, and the spectacular views from Preah Vihear’s lofty perch.

It’s a long day with quite a bit of driving, so if comfort or travel fatigue is a concern, be prepared.

Exploring Cambodia’s Hidden Temples: A Deep Dive

When we think of Cambodia’s temples, Angkor Wat often steals the spotlight. But this tour offers a chance to step off the beaten path and see some lesser-known yet equally captivating sites.
Starting with Preah Vihear: A Clifftop Marvel
Your day begins early, with pickup from your Siem Reap hotel around 7 AM. The highlight here is Preah Vihear, a UNESCO World Heritage site perched atop a 700-meter-high cliff on the border with Thailand. The journey includes a scenic drive followed by an exciting 4×4 ride up the hill—an exhilarating way to start the adventure. As you ascend, the landscape opens up to sweeping views, and you’ll quickly grasp why this site is so revered.
The temple’s positioning on the cliff’s edge makes it not only a feat of ancient architecture but also an ideal spot for photography and appreciating Cambodia’s natural beauty. The intricate carvings and stonework reflect the craftsmanship of Khmer artisans. Expect to spend about two hours exploring the site, taking in the panoramic vistas that stretch beyond the horizon.
Reviews highlight the impact of this stop, with one traveler noting the “stunning surroundings” and the way the guide, Ra, made the history come alive. The ascent, while a moderate hike, is manageable for most, and the optional 4×4 ride adds a dash of adventure.
Koh Ker: The Pyramid of Cambodia
After descending from Preah Vihear, your journey continues to Koh Ker, an ancient city once used as a royal capital during the Khmer Empire. The highlight here is the pyramid-shaped temple, which stands out dramatically against the jungle backdrop. Think of it as Cambodia’s own step pyramid, with intricate carvings and a surprisingly well-preserved structure.
The complex also includes other temples and structures, such as Prasat Linga 1 & 2, Kraham, and Prasat Pram, each with its own story. You’ll love the way these ruins are scattered and the sense of discovering ancient secrets. For instance, Prasat Pram, with its five towers, is remarkably restored and offers a stunning view of what remains.
Traveler testimonials praise the detail in the carvings and the chance to wander through a site less crowded than Angkor, giving a more authentic and relaxed experience. You’ll spend around two hours here, exploring the different temples and soaking in the jungle atmosphere.
Hidden Temples: Prasat Kraham, Linga 4, and Prasat Pram
Within Koh Ker’s sprawling complex, a few sites stand out:
- Prasat Kraham: A worship site still favored by local villagers, this temple offers a glimpse of ongoing local religious practices. It’s an important site for understanding how these ruins still play a role in community life.
- Prasat Linga 4 (Andong Kuk): Surrounded by jungle for over a millennium, this site features an impressive Linga, a symbol of Shiva, in good condition despite the ruins. Stepping into this temple feels like entering a world frozen in time.
- Prasat Pram: This is perhaps the most photogenic of the lot, with the five restored towers giving a dramatic silhouette in the jungle.
