Siem Reap: Overland to Preah Vihear, Koh Ker temple

Discover Cambodia’s Hidden Temple Treasures with a Full-Day Overland Tour

If you’re craving an escape from the crowds around Angkor Wat, this overland day trip from Siem Reap offers an unforgettable journey to Preah Vihear and Koh Ker—two extraordinary Khmer temple sites that are less visited but equally spectacular. For about $110 per person, you’ll spend roughly 13 hours exploring ancient ruins perched atop mountains and sprawling complexes set among lush forests. Guided by knowledgeable locals, we love how this tour combines stunning vistas with authentic, off-the-beaten-path temples.

Two things stand out in particular: First, the chance to visit Preah Vihear, a temple built on a 525-meter cliff offering sweeping views of the surrounding forest and villages. Second, the adventure of exploring Koh Ker, once a Khmer capital, with its iconic 30-meter pyramid-shaped Prasat Thom looming above the plain. The tour’s small group setting and the flexibility to bring your own breakfast or lunch along make this an intimate, relaxed way to see Cambodia’s lesser-known but equally impressive ruins. The only consideration? This is a long day with early starts and some bumpy rides—so it’s best suited for energetic travelers ready for a full day of exploration.

This tour is perfect if you love adventure, are fascinated by ancient architecture, or want a more authentic experience away from the tourist crowds. It’s especially popular among travelers who appreciate knowledgeable guides and scenic views that stretch for miles. If you’re eager for a unique perspective on Khmer history and don’t mind a full day on the road, this trip is a superb choice.

An In-Depth Look at the Itinerary

Preah Vihear Temple

The day kicks off early at 5:00 am with hotel pickup, a smart choice to beat the heat and crowds. This UNESCO-listed site sits atop a 525-meter cliff in the Dangrek Mountains, straddling the border of Cambodia and Thailand. The view from the top is a highlight—vast forests and villages sprawled beneath you, giving a real sense of Khmer grandeur. Built during the 9th and 10th centuries, the temple was awarded to Cambodia after a lengthy dispute with Thailand, underscoring its importance.

We loved the way the guide explained the history and significance of the site—adding context to the impressive stonework. Keep in mind, admission fees aren’t included, so you’ll want to budget for those. The climb up involves a truck ride (a 4×4 pickup), which adds a bit of adventure before the final ascent.

Koh Ker Temple Group

Next, heading northeast, the tour takes you to Koh Ker, the temporary Khmer capital between 928-944 AD. This site is a sprawling complex with dozens of temples, but the star is Prasat Thom, a towering 30-meter pyramid-shaped structure. Walking through the ruins, you’ll encounter numerous smaller temples and sculptures, remnants of the once-powerful city.

Reviews note how off the beaten path this site is—”minimally touristed” and best for explorers. We appreciated the sense of discovery and the chance to see a lesser-known part of Khmer history, far from the crowds of Angkor.

Smaller Temples: Prasat Linga 1 & Kraham

The tour continues with visits to Prasat Linga 1 or Thnoeng, and Prasat Kraham, both offering a quiet glimpse into Khmer religious architecture. These smaller sites, set among plains and forests, afford a tranquil atmosphere and a chance to appreciate intricate stone carvings and the ambience of remote ruins.

Prasat Krachap

Lastly, Prasat Krachap provides a broader view of Koh Ker’s secondary monuments, with its curious mixture of structures. It’s a good point to reflect on the scope of Khmer engineering and the complexity of these ancient complexes.

Optional Visit: Angkor Pass

If your Angkor Pass is still valid, there’s a chance to visit some of these sites as part of your regular Angkor itinerary, though most prefer to see the remote temples separately to avoid overloading their day.

Practical Details and What to Expect

Transportation

You’ll start with hotel pickup, then ride in a private vehicle—convenient and comfortable for the long trip. The highlight is the truck climb up to Preah Vihear, adding a bit of excitement to your ascent.

Timing

The early start at 5:00 am means you’ll beat most of the heat and enjoy cooler weather and fewer crowds at Preah Vihear. The tour lasts roughly 13 hours, ending back at your hotel, so prepare for a full day of walking, exploring, and scenic drives.

Guides and Group Size

The tour is private, so only your group participates—an advantage for tailored questions and a more relaxed pace. Guides like Ty are praised for their knowledge and friendly manner, making the history come alive.

One reviewer called it a “channel to Laura Croft,” highlighting the adventure and discovery aspect. Another noted how rare it is to visit such remote temples with almost no other travelers around, making the experience feel like a true explorer’s quest.
