Pleiku to Kampong Chhnang Road Trip Guide

This route begins in Pleiku, Vietnam, at 784 meters above sea level, and ends in Kampong Chhnang, Cambodia, on the banks of the Tonle Sap River. The drive covers approximately 500 kilometers, with the border crossing at Le Thanh/O Yadav. As you descend from the volcanic plateaus of the Central Highlands to the flat alluvial plains of the Mekong Delta, the climate shifts from a temperate highland zone to a tropical monsoon region.

The route transitions from the pine forests and red basalt soils of Pleiku to the rubber and cashew plantations of eastern Cambodia. As you approach Kampong Chhnang, the landscape flattens into rice paddies and the iconic Tonle Sap floodplain. The region is known for its pottery villages near Kampong Chhnang town, where you can watch artisans at work.

Local commerce varies with the terrain. In Vietnam, roadside stalls sell passionfruit and avocado smoothies; in Cambodia, look for fresh palm sugar and Kampot pepper. For a break, the town of Snuol is a hub for timber trade, though it's not a major tourist stop.

UNESCO sites are not directly on the route, but the temple ruins of Sambor Prei Kuk, a UNESCO World Heritage Site, are a 60-kilometer detour from Kampong Thom on NH6. Allow an extra half-day to explore this 7th-century pre-Angkorian complex.

Driving conditions vary: in Vietnam, expect heavy traffic on NH19 near Pleiku; in Cambodia, NH6 is busy with trucks but manageable. Watch for livestock and motorbikes on rural stretches. Always carry your passport and vehicle registration.

• Rest stops with clean facilities are available every 50-80 km on NH6; in Vietnam, roadside coffee shops are frequent.
• For families: The Cambodian Cultural Village in Siem Reap is off-route, but closer, the Kampong Chhnang pottery village offers easy, child-friendly activities.
• Pet-friendly: Most roadside stops are family-run and allow pets, but keep your pet on a leash.

Fatigue management: Plan to stop every 2-3 hours. A good layover is the town of Kampong Thom, roughly halfway, with several guesthouses and restaurants. For a unique view, stop at the Snuol petrol station, where you can see the deforested hills - a sobering reminder of environmental change.

Hidden spots: About 20 km before Kampong Chhnang, turn left at the sign for Oudong, an ancient royal city with hilltop stupas and panoramic views. This detour is unmarked but safe.

National Road 19 in Vietnam connects Pleiku to the Le Thanh border crossing. On the Cambodian side, National Road 7 runs from O Yadav to Snuol, then National Road 6 continues to Kampong Chhnang via Kampong Thom. The total driving time is 9 to 10 hours, excluding border formalities.

• Fuel costs differ: In Vietnam, gasoline is about 25,000 VND/liter; in Cambodia, around 4,500 KHR/liter (as of mid-2024).
• Border crossing hours: Le Thanh/O Yadav is open daily from 7:00 to 17:00 (Vietnam time; Cambodia is an hour behind).
• Currency exchange: Change money at the border for better rates; US dollars are widely accepted in Cambodia.

Road quality is generally good on both highways, but expect potholes in Cambodia after the rainy season. Tolls apply on Vietnamese highways; NH7 and NH6 have no tolls.
