Kampong Thom to Stung Treng: Road Trip Guide, Stops, & Tips

The drive from Kampong Thom to Stung Treng follows National Road 6 (NR6) for about 190 kilometers, a route that traces the Sen River and gradually shifts from Cambodia's central lowlands to the edge of the northeastern highlands. The road itself is part of the historic 'Royal Route' that once connected Angkor to the Lao border, and you'll notice the landscape transition from rice paddies to rubber plantations as you approach Stung Treng.

Before heading out, check road conditions: NR6 is generally paved and in good condition, but sections after Kratie province turn can have potholes. The route is open year-round, but the rainy season (May–October) brings heavier traffic and possible flooding near causeways.
