Introduction
The drive from Phnom Penh to Kampong Thom follows National Highway 6 (NH6), a 168-kilometer route that typically takes 2.5 to 3 hours by car. The road was upgraded in 2015, and its flat, straight blacktop offers a swift journey through Cambodia's central plains.
Kampong Thom is known for the prehistoric site of Samrong Sen, a significant Bronze Age settlement. En route, the highway crosses the Tonle Sap floodplain, where the annual monsoon transforms the landscape into a patchwork of rice paddies and lotus fields.

Natural Landscapes and Local Commerce
Skun, a town halfway, is famous for its deep-fried spiders and other exotic snacks. The local commerce here thrives on travelers, offering a unique culinary stop. Further north, the landscape becomes dotted with palm trees and traditional stilt houses.
Kampong Thom city itself is a gateway to the pre-Angkorian temple complex of Sambor Prei Kuk, a UNESCO World Heritage Site. The site features over 100 temples predating Angkor Wat by 200 years, set amidst forested ruins.
Road Safety, Family Stops, and Fatigue Management
Road safety is generally adequate, but watch for motorbikes, livestock, and sudden crossings. The route is fairly straight, which can induce fatigue; plan to stop every hour or so. Rest areas are simple but sufficient for stretching and refreshments.
For families, the Skun market is a curious stop for older children, but beware of food safety. Pet-friendly stops are few, but roadside eateries with open air seating often welcome well-behaved pets.
Hidden off-route spots include the two-armed Tonle Sap fishing villages near the highway, accessible by short dirt tracks. Take caution in the wet season as these tracks can be muddy.
Route Logistics and Infrastructure
NH6 is a two-lane road with occasional paved shoulders. In dry season (Nov-Apr), travel is smooth; in wet season (May-Oct), expect potholes and flooding at low spots. Road lighting is minimal outside urban areas, so night driving is not recommended.
- Fuel stations: Plenty along the route, with larger stations in Skun and Kampong Thom. Prices are similar to Phnom Penh.
- Tolls: None on this highway.
- Rest stops: Several roadside cafes and food stalls, especially at the Skun insect market.
