Nakhon Pathom to Kampong Chhnang Road Trip Guide

The drive from Nakhon Pathom, Thailand, to Kampong Chhnang, Cambodia, crosses the Cardamom Mountains via the only international border crossing at Ban Laem (Thailand) / Daun Lem (Cambodia). This route is notable for its dramatic elevation change from the central Thai plains to the Cambodian lowlands, and it includes a stretch of National Road 5 that follows the Tonlé Sap River.

Covering approximately 450 kilometers, the trip typically takes 7 to 9 hours depending on border crossing time and road conditions. This guide covers everything from fuel costs to family amenities and hidden gems.

The route starts on Highway 4 (Phet Kasem Road) heading west from Nakhon Pathom, then turns south on Highway 344 to meet the border at Ban Laem. After crossing into Cambodia, continue on National Road 57 for 100 km to the junction with National Road 5, which leads to Kampong Chhnang.

Fuel stations are plentiful in Thailand but sparse in Cambodia, especially along NR 57. Plan to fill your tank at the last Thai station near the border.

• Border crossing: Ban Laem / Daun Lem, open 6:00–22:00.
• Vehicle insurance and permits required for Cambodia.
• Tolls on Thai highways are minimal; Cambodia has no toll roads.

The landscape transitions from flat rice paddies in Nakhon Pathom to the forested slopes of the Cardamom Mountains. As you descend into Cambodia, you'll see lush farmland and the floodplains of the Tonlé Sap.

Kampong Chhnang is known for its pottery and fishing villages, with many workshops along the river. You can also visit the Wat Kampong Tralach Leu, a Khmer temple dating from the 11th century.
