Phan Rang–Thap Cham to Kampong Chhnang: Road Trip Guide

The route from Phan Rang–Thap Cham to Kampong Chhnang is 450 km long, crossing the Central Highlands and the Mekong Delta before entering Cambodia. It's a drive that rewards those who plan for long distances and diverse terrain.

Before setting out, note that the shortest path uses QL1 (National Road 1) in Vietnam and NR1 in Cambodia, but the scenic alternative through Dalat and Buon Ma Thuot adds 60 km but offers mountain views.

Checkpoints require a valid passport and vehicle import documents; the Moc Bai border crossing is the busiest, but the Le Thanh border near Pleiku can save time.

• Fuel prices vary: diesel costs around VND 22,000/liter in Vietnam and $1.10/liter in Cambodia, so fill up before crossing.
• Road tolls total approximately VND 300,000 on QL1; the Dalat route has no tolls but winding roads.
• Most petrol stations are along QL1, but on the Dalat route, stations are sparse between towns; plan fuel stops.

You'll pass through three distinct ecosystems: the arid coast of Phan Rang, the pine forests and waterfalls around Dalat, and the rubber plantations and rice paddies of Cambodia. The latter part of the drive is flat and green.

Hun Sen Road in Kampong Chhnang is lined with pottery workshops, a local craft that dates back to the 8th century. You can watch artisans shape clay into jars and buy directly from them.

Near the border, the village of Banlung is a base for exploring the Yeak Laom volcanic lake, a crater lake with crystal-clear water surrounded by jungle.

Most of the route is paved two-lane road, but the Dalat mountain pass has sharp curves, and Cambodian roads may have potholes or temporary detours. Drive defensively at all times.

• Family-friendly stops include the Pongour Waterfall near Dalat, where there are shallow pools for kids, and the Kampong Chhnang riverside park with playgrounds.
• Pet-friendly accommodation along the way includes certain homestays in Dalat and Banlung; always confirm in advance.
• Rest breaks are essential: every two hours, stop at designated rest areas or major towns like Buon Ma Thuot and Kratie.
