Da Nang to Prey Veng Road Trip: Time, Stops & Logistics

The Da Nang to Prey Veng drive is a 720 km journey that crosses Vietnam's central highlands and the Cambodian lowlands. One of the most unusual border crossings is at Hoa Lu, where the Vietnamese side is a bustling market town and the Cambodian side is a quiet checkpoint. The two countries use different traffic rules: Vietnam drives on the right, Cambodia on the right, but Cambodian rural roads often have no lane markings.

Vietnam's central highlands are volcanic, with red basaltic soils supporting coffee and pepper plantations. As you descend into Cambodia, the landscape shifts to dry deciduous forests and cashew orchards. Ban Lung is home to the Yeak Laom volcanic lake, a perfect swimming spot, and the Ka Chanh waterfall. In Prey Veng, the Mekong river is the lifeblood; the town's riverside market is a hub for traders.

UNESCO World Heritage Sites near the route include the My Son Sanctuary (off QL1A near Hoi An, a 30-minute detour), and, if you detour 150 km south from Phnom Penh, the Templo de Preah Vihear (though that adds 4 hours). The Dong Xuan market in Da Nang is the best place to stock up on Vietnamese coffee and dried seafood. In Cambodia, Kampong Cham's French-colonial architecture is a highlight.

Road safety varies: Vietnam's QL14 is well-maintained but hilly; Cambodia's NR7 is flat but has frequent livestock crossings and poor lighting at dusk. Drive during daylight hours, and use rest stops every two hours. Recommended family-friendly stops include the Taman Safari Indonesia-style zoo in Buon Ma Thuot (off QL14) and the Kratie dolphin pool on the Mekong. For kids, the Hoi An Ancient Town (near Da Nang) is a cultural break, but it's a detour of 30 km.

Pet-friendly framework: most Vietnamese hotels allow pets with a fee ($5-10), but in Cambodia, only a few guesthouses in Ban Lung and Phnom Penh accept them. The highway rest areas in Vietnam have clean toilets and small cafés; in Cambodia, use roadside restaurants. Fatigue management: the steepest climbs are between Da Nang and Pleiku; the most monotonous stretch is the straight, flat road from Kampong Cham to Prey Veng. Plan overnight stops at Pleiku and Ban Lung to split the drive into three manageable days.

You'll spend about 15 hours behind the wheel, excluding border and rest stops. The route uses Vietnam's QL1A, QL14, and QL19, then Cambodia's NR7 and NR1. Fuel stations are frequent in Vietnam (every 30-50 km), but in Cambodia's Ratanakiri province, they become scarce (every 80-100 km). As of 2025, gasoline costs about 25,000 VND/liter in Vietnam and 4,200 KHR/liter in Cambodia; the 720 km trip will consume roughly 60 liters, costing around 1.5 million VND or 250 USD.

Border crossing at Hoa Lu (Vietnam) / O'Yadav (Cambodia): open 7 AM to 5 PM. You'll need a valid passport with at least 6 months validity and a Cambodian e-visa (available online for $30). Vietnamese vehicle insurance is mandatory, but Cambodian insurance can be purchased at the border for about $10. The roads are largely two-lane, with potholes in sections near the border.Mobile data: Vietnam's Viettel works well in the highlands, but coverage drops in Cambodia's Mondulkiri; buy a Smart Axiata SIM in Ban Lung.
