Sa Dec to Kampong Chhnang Drive: Full Route Guide

The drive from Sa Dec to Kampong Chhnang crosses the Mekong Delta and the Cambodian border, a journey of ~330 km that typically takes 7–8 hours by car, including border formalities. Sa Dec, a riverside town in Vietnam's Đồng Tháp Province, is the hometown of writer Marguerite Duras, and the route follows National Route 80 to the border at Vĩnh Hường, then continues on Cambodian National Road 1 and 5 through Phnom Penh bypass.

Safety: In Cambodia, drive on the right – same as Vietnam, but watch for motorbikes, livestock, and unmarked speed bumps. Avoid night driving as road lighting is scarce outside cities. Emergency contact: Cambodian police 117, ambulance 119.

Family: Restaurants and restrooms are plentiful near Phnom Penh and a few towns; child seats are not standard in rentals, so bring your own. Pets: many hotels in Cambodia accept pets, but always confirm in advance; keep your pet's vaccination records handy for border inspection.

• Best rest stops: Riverside café in Neak Loeung (km 60 after border), the Phnom Penh bypass area has many fuel stations with mini-marts.
• Fatigue management: plan for 2–3 breaks; take a longer rest at Phnom Penh (roughly midway) – the Olympic Market area has parking and air-conditioned cafés.
• Hidden spot: Phnom Udong, ancient capital, is 40 km north of Phnom Penh – a short detour for hilltop temples and panoramic views.

Scenery: delta rice paddies and orchards give way to flooded grasslands and the Tonlé Sap floodplains near Kampong Chhnang, a region known for its floating villages and pottery. The route parallels the Mekong River for long stretches, offering views of ferries and river traffic.

Local commerce: Sa Dec is famous for flower villages; Kampong Chhnang is a hub for traditional Khmer pottery – stop at the pottery villages south of town. Along the way, roadside stalls sell tropical fruits, and you'll encounter local markets that give authentic glimpses of everyday life.

Border crossings: the Vĩnh Hường (Vietnam) – Kaam Samnor (Cambodia) crossing is open daily 07:00–22:00 (Vietnam time) and 06:00–21:00 (Cambodia time). You'll need a valid passport, Cambodian visa (available on arrival for most nationalities, $30), and vehicle import paperwork – check current requirements before you travel.

• Road quality: Vietnamese side – paved, well-maintained; Cambodian side – mostly good asphalt, but some sections near Kampong Chhnang are narrow with potholes.
• Fuel costs: gasoline ~$1.10/liter in Vietnam, ~$1.15/liter in Cambodia; estimate 35–40 liters total (~$40–45).
• Currency: Vietnamese dong and US dollars accepted near border; Cambodian riel and US dollars elsewhere – cash is king for tolls and small vendors.
