Long Xuyen to Kampong Chhnang: Road Trip Guide

The drive from Long Xuyen, Vietnam, to Kampong Chhnang, Cambodia, covers about 380 kilometers on a route that crosses the Mekong Delta's flat expanse, the border at Vinh Xuong, and the Cambodian countryside near the Tonle Sap. This guide focuses on practical details that make the trip manageable, from road quality to family-friendly stops.

The route hugs flatlands, with rice paddies stretching endlessly on the Vietnamese side. As you cross into Cambodia, the landscape shifts to drier fields and scattered sugar palm trees, a hallmark of Kampong Chhnang province. The town itself, known for its ancient pottery kilns (Wat Phsar), offers a glimpse into traditional Khmer craftsmanship.

For cultural immersion, stop at Phnom Penh's Central Market (Phsar Thmei) for local textiles and fresh produce. Hidden off-route spots include the Koh Oknha Tei island in the Mekong, reachable by ferry from Phnom Penh, where you can see silk weaving villages and fine the how to find the best stops and hidden gems between cities.

Road conditions on the Vietnamese side are generally good, with well-marked lanes and adequate lighting near towns. In Cambodia, National Road 1 is wide but has potholes, especially after heavy rain; National Road 5 is undergoing upgrades but is still narrow in stretches. Always keep headlights on, as many locals drive with them off.

Rest zones are plentiful in Vietnam (every 50 km, with clean toilets), but in Cambodia they are rare—your best bet is the junction town of Prek Kdam, where a few simple cafes offer shaded tables. If traveling with children, carry snacks and entertainment; the long straights won't distract them. For pets, keep a leash and water bowl; many eateries allow pets on outdoor patios, but not inside.

To manage fatigue, plan to stop every two hours, alternating drivers if possible. The journey from Phnom Penh to Kampong Chhnang is a gentle two-lane road with little traffic, making it a relaxed end to the trip. Avoid driving after dark on rural sections in Cambodia, where livestock and unlit carts pose a hazard.

You'll spend most of the journey on Vietnamese National Route 91 to the border, then switch to Cambodian National Road 1 toward Phnom Penh, and finally National Route 5 north to Kampong Chhnang. The border crossing at Vinh Xuong (Vietnam) and Kaam Samnor (Cambodia) is less trafficked than others, but it closes from 20:00 to 06:00, so plan to cross during daylight.

• Fuel stations are frequent on the Vietnamese side (every 30–50 km) but sparse in Cambodia after Phnom Penh; fill up before leaving the capital.
• Diesel costs around 24,000 VND per liter (about $1) in Vietnam and 3,900 riel (about $0.95) in Cambodia; gasoline is similar.
• Tolls: Vietnamese highways cost about 230,000 VND ($10) for a car; Cambodian roads have no tolls.
