Poipet to Svay Rieng: Drive Time, Best Stops & Hidden Gems

Stretching nearly 400 km from the Thai border at Poipet to the Vietnamese frontier town of Svay Rieng, this route follows National Road 5 east to Phnom Penh, then National Road 1 southeast. The drive typically takes 5 to 6 hours without traffic, but expect longer during peak hours in Phnom Penh.

Along the way, you'll traverse the flat, agricultural heartland of Cambodia, crossing the Tonlé Sap river at Prek Kdam and skirting the Mekong before reaching Svay Rieng.

Note that the above times are approximate and assume good road conditions. The total drive can be comfortably done in a day, but many choose to break it up.

National Road 5 is well-paved for most of its length, though sections near Battambang and Pursat may have potholes after rains. National Road 1 to Svay Rieng is excellent, recently upgraded.

Fuel stations are plentiful along NR5 and NR1, but fewer on the secondary roads. Plan to refuel in Poipet, Battambang, and Phnom Penh. Diesel costs about 4,500 riel/liter ($1.10); gasoline slightly more.

• Border crossing at Poipet is busy; allow 30-60 minutes for passport control.
• Svay Rieng's Bavet crossing to Vietnam is less congested.
• Tolls on NR1 from Phnom Penh to Neak Loeung: 5,000 riel for cars.
• Remember to purchase Cambodian vehicle insurance at the border.

The landscape is predominantly rice paddies, with palm trees and occasional villages on stilts. As you approach Battambang, the Cardamom Mountains appear to the west, a lush, forested range home to waterfalls and wildlife.

Near Battambang, the Phnom Sampeau caves and the bamboo train are not UNESCO-listed but offer cultural insight. A two-hour detour to the temple complex of Angkor Wat is possible, but it's not on this route.

Local markets in Sisophon and Battambang sell fresh tropical fruits, particularly durian and mangoes. In Svay Rieng, the border trade with Vietnam drives a bustling commerce, with many shops selling imported goods.

For a taste of Cambodian street food, try num banh chok (Khmer noodles) at numerous roadside stalls, especially in Battambang.

The roads are generally safe, but be cautious of overtaking buses and trucks, especially at night. Speed limits are 90 km/h on highways and 40 km/h in towns. Checkpoints are common, so keep your documents ready.

For families and pets, Plan your breaks at the rest areas near Serei Saophoan and Krek, which have basic amenities and green spaces. The journey is child-friendly if you pack snacks and a first-aid kit, but remember that few restaurants have high chairs.

To avoid fatigue, take a break every two hours. Several large petrol stations along NR5 have cafes and toilets. Phnom Penh is the ideal halfway stop with a wide range of hotels and restaurants.

Hidden gems off the main road include the Battambang Bat Caves, which are spectacular at dusk, and the sleepy town of Kompong Chhnang, known for its pottery villages.
