Siem Reap to Ben Tre: Ultimate Vietnam Road Trip Guide

Beginning in Siem Reap, home to the Angkor Archaeological Park, the road to Ben Tre winds through Cambodia and Vietnam, ending in the Mekong Delta. The journey spans roughly 700 kilometers, crossing two international borders and multiple ecological zones.

Before departing, note that your vehicle must have a Carnet de Passage for Cambodia and a temporary import permit for Vietnam, obtainable at the border. The drive typically takes 12-14 hours of pure driving time, but plan for at least two days to fully experience the route.

Both countries drive on the right; seatbelts are mandatory. In Cambodia, watch for motorbikes and livestock; in Vietnam, expect heavy traffic in Ho Chi Minh City. Use headlights at all times, and be cautious of unlit vehicles at night.

For families, the route offers kid-friendly stops like the Phnom Penh Zoo and the Saigon Zoo and Botanical Gardens. Rest areas are available at gas stations and roadside parks, but plan breaks every 2-3 hours to combat fatigue.

Pet-friendly accommodations are increasing, but always call ahead to confirm pet policies. The route lacks dedicated pet rest stops, so bring water and waste bags for walks.

Hidden off-route gems include the Tam Coc rice fields (if you extend north) or the coconut candy workshops in Ben Tre itself. For more tips on discovering such spots, see this how to find the best stops and hidden gems between cities.

Is it worth driving Siem Reap to Ben Tre? Absolutely, for the flexibility and the immersive experience. How long to drive Siem Reap to Ben Tre? Expect 12-14 hours of driving over two days. The best stops Siem Reap to Ben Tre include Phnom Penh, My Tho, and the Cu Chi Tunnels. For things to do between Siem Reap and Ben Tre, consider a cooking class in Ho Chi Minh City or a boat tour in the delta.

Leaving Siem Reap, the landscape transitions from arid plains to the lush Mekong Delta. In Cambodia, you'll pass through rice paddies and palm groves, while Vietnam's delta offers intricate canal networks and coconut plantations.

The climate is tropical monsoon: dry season (November to April) brings cooler temperatures and clear skies, ideal for driving; wet season (May to October) sees heavy downpours, but the countryside turns vividly green.

Along the way, stop at local markets like Phnom Penh's Central Market for souvenirs, or in My Tho to sample fresh tropical fruits. Culinary infrastructure is abundant: roadside stalls serve noodle soups, banh mi, and grilled meats, with vegetarian options increasingly common.

UNESCO World Heritage Sites on the route include Angkor in Siem Reap and the ancient town of Hoi An, though Hoi An is a detour; the route itself passes near the Cu Chi Tunnels, a historical site, but they are not UNESCO-listed.

National Highway 6 (NR6) connects Siem Reap to Phnom Penh, a well-paved two-lane road. From Phnom Penh, take National Highway 1 (NR1) to the Moc Bai border crossing, then continue on Vietnam's QL22 to Ho Chi Minh City. Finally, use QL1A and provincial roads to reach Ben Tre.

• Fuel prices: Cambodia ~$1.15/liter, Vietnam ~$1.20/liter (as of 2025).
• Road tolls in Vietnam: ~$10 total for the entire route.
• Border crossing hours: Moc Bai (24/7), but expect 1-2 hours for paperwork.
• Visa requirements: Vietnam e-visa for most nationalities, apply online a month ahead.

The route crosses the Mekong River via ferry at My Thuan, a free service running 24/7. Road quality varies: NR6 and QL1A are smooth, but provincial roads near Ben Tre may have potholes, especially after rains.

For real-time traffic and road conditions, use local apps like Waze or Google Maps, but download offline maps as coverage can be spotty in rural areas.
