Introduction
The drive from Long Xuyen in Vietnam's Mekong Delta to Kampong Thom in central Cambodia crosses the border at Vinh Xuong/Kaam Samnor and covers roughly 320 kilometers. The first 40 kilometers follow National Route 91 through lush rice paddies, but the route shifts abruptly at the border to Cambodia's National Highway 1, a road that carries heavy truck traffic between Phnom Penh and Ho Chi Minh City.
This route is not a typical tourist corridor, but it offers a raw slice of Mekong life and a gateway to Cambodia's ancient temples.
| Segment | Distance | Estimated Time |
|---|---|---|
| Long Xuyen to Border | 40 km | 1 hour |
| Border to Phnom Penh | 150 km | 2.5 hours |
| Phnom Penh to Kampong Thom | 130 km | 2.5 hours |
Route Logistics and Infrastructure
Border crossing at Vinh Xuong (Vietnam) and Kaam Samnor (Cambodia) is straightforward, but visa on arrival is available only at certain checkpoints; check current rules. After crossing, the road improves on Cambodia's NR1, but fuel stations become sparse outside Phnom Penh; fill up before leaving the city.
- Fuel costs: Vietnamese petrol ~24,000 VND/liter; Cambodian fuel ~4,000 KHR/liter (about $1), but prices vary along route.
- Tolls: Vietnam has a few small tolls on NR91; Cambodia's NR1 is toll-free. Bridge crossings near Phnom Penh may have small fees.
- Road quality: NR91 is narrow but paved; NR1 is mostly smooth, with rough patches near construction zones.
- Driving time: total 5-6 hours without stops; plan for 7-8 hours with border procedures and breaks.
Road Safety, Family Stops, and Fatigue Management
Traffic in Cambodia is chaotic; watch for motorbikes and livestock crossing the road. Wear seatbelts, and avoid night driving due to poor lighting on NR1. For families, the journey is doable with children, but ensure frequent bathroom breaks – clean restrooms are rare, especially between Phnom Penh and Kampong Thom.
For pet owners, no specific restrictions on the route, but keep your dog on a leash at stops and carry water. Many Cambodian restaurants are open-air and may allow pets, but always ask.
- Rest zones: Phnom Penh (after border) and Kampong Thom city are good spots for long breaks.
- Fatigue management: split the drive with an overnight in Phnom Penh if crossing early in the day.
- Hidden off-route spots: the 11th-century temple of Prasat Kok Rokar, 10 km west of Kampong Thom, is seldom visited and offers a peaceful picnic spot.

Natural Landscapes and Local Commerce
The flat delta gives way to Cambodia's central plains, with occasional sugar palm trees and lotus ponds. Near Phnom Penh, the landscape is dotted with typical Khmer stilt houses and bustling markets.
Just off the route, 20 km north of Kampong Thom, lies the pre-Angkorian temple complex of Sambor Prei Kuk, a UNESCO World Heritage Site since 2017. Its brick sanctuaries predate Angkor Wat by centuries.
For roadside commerce, Vietnamese side offers tropical fruits like mangosteen and rambutan; Cambodian side has grilled meat skewers and fried insects in small towns. The town of Skun, about 70 km north of Phnom Penh, is famous for its deep-fried spiders – a daring snack for adventurous eaters.
The best stops from Long Xuyen to Kampong Thom include the floating village of Chong Kneas on the Tonle Sap lake, but this requires a detour of 30 km from Kampong Thom. If time permits, it's worth driving Long Xuyen to Kampong Thom solely to experience the contrast between Vietnamese delta life and Cambodian rural traditions.
