Kampot to Long Xuyen Drive: Top Stops, Times, Safety

The border crossing at Prek Chak (Kampot) to Xa Xia (Long Xuyen) is one of the few places where Cambodia's National Road 33 meets Vietnam's National Highway 91, two ribbons of asphalt that have carried merchants between the Gulf of Thailand and the Mekong Delta since the 19th century. Buses usually require a 4-hour journey, but driving yourself opens up a world of detours. Below is a dense, practical guide to the route, from the secret waterfalls of the Elephant Mountains to the floating markets just past Long Xuyen.

Road quality is mixed: the Cambodian stretch is mostly two-lane asphalt with occasional potholes, especially the 15-km section from Kampot to Kep. Vietnam's Highway 80 is in good condition but narrow in towns; watch for motorbikes running red lights. Use the how to find the best stops and hidden gems between cities guide to scout rest stops.

Rest areas are sparse in Cambodia; plan a coffee stop at the Durian Roundabout in Kampot before departure. Once in Vietnam, there are convenient service stations with clean toilets every 50 km on Highway 80. For families, the Teuk Chhou Rapids (5 km from Kampot) has shallow pools, but the area lacks child seats; consider bringing your own, as rental car companies rarely offer them. Pet-friendly policies are improving: the border permits pets with a health certificate and one-time inspection, but some Vietnamese hotels (like the Mekong Home in Long Xuyen) allow dogs.

To combat fatigue, schedule a break at Ha Tien (mid-point) to walk along the waterfront promenade. The only other town with significant services is Chau Doc, 30 km before Long Xuyen, but a detour to the Sam Mountain at sunset adds 40 minutes—worth it if you're not pressed. The route has a surprising number of hidden off-route spots: the Phu My Hiep Ancient House near Cao Lanh, 15 km north of Long Xuyen, is a 1900s wooden mansion with ornate carvings, often overlooked by tourists.

The route skirts the foothills of the Elephant Mountains, where the Teuk Chhou River carved a canyon near Kampot—a lesser-known spot for swimming and kayaking among limestone karsts. Just 10 km west of Kep, the salt fields and pepper farms give way to the coastal mangroves that feed Cambodia's famous crab market; don't miss the crab congee at the Kep crab market.

Beyond the border, the flat Mekong Delta landscape is a sea of emerald rice paddies, punctuated by the brown waters of the Bassac River. The Tra Su Cajuput Forest, 20 km south of Long Xuyen, is a flooded forest with a 5-km boat loop, home to storks and cajuput trees. In Long Xuyen itself, the floating market on the Hau River offers a taste of local commerce—vendors tie their boats to the bridge pilings every morning from 4 to 8 AM.

The optimal route follows National Road 33 from Kampot to the Prek Chak border, then Vietnam's Highway 80 and 91 via Ha Tien and Chau Doc. You'll cross the border at Prek Chak/Xa Xia, open daily from 6 AM to 10 PM. Ensure your vehicle has a Carnet de Passages if you're not driving a Cambodian-registered car—needed for temporary import into Vietnam.

Fuel economy is a key planning factor: Cambodia has cheaper petrol (around $1.10/liter) compared to Vietnam ($1.20/liter), so fill up before crossing. Along the Cambodian stretch, expect two fuel stations in Kep and one just before the border. Once in Vietnam, stations are frequent every 30 km on Highway 80.
