Vung Tau to Kampot: A Coastal Road Trip Guide

Vung Tau, Vietnam's southern beach resort, sits on a narrow peninsula known as the 'Pearl of the Orient' for its French colonial villas and offshore oil rigs. From this bustling port, National Route 51 and 1A lead you to the Cambodian border at Moc Bai, a route traversing the flat Mekong Delta floodplain before rising into Kep province's limestone hills.

This article answers whether this drive is worth it, what to see between Vung Tau and Kampot, and how long it takes. We're here to give you a practical, no-nonsense guide for a road trip that mixes highway cruising with coastal charm, all within a day's drive.

Leaving Vung Tau, you climb the Long Hai hills, a sudden green spine after the flat coastline. Here, pineapple plantations and pepper farms give way to the verdant rice paddies of the Mekong Delta, an endless mirror of water and sky. Crossing into Cambodia near Bavet, the landscape transforms into Cambodia's 'Swiss Alps' region, with the hazy blue Cardamom Mountains on the horizon. Look for the white-barked 'Kampot pepper' vines on wooden poles as you approach Kampot—the terroir of this region, with its schist and laterite soils, produces the prized Kampot peppercorns that fetch a premium worldwide.

In Kampot, the riverfront promenade hums with cafés and guesthouses, but the real local commerce centers on the shrimp farms and salt fields along the coast road. The town's night market serves fresh crab and steamed buns, a blend of Vietnamese and Khmer flavors

UNESCO Sites and Hidden Gems

• Sanctuary of Preah Vihear, a Khmer temple perched on a 525-meter cliff in the Dângrêk Mountains, is a 5-hour detour from Kampot—far for a day trip but a bucket-list stop for temple enthusiasts.
• An off-route gem: the salt fields and bird-watching towers at the Teuk Chhou River estuary near Kampot's coast. Take a boat trip at dawn to spot hornbills and kingfishers when the water is calm.
• The Bokor Hill Station, an abandoned French hill resort 21 km from Kampot, offers ghost-town ruins and a cool climate at 1,000 meters above sea level—worth the winding mountain route for the waterfall at Popokvil.

Vietnam's QL1A is mostly divided highway with speed limits up to 90 km/h, but it cuts through numerous towns with heavy motorbike traffic, so vigilance is key. Cambodia's NH2 is narrower, with two lanes and frequent overflows of trucks and farm vehicles. Both countries have a high incidence of accidents involving cars and motorbikes, so defensive driving and turning on headlights even in daylight are advisable (in Cambodia, headlights are legally required at all times).

For families, the trip is manageable with rest stops every two hours. In Vietnam, the Ben Luc Petroservice (actually near Long An) has a clean WC and a playground, while in Cambodia, the Prasot rural market provides a shaded picnic spot with fresh fruit and hammocks.

Pet-Friendly Framework, Fatigued Driving, and Local Culture

• Pets can cross the border with an international health certificate and rabies vaccination record; both countries require quarantine if the pet looks ill.
• Most Cambodian guesthouses are pet-friendly, but Vietnamese hotels in Vung Tau may charge a cleaning fee.
• To avoid sleepy driving, plan to stop at the Dalat intersection coffee shop (Vietnamese) and the Kompong Trach market (Cambodian), where you can stretch legs and grab a caffeine hit.
• Local culture tip: when passing a pagoda, slow down and keep your horn silent to respect temple grounds; honking in Cambodia is considered rude near religious sites.

The most direct path takes you from Vung Tau north on QL51 to Long Thanh, then west onto QL1A through Bien Hoa and toward the border. After clearing immigration, Cambodia's NH1 runs flat to Phnom Penh, but a faster, less congested inland route via NH2 to Kampot saves time and offers better scenery. Watch for potholes and unmetered speed bumps on Cambodia's secondary roads; they're common and can damage low-slung cars if you're not paying attention.

Fuel costs: as of early 2025, petrol runs about 25,000 VND (≈1 USD) per liter in Vietnam and around 4,200 KHR (≈1.05 USD) in Cambodia. Fuel stations in Vietnam are plentiful on QL1A; in Cambodia, they're sparse once you leave National Highway 2, so plan to fill up at Bavet or Neak Loeung before heading south.

Costs, Border Formalities, and Documents

• Vehicle papers: You'll need the vehicle's registration, a valid international driving permit (IDP) for Vietnam and Cambodia, and a temporary import permit (carnet de passage) if you're crossing in a non-ASEAN plated car. Truck and bus drivers must pay a road tax at the border.
• Border hours: Moc Bai–Bavet is open 24/7, but expect delays of 1–2 hours during peak daytime hours; at night it's faster.
• Tolls: Vietnam's QL1A has several toll booths; total tolls from Vung Tau to the border amount to roughly 100,000 VND (≈4 USD). Cambodia's NH2 is toll-free, but there are occasional informal checkpoints.
• If you're short on time, consider leaving Vung Tau by 5 a.m. to beat Saigon's morning congestion around Bien Hoa.
