Ha Tien to Stung Treng: Border Secrets & Route Guide

Leaving Vietnam's southern coast at Ha Tien, the route to Stung Treng in Cambodia crosses the Xa Xia border gate and follows the winding roads of Kampot, Kep, and the Mekong's eastern plains. This 340-kilometer journey takes roughly seven hours in good conditions, along a mix of national roads and provincial highways.

Ha Tien is known for its limestone karst scenery and the nearby Thach Dong cave pagoda, a historical site from the 18th century. After crossing the border, the first major town is Kampot, famous for its pepper farms and riverside charm, though you'll bypass the town center on NH3.

The scenery shifts from Vietnamese coastal plains to Cambodian lowlands, with the Elephant Mountains visible to the south. Between Kampot and Phnom Penh, you'll cross the Tonle Sap floodplain, where rice paddies stretch to the horizon. The final segment into Stung Treng follows the Mekong's eastern bank, passing through remote forests and ethnic minority villages.

UNESCO World Heritage Sites are not directly on the route, but the Temple of Preah Vihear lies about 150 km north of Stung Treng, a possible detour for those willing to add four hours. The route's main attractions are nature-based: Bokor National Park near Kampot offers hiking and waterfalls, and the Irrawaddy dolphins at Kampi near Kratie are a must-see, just 30 km south of Stung Treng.

Local commerce thrives in the roadside markets, where you can buy fresh tropical fruits, Kampot pepper, and woven crafts. In the village of Chhbar Morn, a morning market (6–9 AM) sells handwoven krama scarves and traditional snacks like num banh chok (Khmer noodles). Gas stations offer modest eateries with noodle soups and coffee for under $2.

As you approach Stung Treng, the density of stalls and small eateries increases, with stalls selling river fish and dried fish. The town itself is a trading hub, where you can find local handicrafts and a vibrant riverside market.

Traveling with children and pets requires planing, as roadside infrastructure is limited. The route has no dedicated rest areas, but you'll find ample opportunities at gas stations and temple grounds, which often have shade and clean restrooms. For kids, the beaches at Kep (20 km detour) offer a safe paddling spot, and the Kampot night market is family-friendly with food stalls and a playground area.

• Pet-friendly: Many small guesthouses and homestays near the border allow pets, but ask in advance. Restaurants tend to have outdoor seating where pets are tolerated.
• Road safety: Road lighting is absent between towns; avoid night driving from Skuon to Stung Treng because of occasional wildlife and slow-moving tractors.
• Fatigue: Take breaks every 2–3 hours; the stretch between Kampot and Phnom Penh is monotonous, so plan a stop at the Skun roundabout, famous for fried spider stalls.

Hidden off-route spots include the Phnom Sorsia viewpoint, 25 km before Kampot, offering panoramic views of the salt fields and the Gulf of Thailand. A lesser-known waterfall, Teuk Chhou, lies 10 km south of Kampot and is a local picnic spot with a natural pool.

For rest, the Kratie province has a riverside park where travelers often nap in hammocks shaded by tamarind trees. In Stung Treng, the riverfront promenade is a calm place to unwind, with many guesthouses offering dorms or private rooms at $10–25 per night.

Both countries drive on the right side, but Vietnamese vehicles are not allowed into Cambodia; you'll need to cross on foot and rent a local car or bus. At Xa Xia, passport control is efficient, with e-visas accepted since 2023. Currency exchange shops near the border offer acceptable rates, but ATMs are scarce after Kampot.

• Road numbers: Vietnam's QL80 ends at the border; Cambodia's National Road 2 (NH2) becomes NH3 to Kampot, then NH3 continues to Phnom Penh, but for Stung Treng, you'll turn off onto NH6 at Skun and then NH7.
• Fuel: Petrol stations appear every 50–70 km on main roads; prices are comparable to Vietnam, but quality can vary—stick to major brands like Sokimex or Total.
• Tolls: Cambodia has no tolls on these routes, but you'll pay small fees at a few informal checkpoints, each around 5,000 riel (about $1.25).

Tolls aside, driving costs are minimal: a full tank in Ha Tien costs about 1,200,000 VND (approx. $50) for a standard sedan, which will get you to Stung Treng with a third to spare. The route's overall condition is good, with smooth asphalt on NH2 and NH3, but the final stretch on NH7 between Skuon and Stung Treng is narrower and has some potholes.

For international drivers, an International Driving Permit is recommended; Cambodian police rarely stop foreigners but may ask for documents at checkpoints. Average driving speed is around 60 km/h due to towns and livestock crossings.
