Sa Kaeo to Long Xuyen: Road Trip Guide & Hidden Gems

Sa Kaeo, a Thai province bordering Cambodia, and Long Xuyen, the capital of An Giang in Vietnam's Mekong Delta, are linked by a route that crosses two international borders. A historical note: this corridor follows part of the old Route Coloniale 1, built by the French in the early 20th century to connect Saigon with Phnom Penh. Today, the drive covers roughly 450 kilometers, with the Thai-Cambodian border at Aranyaprathet and the Cambodian-Vietnamese border at Tinh Bien.

This table summarizes key travel facts:

Before you go, check visa requirements for Cambodia and Vietnam—many nationalities can get e-visas or visa-on-arrival at the borders.

From Sa Kaeo city, take Thai Highway 33 to Aranyaprathet, cross into Poipet, Cambodia. Then follow National Road 5 through Sisophon to Phnom Penh. From Phnom Penh, head west on National Road 1 to the Vietnam border at Tinh Bien. Once in Vietnam, continue on QL91 to Long Xuyen.

Essential route details:

• Road quality: Good on Thai side, fair on Cambodian NR5, good on Vietnamese QL91.
• Tolls: No tolls on Thai and Cambodian sections; minor tolls on Vietnamese expressways (if used).
• Fuel: Fuel stations available every 50–100 km in all three countries; carry cash for smaller stations.
• Currency: Thai Baht, Cambodian Riel (USD accepted), Vietnamese Dong.

The border crossings can be congested; plan for 1–2 hours at each.

Road conditions vary: potholes on Cambodian roads, narrow bridges in Vietnam, and heavy traffic in Phnom Penh. Drive defensively, use daytime headlights, and avoid night driving in rural areas. Emergency numbers: Cambodia 117 (police), Vietnam 113 (police).

Family and pet-friendly stops:

• Sisophon: A hotel with a swimming pool (e.g., Grand Phnom Penh Hotel) is a good break.
• Phnom Penh: Riverside park is open and safe for kids.
• Chau Doc (Vietnam): Hoa Hao and Tay An Pagoda are serene places to stretch legs.

For fatigue management, plan essential stops every 2–3 hours. Notable rest zones: Aranyaprathet (Thai border), Sisophon, Phnom Penh, and Chau Doc. If you need tips on discovering such stops, see how to find the best stops and hidden gems between cities.

Hidden off-route spots: Banteay Chhmar (Cambodia) is a remote Angkor-era temple complex, about 140 km north of Sisophon. Ungrateful for time? Consider a detour to the Sam Mountain area near Tinh Bien for sunset views.

The route traverses three distinct landscapes: the dry plains of Sa Kaeo, the Tonlé Sap floodplains in Cambodia, and the lush Mekong Delta. The Cambodian stretch offers views of rice paddies and palm trees, while Vietnam's delta is a maze of canals and waterways.

Natural attractions:

• Phnom Srok (Cambodia): a small hill with a pagoda, about 30 km off NR5.
• Tonlé Sap Lake (via a detour to Battambang): Southeast Asia's largest freshwater lake.
• Tra Su Cajuput Forest (Vietnam): a flooded forest reserve with birdwatching, about 30 km from Tinh Bien.

Local commerce: In Poipet, expect duty-free shops and casinos. In Long Xuyen, visit the floating fish farms on the Hau River. The route is dotted with markets selling tropical fruits—durian, mangosteen, and dragon fruit.
