Chaiyaphum to Prey Veng Road Trip: Essential Guide

Leaving Chaiyaphum at the Phu Laen Kha viewpoint, the Thanon Mittraphap (Highway 2) stretches southeast, but most drivers immediately turn onto Route 201, cutting through the Sankamphaeng Range's southern ridge. This 680-kilometer journey merges two distinct road cultures: Thailand's left-hand driving and Cambodia's chaotic yet organized flow.

The route crosses the Mekong River at Nong Khai, but the fastest border is at Chong Sa Ngam (Ubon Ratchathani) for Prey Veng, adding 60 kilometers but saving border processing time. Expect 11-12 hours of drive time, not counting stops.

The Thai section is well-lit but some curves lack guardrails, so drive defensively. In Cambodia, watch for livestock crossings and unlit vehicles at night. Family-friendly breaks include the dinosaur-themed park in Surin (Thailand) and the palm-shaded picnic area at Snuol (Cambodia).

For pets, Thai rest stops often have shaded spaces, but Cambodian stops are less pet-focused. Major rest areas every 100 km have basic facilities; plan for 20-minute power naps every 3 hours. Petrol stations double as mini-marts, but food variety is better in Thailand.

Between Chaiyaphum and Ubon, the Pha Taem cliff views over the Mekong reward a short detour. After crossing into Cambodia, the landscape flattens into rice paddies and sugar palm groves, especially near the Tonle Sap basin.

Local markets like Ban Phrao (silk weaving) and Kampong Ro (fish cracker production) offer authentic souvenirs. The Prey Veng market sells famous palm sugar and fresh Mekong river fish.

The Thai side boasts well-marked highways with regular toll booths only near cities, but Cambodia's National Road 13 is two lanes with occasional potholes. Fuel prices average 25 baht/liter in Thailand and $1.20/liter in Cambodia, so fill up before the border.

• Thai fuel stations with clean restrooms every 50 km on Route 201.
• Cambodian stations accept US dollars and riel, but credit cards work only at major towns like Serei Saophoan.
• Border crossing docs: Passport with 6-month validity, vehicle registration, and insurance (Green Card for Thailand, compulsory Cambodian third-party at border).
