Chon Buri to Svay Rieng: Road Trip Guide

The Bangkok–Chon Buri–Svay Rieng corridor is a vital trade artery, carrying much of Thailand's east–west traffic into Cambodia. The route crosses the border at Ban Laem–Daun Lem (Koh Kong) or Aranyaprathet–Poipet, with the latter being far more common for passenger vehicles. Estimated driving time is 6–7 hours for the 350 km journey, depending on border crossing and traffic.

This guide covers fuel stops, natural highlights, family and pet needs, and hidden corners, so you can plan a smooth trip.

Just north of Chon Buri, the Khao Kheow Open Zoo (about 30 minutes detour) offers a family-friendly wildlife encounter. As you head east, the land flattens, and rice paddies dominate the view near Sa Kaeo. At the border, the Poipet market is a chaotic hub of duty-free goods and local crafts.

Hidden off-route: the Prasat Ta Muen Thom ruins (near Surin, about 90 min north of Aranyaprathet) are a classic Khmer temple, but not a UNESCO site. For a UNESCO-listed site, you'd need to detour to Phanom Rung (about 2.5 hours north), which is not on this route.

From Chon Buri, take Route 344 to Route 33, then follow Route 33 to Aranyaprathet. After crossing into Cambodia, continue on National Road 5 to Poipet, then south on National Road 1 to Svay Rieng. Road quality is good on the Thai side (paved, well-marked), while Cambodian sections are narrower with some potholes.

• Fuel: Gas stations frequent every 30–50 km on Thai side; fewer and pricier in Cambodia. Fill up at Aranyaprathet before departure.
• Tolls: No direct tolls on Expressway 7 (Bangkok–Chon Buri) if you detour early, but Route 33 has no tolls.
• Border crossing: Aranyaprathet–Poipet is busiest; open 6am–10pm. Prepare passport, vehicle registration, and insurance.

Road safety is generally good on Thai highways, but watch for slow farm vehicles near villages. In Cambodia, drive defensively; overtaking requires care. Rest areas are scarce after Aranyaprathet, so plan breaks at fuel stations with restaurants.

• Family stops: Khao Kheow Open Zoo (above), plus the Sa Kaeo Crocodile Farm for a quick look.
• Pet-friendly: Many Thai roadside restaurants allow pets on outdoor terraces, but inside the border crossing, pets must have a health certificate.
• Rest zones: At the border, there are formal rest areas with food and WC; use them to reduce fatigue.
