Nakhon Nayok to Kampong Cham: Road Trip Guide

The drive from Nakhon Nayok to Kampong Cham, roughly 430 km, crosses the disputed Preah Vihear temple area—a border region that has seen military clashes, so check the latest travel advisories before setting out. The route begins in Thailand's lush central plains and ends at the Mekong River in Cambodia, a journey that spans two distinct cultural landscapes.

Driving time is typically 7–8 hours without stops, but you'll want to factor in border crossing formalities at Aranyaprathet–Poipet. For a smoother trip, plan to cross early morning to avoid queues.

In Thailand, the route passes through sugarcane and cassava fields, with distant views of the Dongrak Mountains. After Poipet, the landscape flattens into rice paddies and palm trees—a classic Cambodian scene. Along National Road 6, you'll notice rural markets selling local fruits and handicrafts; stop at one for a taste of dried banana or palm sugar.

While no UNESCO World Heritage Sites lie directly on this route, the Preah Vihear temple—a World Heritage Site—is a considerable detour (about 100 km from Sisophon) and worth the extra drive if time permits.

Road safety is generally okay, but watch for livestock on Cambodian roads and occasional potholes. For families, an entertaining pitstop is the 'Ta Kream' crocodile farm near Battambang, though it's a short detour. For a quick stretch, rest areas along Thai Route 33 have clean toilets and food courts.

To manage fatigue, plan to stop every two hours. A convenient midpoint is Sisophon, with several air-conditioned cafes. For pet owners, some rest stops with green areas allow leashed pets—look for the 'dog' signs.

Hidden gems: Just before Poipet, Hua Laem market offers local Thai sweets; in Cambodia, the town of Skuon is famed for its fried tarantulas—a local delicacy that adventurous eaters might try. For more tips on finding such spots, see how to find the best stops and hidden gems between cities.

From Nakhon Nayok, take Route 33 east toward Aranyaprathet. The road is well-paved with moderate traffic; petrol stations and rest stops appear every 20–30 km. In Cambodia, from Poipet, National Road 5 leads to Sisophon, then National Road 6 continues to Kampong Cham. Expect road quality to be slightly rougher, but acceptable for sedans.

Fuel costs are lower in Cambodia, but you'll pay in US dollars or riel. Budget around 1,500 baht for tolls and fuel in Thailand, plus Cambodia tolls and fuel for about $35–45.

• Border crossing: Aranyaprathet–Poipet open 6:00–22:00; have passport and vehicle papers ready.
• Car insurance: Thailand's coverage doesn't extend across the border; buy Cambodian insurance at the border.
• Local currency: Cambodian riel (US dollars widely accepted).
