Suphan Buri to Kampong Cham: Road Trip Guide

The route from Suphan Buri to Kampong Cham begins at the Ang Thong junction on Route 3195, a road that once carried timber convoys to the Chao Phraya River. You'll cross the Thai-Cambodian border at Aranyaprathet/Poipet, then continue on Cambodia's National Road 5 and 6. This guide covers how long to drive Suphan Buri to Kampong Cham, what to expect, and the best stops along the way.

The total driving distance is approximately 340 kilometers, typically taking 6-7 hours including border formalities. This is a drive best undertaken with a full day of daylight, allowing for breaks and unexpected delays at the border. The route mixes Thai farmland with Cambodian countryside, giving a true sense of the region.

For driving from Suphan Buri to Kampong Cham, you'll take Route 33 through Sa Kaeo province to the border at Aranyaprathet. After clearing immigration and customs, continue on Cambodia's National Road 5 to Sisophon, then National Road 6 to Kampong Cham. The Thai side is well-paved and signposted; the Cambodian side is mainly two-lane asphalt with occasional potholes, especially between Sisophon and Kampong Cham.

Fuel and Costs

Fuel prices are higher in Cambodia than in Thailand, so fill up before crossing the border. Thai baht is widely accepted in Poipet, but use US dollars or Cambodian riel once inland. Tolls are minimal, only on the Thai side. Budget for border fees (approximately 1,500 baht for a private vehicle) and possible unofficial payments, which are discouraged.

• Thai fuel: ~30 baht/liter for gasoline
• Cambodian fuel: ~4,100 riel/liter (~1.02 USD)
• Border fee for car: 1,500 baht
• International driver's permit recommended

Road safety on this route requires vigilance, especially in Thailand where traffic is left-hand, and in Cambodia where many vehicles are older and roads are shared with motorbikes and livestock. On the Cambodian side, watch for unmarked speed bumps and occasional flooding. For family travel, the route offers kid-friendly stops like the Khao Khitchakut National Park (near Chanthaburi) and the Phra Siam Devathiraj Shrine in Aranyaprathet. For pets, careful with border regulations: you'll need a pet passport and possibly a quarantine inspection.

To manage fatigue, plan rest stops every 1.5-2 hours. In Thailand, the rest area at Wang Sombun (around km 70 from Suphan Buri) is a popular spot. In Cambodia, consider stopping at Sisophon or Serey Sophoan for a meal. For a more scenic break, the Banteay Chhmar temple complex, though off the main route, is a hidden gem worth the detour.

Family and Pet-friendly Notes

• Khao Khitchakut offers waterfalls and a shrine for a nature walk.
• Pet requirements: microchip, rabies vaccination certificate, and import permit from Cambodia's Animal Health and Production Office.
• Restrooms are basic; carry your own toilet paper and hand sanitizer.

The landscape shifts from the flat, rice-growing plains of Suphan Buri to the scrubby forests of Sa Kaeo, then to the fishing villages along the Tonle Sap basin in Cambodia. As you approach Kampong Cham, the Mekong River becomes visible, and you'll notice tobacco and rubber plantations dotting the red-earth hills. The climate is tropical with a distinct rainy season from May to October; during the dry months of November to February, the drive is more pleasant and the scenery greener.

Local commerce thrives along the route, with roadside stalls selling fresh fruit—especially durian near Chanthaburi if you take a slight detour, and palm sugar in Cambodia. In towns like Sa Kaew and Poipet, markets offer everything from motorcycle parts to Buddhist amulets. The Cambodian town of Kampong Cham is famous for its bamboo river bridge and the French-era buildings in its old quarter.
