Trat to Kampong Cham Road Trip Guide: Best Stops & Tips

The route from Trat to Kampong Cham covers roughly 250 kilometers, crossing the Thai-Cambodian border at Hat Lek and continuing on Cambodian National Road 7. This drive takes about 5 to 6 hours depending on border formalities and road conditions. It’s a journey that shifts from Thailand’s lush coastal plains to Cambodia’s central lowlands, with the Cardamom Mountains looming to the west.

Historically, this corridor was part of the ancient trade routes linking the Gulf of Siam to the Mekong basin. Today, it’s a practical drive for overland travelers, offering a mix of agriculture, rubber plantations, and emerging towns.

The drive begins in Trat province, famed for its fruit orchards and mangroves. As you head east, the landscape shifts to rubber and palm oil plantations on the Thai side. Crossing into Cambodia, you enter the Cardamom Mountains, a biodiversity hotspot where rainforest meets coastal wetlands. Keep an eye out for wildlife intersections.

Shortly after the border, consider a detour to the Tatai River and Waterfall (about 22 km from Cham Yeam), a popular spot for kayaking. Further along, the town of Koh Kong offers the Peam Krasop Wildlife Sanctuary and Koh Kong Island, but these are off-route. Near Kampong Cham, the Mekong River becomes the main feature, with scenic views from bamboo bridges and riverfront promenades.

• Best stops Trat to Kampong Cham: stop at the Cardamom Tented Camp near Tatai for a nature immersion.
• Local commerce: Markets in Koh Kong and Serei Saophoan sell dried fish, tapioca, and soy sauce; Kampong Cham is known for its cotton weaving.
• UNESCO World Heritage Sites: none directly on route, but a major detour to Angkor Wat is possible though not recommended for this drive due to time.

Crossing at Hat Lek (Thailand) and Cham Yeam (Cambodia) is the most direct route. Ensure your vehicle has proper insurance and carry original registration documents. The border is open daily from 7 AM to 8 PM Thai time (UTC+7) and 6 AM to 7 PM Cambodian time (UTC+7), observe the time difference.

Fuel stations are readily available in Trat and in Cambodian towns like Krong Koh Kong and Serei Saophoan, but it’s wise to fill up before crossing. Diesel and gasoline are cheaper in Cambodia, but quality can vary; stick to major stations like Sokimex or Caltex to avoid fuel contamination. Budget for tolls and border fees: about 200 Baht (US$6) for Thai exit, and Cambodia entry fee roughly US$30 for a car.

• Highway: Once in Cambodia, National Road 48 to Koh Kong, then NR 4, then NR 7 towards Kampong Cham.
• Road quality: Well-paved but narrow in parts; potholes are common after rainy season.
• Key milestones: Trat (km 0), Hat Lek (km 86), Koh Kong (km 100), Serei Saophoan (km 190), Kampong Cham (km 250).

Road conditions vary; Cambodian roads have improved but still have unexpected hazards like livestock and unlit carts at night. Avoid driving after dark due to poor visibility and unpredictable traffic. Use seatbelts, obey speed limits, and be cautious at intersections.

For families, there are several clean rest stops with playgrounds at large fuel stations, especially in Cambodia. The Kbal Chay River Snacks in Siem Reap is not on route, but similar venues exist around Serei Saophoan. In Kampong Cham, the riverfront park is a child-friendly area.

Fatigue management: Plan breaks every 2 hours. Good rest areas include the Kiry Sokha gas station near Serei Saophoan and the Amatak Hotel in Kampong Cham. They offer restaurants and clean washrooms.

• Pet-friendly framework: Many guesthouses allow pets, but some national parks require leashes; check in advance.
• Hidden off-route spots: Phnom Pros and Phnom Srei temples in Kampong Cham are worth a short drive; also visit the bamboo bridge (seasonal) across the Mekong.
• Fatigue management: Use the simple rule 'Ride, Rest, Rehydrate' - stop at roadside stands for fresh coconut or sugarcane juice.
