Chon Buri to Kampong Thom: Ultimate Road Trip Guide 2024

The overland route from Chon Buri, Thailand to Kampong Thom, Cambodia spans approximately 400 kilometers, crossing the border at Aranyaprathet/Poipet. This drive typically takes 6-8 hours depending on border crossing time and traffic, making it a feasible weekend getaway or extended stopover for travelers heading to Siem Reap.

Historically, this corridor was part of the ancient Khmer Empire's trade routes, connecting the Gulf of Thailand to the Tonlé Sap basin. Today, it offers a blend of modern highways and rural landscapes.

As you leave Chon Buri, the coastal flatlands give way to cassava and sugarcane fields. Near the border, the landscape transitions to sparse forests and eventually into the Cambodian plains, with the distant Dângrêk Mountains looming north.

Local markets appear at frequent intervals; try fresh tropical fruits like rambutan and mangosteen at roadside stalls. In Poipet, the bustling market town offers a glimpse into cross-border commerce.

Along the way, small temples and shrines dot the countryside. Note that the famous UNESCO World Heritage Site, Preah Vihear Temple, is a detour north from the route, approximately 100 km from the NR5, but not directly on the way.

Driving in Cambodia requires caution due to motorbikes, livestock, and occasional roadworks. Ensure your vehicle insurance covers both countries and carry a first-aid kit.

For families, rest stops with playgrounds are rare; however, larger gas stations like PTT (Thai side) and Sokimex (Cambodian side) offer clean restrooms and snack shops. In Cambodia, the Angkor Wat complex is a major family-friendly attraction, though it's a detour if heading directly to Kampong Thom.

Pets are generally allowed in vehicles, but crossing borders requires an international health certificate and rabies vaccination records. Keep your pet leashed at rest stops.

Plan rest every 2-3 hours: recommended stops include a coffee break in Sa Kaeo (Thailand) and a lunch in Sisophon (Cambodia), where you can try local Khmer cuisine.

For hidden off-route spots, consider the Prasat Bakan temple ruins near Wat Phnom, about 20 km south of the highway, offering a quiet alternative to busy Angkor.

Given the moderate distance and border hassle, is it worth driving Chon Buri to Kampong Thom? Yes, if you value flexibility and off-the-beaten-path experiences.

Start by taking Route 3 (Sukhumvit) south from Chon Buri, then merge onto Route 33 towards Aranyaprathet. After crossing the border, continue on National Road 5 (NR5) eastward to Kampong Thom via Sisophon and Siem Reap bypass.

• Road quality: Thai highways are well-paved; Cambodian roads vary from good to rough patches near construction zones.
• Fuel availability: Frequent gas stations on Thai side; in Cambodia, stations in major towns (Poipet, Sisophon, Siem Reap) are reliable.
• Border procedures: Prepare passport, vehicle documents (if driving your own car), and expect ~1-2 hours for formalities.
• Tolls: No tolls on Thai side; Cambodian NR5 has small tolls (approx. $1-2).
