Chaiyaphum to Kampong Thom: Road Trip Guide

The route from Chaiyaphum to Kampong Thom spans roughly 500 kilometers across Thailand and Cambodia, crossing the border at Chong Bok (Thailand) and Trapeang Kriel (Cambodia). This land border is the only official crossing on this route, and it's a key point for drivers heading toward Siem Reap and beyond.

Chaiyaphum sits at the edge of the Khorat Plateau, an area known for its red soil and rolling hills, while Kampong Thom is a lowland province along the Sen River. The drive typically takes 8-10 hours including border formalities, and the route is increasingly popular among overland adventurers.

This guide covers the practicalities of the journey, from fuel stops to family-friendly breaks, and highlights what makes this drive unique.

Road safety is generally good, but exercise caution on Cambodian roads, especially at night when livestock often wander. The Cambodian side has fewer streetlights, and many drivers use high beams, which can be blinding. Always wear your seatbelt, and consider hiring a local guide if you're not familiar with the area.

For families, the route offers several kid-friendly stops: the O'Smach resort area has a water park, and the Kulen National Park (not to be confused with the sanctuary) features waterfalls and a riverbed of carved lingas, which children enjoy exploring.

Fatigue management is crucial on this lengthy drive. Plan to break every 2 hours. A good spot is the town of Phnom Dek, roughly halfway, where you can rest and grab a meal. There are also numerous roadside cafés between Anlong Veng and Kampong Thom, but stick to ones that appear busy.

Pets are generally allowed in cars, but some hotels in Cambodia have restricted policies. It's best to confirm in advance. For hidden gems, take a short detour to the remote temple of Preah Khan, located about 30 km north of Kampong Thom, which is seldom visited by tourists.

The route uses Thai Highway 225 from Chaiyaphum to Ubon Ratchathani, then follows the border road to Chong Bok. After crossing, Cambodian National Road 62 (NR62) leads through Anlong Veng and then connects to National Road 6 (NR6) toward Kampong Thom. Road conditions are generally good on the Thai side, with well-maintained highways and clear signage. In Cambodia, NR62 is paved but narrow in sections, while NR6 is a major artery with heavy truck traffic.

Fuel stations are plentiful on the Thai side, but once you cross into Cambodia, stations become sparser, especially between Anlong Veng and Kampong Thom. It's wise to fill your tank before crossing, as fuel prices in Cambodia are slightly higher and credit card acceptance is limited.

For those asking how long to drive Chaiyaphum to Kampong Thom, expect to spend at least 2 hours at the border during peak times. The border is open from 7 AM to 8 PM, so plan to arrive early to avoid delays.

• Thai side: Highway 225, then Route 2389 to Chong Bok.

The landscape shifts dramatically from the arid highlands of Chaiyaphum, with its limestone karsts and phu (hills) like Phu Laen Kha, to the dense cashew nut plantations and palm-dotted plains of central Cambodia. Near the border, the Dongrek Mountains form a natural barrier, and the descent into Cambodia offers panoramic views across the northern plains.

Just south of Anlong Veng lies the Kulen Promtep Wildlife Sanctuary, a critical habitat for the endangered Kouprey. While not a formal stop, the area is teeming with birdlife, and if you're lucky, you might spot hornbills along the road.

In terms of local commerce, Anlong Veng is a bustling border town with markets selling everything from Thai products to Cambodian handicrafts. Further along, Kampong Thom is known for its pepper farms and silk weaving. You can purchase these directly from local producers.

For the best stops Chaiyaphum to Kampong Thom, consider natural attractions like Preah Vihear (a UNESCO site, though it’s ~45 km off the main route) and the Samraong pagoda, which offers a glimpse into local Buddhist culture.
