Uthai Thani to Kampong Cham: Road Trip Guide

Crossing from Thailand to Cambodia, the 520 km route from Uthai Thani to Kampong Cham follows National Road 1 (NR1) in Thailand, becoming the A1 in Cambodia. Unlike the bustling Bangkok-to-Poipet corridor, this drive offers a quiet transition from the central Thai plains to the Mekong riverfront.

The border checkpoint at Aranyaprathet/Poipet is the main entry point, where visa-on-arrival for Cambodia is available for most nationalities. The entire journey typically takes 8-10 hours, depending on border wait times and road conditions.

The Thai portion (NR1) is a well-paved, four-lane highway with frequent fuel stations and rest stops. After the border, the A1 in Cambodia is a two-lane highway, with sections under improvement; fuel stations are sparser, especially between Sisophon and Skun, so fill up at Poipet.

Fuel prices in Cambodia average lower than Thailand (as of early 2025), but currency exchange rates favor Thai baht at border shops. Plan for tolls: the Thai side has no tolls on this route, but consider the cost of a Cambodian e-visa ($36) and possible unofficial fees at the border.

• Distance: 520 km total.
• Time: 8-10 hours driving plus border crossing.
• Border hours: 7am-10pm, both countries.
• Petrol stops: Every 50-80 km in Thailand; every 100+ km in Cambodia after Sisophon.
• Tolls: None on Thai side; Cambodian road fees included in vehicle entry unless using a local shuttle.

Thai road conditions are excellent, but Cambodian A1 has unlit stretches and heavy motorbike traffic; drive with headlights on even during the day. The route is suitable for families with children, provided you plan rest breaks; child seats may require bringing your own, as rental options are rare.

For fuel and rest stops, the PTT station at Ban Khok Sung (Thai side) and the modern Sokimex complex at Sisophon (Cambodia) offer clean restrooms and kid-friendly snack areas. For pet-friendly travel, note that Cambodia requires a valid rabies vaccination certificate; many border officials request it, though enforcement is sporadic.

Fatigue management is critical: the monotonous Cambodian plains contribute to driver drowsiness. Plan to stop every two hours; coffee, a short walk, or a nap in a hammock (available at many roadside cafes) helps.

• Recommended rest zones: Aranyaprathet Friendship Park (Thai), O'Chrouh market near Sisophon, and the Mekong Viewpoint at Kampong Cham.
• Emergency contacts: Cambodia's road police hotline 117, ambulance 119.

The route's landscape shifts from rice paddies and sugar palm savannas in Thailand to the flat, green plains of northwestern Cambodia, dotted with lotus ponds and rubber plantations. The most striking natural stop is the Phnom Pros and Phnom Srei hills near Kampong Cham, offering panoramic views of the Mekong.

Hidden off-route, the Wat Nokor Bachey temple in Kampong Cham merges ancient shrine and modern pagoda, while the bamboo bridge across the Mekong (seasonal) is a local engineering marvel worth a detour.

Local commerce thrives along A1: roadside stalls in Cambodia sell tropical fruits, grilled meats, and the famously bitter iced coffee.

• Key stops: Khan Kror Sang market at the border, Skun's fried spider stalls (for the daring), and the Kampong Cham night market for souvenirs.
