Phnom Penh to Kampong Cham: A Detailed Road Trip Guide

Phnom Penh to Kampong Cham is a 120-kilometer journey along National Road 7 (NR7), one of Cambodia's primary eastbound arteries. The route crosses the wide Tonlé Sap floodplains, then enters the rolling terrain of the Cambodian heartland, passing through small towns and agricultural districts. Before the road was fully paved in the 2010s, the trip could take six hours; today, it's a two-to-three-hour drive, depending on traffic and the number of stops you make.

This route is a microcosm of Cambodian modern life: you'll see colorful markets, rubber plantations, and the 'krama' scarf-weaving villages near Skun. The drive is a practical choice for travelers heading to the riverside town of Kampong Cham, known for its bamboo bridge and French colonial architecture.

Below is a quick overview of the journey:

The entire route is a well-maintained two-lane asphalt road with clear lane markings and several fuel stations. Petrol prices in Cambodia hover around 4,000 riels (about $1) per liter – a full trip will consume roughly 12-15 liters in a standard sedan, costing $12-15. You'll pass highway markers every 20 kilometers, but the most useful landmarks are the best stops you can identify using a route planner.

There are two major bridges along the way: the Kizuna Bridge over the Mekong River, which leads into Kampong Cham city, and several smaller spans over the Chinit River. The road toll is zero – it's a public highway. Mobile coverage is consistently strong, but it's wise to download offline maps if you'll be exploring side roads.

• Road surface: 100% paved (as of 2024)
• Speed limits: 60-90 km/h (urban 60, rural 90)
• Fuel stops: Many, including Caltex and local stations
• Emergency services: Reachable via 117 (police) or 119 (fire/ambulance)

Road conditions are generally good, but watch for livestock crossings and motorbikes overtaking unexpectedly. The highway has a well-marked centerline, though some sections have soft shoulders. For families, there are several rest areas with shaded picnic spots near Skun and Chhouk Meas pagoda, about 20 km before Kampong Cham. These are safe and well-trafficked, making them ideal stops for children to stretch their legs.

For pet owners, many restaurants with outdoor seating welcome dogs on leashes. The petrol stations along NR7 often have green spaces where you can take a short walk with your pet. However, there are no dedicated pet rest areas, so plan your breaks accordingly.

Fatigue management: Take a break every 90 minutes. The drive can feel hypnotic due to the flat terrain, so schedule stops at the 1.5-hour mark. Recommended stops: Toul Prom Market (around km 50) for a coffee, and the Crocodile Farm near Kampong Siem (around km 80) if you're traveling with kids – it's a brief detour that showcases local wildlife.

Just outside Phnom Penh, the road parallels the Tonlé Sap floodplain, where you'll see wet rice terracings and lotus ponds. Near Prek Kdam (around kilometer 15), there's a large ferry dock – an active river crossing that carries vehicles and foot traffic. The landscape transitions to sugar palm savanna as you approach Skun, then shifts to rubber and cashew plantations further east.

Skun is famous for its spiders (a deep-fried delicacy) at the bustling market near the roundabout. From January to April, the central highlands around Kampong Cham erupt with cotton rose (ambarella) trees, adding a pink hue to the road. The climate is tropical monsoon – expect heavy rains from May to October and a hot, dry season from November to April, with temperatures ranging from 25°C to 35°C.

The region is rich in local commerce: roadside stalls sell fresh coconuts, bananas, and sometimes durian during its season. Around 10 kilometers before Kampong Cham, you'll encounter the bamboo bridge (a temporary structure) that connects the city to the eastern bank of the Mekong each dry season – a unique cultural and engineering spectacle that has been rebuilt annually since 1997.
