Koh Rong to Saraburi Road Trip: Routes, Stops & Tips

Leaving the turquoise waters of Koh Rong, your road trip to Saraburi begins with a 4-hour ferry to Sihanoukville, followed by a 10-hour drive across Cambodia and Thailand. The total journey spans roughly 800 kilometers, crossing two international borders and ending in Thailand's central rice basket.

The route passes through Phnom Penh, Poipet, and Bangkok before reaching Saraburi, where the famous Khao Yai mountains rise to the east. Expect a mix of highways and local roads, with the Thai section offering smoother asphalt and well-marked intersections.

Before you set out, ensure your passport has at least six months validity and check current visa requirements for Cambodia and Thailand. Carry an International Driving Permit, as your home license alone may not suffice.

As you leave Cambodia, the Cardamom Mountains dominate the horizon, their dense rainforests giving way to flat, agricultural plains near the Thai border. In Thailand, the landscape transforms into rice paddies and sugarcane fields, with the Khao Yai National Park—a UNESCO World Heritage Site—lying a short detour east of Saraburi.

Climatically, the best time to drive is from November to February when temperatures average 25°C and humidity drops. Avoid the monsoon months of June to October, when heavy rains can cause flooding and slippery roads.

Local commerce thrives along the route: in Cambodia, fresh fruit stalls offer durian and mangosteen; in Thailand, roadside markets sell sweet tamarind and handwoven textiles. For a unique experience, visit the night market in Aranyaprathet, just across the Thai border, renowned for its local crafts.

Hidden gems include the Banteay Chhmar temple complex in Cambodia, far less crowded than Angkor Wat, and the Chet Khieu waterfall in Khao Yai, accessible from Saraburi in under an hour.

Infrastructure safety is solid on Thai highways, but in Cambodia, watch for motorbikes, livestock, and unmarked speed bumps. Both countries drive on the right, and speed limits are 90 km/h on highways. Use rest areas every two hours; recommended stops include the O'Smach gas station in Cambodia and the Wang Chan coffee shop in Thailand.

Fatigue management is crucial for a drive this long, so plan overnight stays in Phnom Penh and Bangkok. For families, the Playground Cafe in Phnom Penh offers a safe play area, while the Ferrari Fun Park in Bangkok is a hit with kids. Pet-friendly options are scarce, but the Dog House Hotel near Pak Chong allows dogs in designated rooms.

Culinary infrastructure is varied: from street stalls in Phnom Penh to upscale restaurants in Bangkok. In Saraburi, don't miss the local boat noodles at Rot Det Noodle Alley. For a quick bite, 7-Eleven stores are ubiquitous in Thailand, but rare in Cambodia, so stock up accordingly.

When nature calls, clean restrooms are found in most Thai gas stations, but in Cambodia, be prepared for squat toilets. Carry your own toilet paper and hand sanitizer.
