Samut Songkhram to Suong: Road Trip Guide

The Samut Songkhram to Suong route begins in Thailand's coastal province of Samut Songkhram, crossing into Cambodia to reach the town of Suong. This drive spans approximately 450 kilometers, and the journey combines bustling highways with serene countryside. One notable driving quirk: the route crosses the border at the Aranyaprathet/Poipet checkpoint, where traffic can be heavy, and you'll switch from driving on the left in Thailand to the right in Cambodia (though Cambodian roads often have mixed traffic patterns).

As you depart Samut Songkhram, the flat delta gives way to sugarcane and rice paddies. You'll pass near Thailand's Thungyai-Huai Kha Khaeng Wildlife Sanctuaries, a UNESCO World Heritage Site, though these are further north, not directly on the route. A better-accessible natural stop is Khao Yai National Park, a few hours off-route, known for its waterfalls and wildlife.

Upon entering Cambodia, the landscape turns to semi-arid plains and traditional stilt houses. In Suong, a thriving market town in Tbong Khmum Province, you can experience local commerce at the morning market and try regional specialties like prahok, a fermented fish paste. Street food stalls are common, offering affordable meals for travelers.

For family suitability, the route offers ample snack stops and restrooms at petrol stations, though Cambodian roadsides have fewer family-friendly facilities than Thailand. Pets are easier to manage on the Thai side, where some hotels and attractions are pet-friendly; in Cambodia, keep pets on a leash and check ahead.

The primary route follows Thailand's Route 33 (AH19) from Samut Songkhram east through Nakhon Pathom, Suphan Buri, and Sa Kaeo, then across the border to Cambodia's National Highway 1 to Suong. The border crossing at Aranyaprathet/Poipet is open from 6 AM to 10 PM, and you'll need to arrange a Cambodian visa in advance or at the border.

Fuel costs are lower in Thailand than in Cambodia, so fill up before crossing. Toll fees on the Thai side are modest, about 100 baht total. Driving times can increase significantly during Cambodian holidays when traffic through Poipet swells.

• Route: Route 33 (Thailand) then NH1 (Cambodia)
• Border crossing: Aranyaprathet/Poipet
• Toll fees: ~100 THB total on Thai highways

Road quality is good on Thai highways, with well-marked lanes and regular patrols. In Cambodia, NH1 is two-lane with some potholes, so drive carefully, especially in heavy rain during the monsoon (May-October).

For rest zones, Thailand has numerous service areas; plan to stop every two hours to avoid fatigue. In Cambodia, rest stops are sparser, so use petrol stations.

Hidden off-route spots include the Prasat Ta Muen Thom temple ruins near the border, an offbeat archaeological site, and the Samut Songkhram riverside markets before you start.
