Sattahip to Pursat Drive Guide: Routes, Stops & Safety Tips

The highway from Sattahip, home to Thailand's main naval base, to Pursat, a Cambodian provincial capital on the banks of the Pursat River, crosses the Cardamom Mountains' eastern foothills. This route is less traveled than the Bangkok-to-Poipet corridor, offering a quieter perspective on the Thai-Cambodian border. At the Ban Laem–Daun Lem crossing, the Khao Luk Chang viewpoint offers a sweeping panorama that sets the tone for the journey.

The primary route uses Thailand's Highway 314 (Sattahip–Ban Bueng) and Highway 344 (Chonburi–Klaeng), then continues on National Road 3 (Route 3) south to Ban Laem. After crossing into Cambodia via the Ban Laem–Daun Lem international checkpoint, you join National Road 57A and then National Road 5 toward Pursat. The entire Thai stretch is paved and well-maintained, while Cambodian roads are generally good but narrower, with occasional potholes near construction zones.

• Driving time: 5–6 hours excluding border stops, depending on traffic and weather.
• Border crossing: Ban Laem (Thailand) to Daun Lem (Cambodia) is open daily from 6:00 to 22:00 (Thai time).
• Vehicle insurance: Thai compulsory motor insurance ceases at the border; purchase Cambodian third-party insurance (about $10 for a week) at the crossing.
• Fuel: Petrol stations are abundant on the Thai side; in Cambodia, stations cluster along Route 5, but it's wise to fill up before leaving Thailand as rural stretches have scarce options.

The Thai segment is generally smooth, but the Cambodian stretch requires patience for overtaking slow trucks and farm vehicles. Speed limits: 90 km/h on Thai highways, 80 km/h on Cambodian National Road 5. Seat belts are mandatory, and child car seats are recommended, though often unavailable in rental cars. For families, the Khao Khitchakut National Park in Chanthaburi offers easy nature trails and a waterfall picnic spot, but it adds about an hour to the drive. Pet-friendly options are limited; consider bringing a travel crate and check with hotels in advance as many rural guesthouses are not equipped for pets.

Fatigue management is critical: plan rest stops every 2 hours. The PTT petrol station at Klaeng (Thailand) has a clean food court and restrooms, while the Cambodian border area has basic eateries. If you need a longer break, the city of Chanthaburi has riverside cafes and a cathedral. For hidden off-route spots, the O'Smach border market (reachable via a detour on Route 68) offers a unique cross-cultural shopping experience but extends the journey significantly.

Yes, if you enjoy scenic landscapes and a less commercialized border, but factor in the extra time and road conditions.

The route transitions from the coastal plains of Chonburi through the rubber and cassava plantations of Chanthaburi and Trat, then ascends into the forested foothills of the Cardamom Mountains. The Khao Soi Dao Wildlife Sanctuary is visible from the highway, but a side trip to the sanctuary's nature trails requires a detour of about 30 km. Cambodian roadside markets offer local fruits like durian and mangosteen, while Sattahip's fresh seafood is a must-try before departure.

Pursat is known for its marble carving and traditional Khmer silk weaving. The Pursat River runs through the town, and the nearby Phnom Kulen National Park, a sacred mountain with waterfalls and ancient temples, is a designated UNESCO World Heritage Site. However, the park is a few hours' drive north of Pursat, so include it only if you have extra time. For a quick cultural touch, Wat Sampov Meas in Pursat town offers a glimpse of local Buddhist practices.
