Trat to Prey Veng Drive: Stops, Costs, and Family Tips

The drive from Trat to Prey Veng is a 200-kilometre corridor linking Thailand's eastern seaboard with Cambodia's southern plains, yet it remains overshadowed by the busier Aranyaprathet crossing. The route traverses the Cardamom Mountains' foothills, crosses the border at Hat Lek, and finishes on the flat, rice-growing expanse of Prey Veng province. This is not a highway of grand monuments, but of working landscapes—rubber plantations, cashew orchards, and the Mekong's slow-moving distributaries.

One quirky fact: the border at Hat Lek is one of Thailand's most easterly crossings, and it sees far less traffic than Poipet, which means shorter queues but fewer services. The road itself is a patchwork of Thai highway 318, Cambodian National Route 3, and local roads that change personality with every province.

The journey starts in Trat, a province known for its fruit orchards and 52 offshore islands. From the city center, take Highway 318 southeast to the coast, then follow the coastal road to Hat Lek. After crossing the border, the road becomes Cambodian National Route 3, a two-lane asphalt road in decent condition, which eventually connects to the Mekong ferry at Neak Luong and continues to Prey Veng town.

Border crossing formalities are straightforward: Thai exit and Cambodian entry visas are processed at the same checkpoint, and the whole process typically takes 30–45 minutes. Exchange money at the border for better rates; Cambodian riel and US dollars are widely accepted.

• Fuel: Beyond Trat, petrol stations become sparse until you reach the Cambodian town of Cham Yeam (about 10 km from the border) or Kampong Trach (30 km further). Fill up in Trat to avoid range anxiety.
• Toll costs: No tolls on this route, but you'll pay for the Neak Luong ferry (approx. $1 per vehicle) if you don't use the new bridge.
• Road condition: Thai roads are well-paved; Cambodian sections range from good to fair, with occasional potholes near villages.

The route's scenery transitions from the lush, green hills of Trat's interior to the flat, pastoral plains of Cambodia. Along the way, you'll pass through the Kampong Trach district, famous for its limestone karst formations and the Phnom Chhnork cave temple, a hidden gem not to be missed. Further south, the pepper farms of Kampot province are a short detour, but on the main route, you'll find rubber plantations and cashew orchards.

One UNESCO World Heritage Site is within a day's drive: the pre-Angkorian temple complex of Sambor Prei Kuk, located about 200 km north of Prey Veng. While not on the direct route, it's a feasible side trip for those with time. But this guide focuses on the direct drive.

Local commerce flourishes at roadside markets, especially around the border and in Kampong Trach. Here you can buy fresh tropical fruits, Cambodian palm sugar, and locally woven krama scarves. The culinary infrastructure includes simple noodle shops and BBQ stalls near the border, but as you get closer to Prey Veng, you'll find more diverse Khmer restaurants serving fish from the Mekong and the signature samlor machu (sour soup).

The climate along the route is tropical monsoon: November to February is cool and dry, making it the best time for driving. From March to May, temperatures can exceed 40°C, and the rainy season (June to October) turns some unpaved sections into mud pits.

Road safety varies significantly between the two countries. Thai roads are well-maintained and signed, but in Cambodia, you'll share the road with motorbikes, cattle, and sometimes unlit vehicles at night. Always drive defensively and avoid driving after dark if possible. Seatbelts are mandatory, and child seats are recommended but not widely available for hire.

For families, this route is moderately suitable. The border crossing can be hectic, and the ferry at Neak Luong offers a fun experience for kids. There are few dedicated playgrounds, but the open spaces near roadside restaurants allow children to stretch their legs. The best stops for families include the Phnom Chhnork cave (easy access) and the stilt houses along the Mekong near Prey Veng.

Pets are generally welcome in guesthouses and local restaurants, but keep them leashed and be aware of stray dogs.

To manage fatigue, plan stops every two hours. The border area has a cluster of rest stops with coffee and snacks, while Kampong Trach offers a proper meal break. A popular off-route spot is the Teuk Chhou Rapids, a series of natural pools near Kampot, perfect for a refreshing swim. However, building this into your trip adds at least an hour of driving.

Rest zones are limited on the Cambodian side, so use Thai petrol stations with clean facilities before crossing. Once in Cambodia, look for shops with shaded verandas, but expect squat toilets.

Overall, is it worth driving Trat to Prey Veng? Absolutely, if you're seeking a less-travelled border experience and don't mind a few rough edges. The best stops Trat to Prey Veng include the coastal viewpoints near Hat Lek, the pepper farms, and the riverfront promenade in Prey Veng town. For things to do between Trat and Prey Veng, consider visiting the gem markets of Pailin if you're willing to detour, but on the main route, the cave temples and fruit orchards are the highlights.
