Kep to Ha Tien Road Trip Guide: Scenic Stops & More

The drive from Kep to Ha Tien covers 105 km along Cambodia's southern coast via National Road 33 and into Vietnam's Kien Giang province. The border crossing at Prek Chak/Xa Xia is typically straightforward, with both countries' formalities handled within an hour on weekdays.

This route shifts from Cambodia's quiet fishing villages to Vietnam's bustling port town in under 2.5 hours of drive time, offering a masterclass in coastal transition. Along the way, you'll pass through the Kampot pepper country, limestone karsts, and the coastal gem of Kampong Trach.

The road conditions are generally good, though you'll encounter occasional potholes near construction zones. A 2019 upgrade to the Cambodian stretch smoothed most of the pavement, but it's still a two-lane highway where overtaking requires caution.

Just 10 km south of Kep, you'll find the Phnom Chhngok cave with its 8th-century brick temple hidden inside a limestone cave. The entrance fee is $2, and the short climb offers panoramic views of the surrounding rice paddies.

For a detour, Kampot's riverside promenade is 15 km west of the main route and is ideal for a coffee stop at one of the many riverside cafés. The Kampot pepper farms, like La Plantation, offer tours where you can taste fresh peppercorns and learn about the coveted Kampot pepper.

Is it worth driving Kep to Ha Tien just for the scenery? Absolutely, especially if you enjoy dramatic karst formations. The standout feature is the Kampong Trach area, where razor-sharp limestone cliffs tower over lotus ponds and rural villages. The local market there sells fresh durian and mangosteen in season.

• Kep's crab market is the perfect starting point, with fresh blue crabs and local squid.
• In Ha Tien, the night food market along the canal serves fresh oysters and the famous bánh xèo (Vietnamese pancakes).
• Local fisheries in the region produce fish sauce the traditional way - you can smell it before you see it.

This route skirts the edge of the Mekong Delta's UNESCO-listed forests, but the nearest UNESCO site is Preah Vihear temple, over 400 km away. However, the region's intangible cultural heritage - like the old Chinese shophouses in Ha Tien's town center - offers a glimpse into the area's history without the crowds.

Road quality varies: freshly paved in Cambodia, with a few rough patches after the border. In Vietnam, the surface is good but narrow, and you'll share it with motorbikes and bicycles. Watch for unmarked cattle crossings, especially near dawn and dusk.

For families, the route is quite manageable. Kep's butterfly garden is a hit with kids, and the Kampong Trach caves offer safe exploration. Pack snacks and water, as restaurants are sparse between the border and Ha Tien.

Pet-friendly? Yes, but with caveats: Cambodian guesthouses are generally okay with small pets, but Vietnamese hotels often have restrictions. Bring a pet carrier and check policies ahead.

To fight fatigue, build in regular breaks. The best planned rest stops are at Kompong Trach's floating village café and the pre-border market at Prek Chak. Both have shaded seating and cold drinks. For a hidden gem, take a 5-km detour to the Thạch Đồng Cave near Ha Tien, which has a serene pagoda and is far less touristy than Phu Quoc.

Fuel is cheaper in Cambodia than in Vietnam, so top up before crossing. As of 2025, gasoline in Cambodia costs about 4,600 riel per liter ($1.13), while in Vietnam it's around 23,000 VND per liter ($0.95) - surprisingly, Vietnam is actually cheaper now due to recent tax cuts. Consider your refueling point accordingly.

The total fuel cost for the journey is roughly $8-10 for a standard sedan, depending on traffic. No tolls on the Cambodian side; in Vietnam, there's a small bridge fee of 20,000 VND ($0.80) at the Ha Tien bypass.

• Border crossing hours: 06:00 - 22:00 daily.
• Visa on arrival: Available for many nationalities; have cash USD for fees.
• Vehicle insurance: Ensure your Cambodian insurance covers Vietnam, or buy temporary coverage at the border.

How long to drive Kep to Ha Tien? The Google Maps estimate is 1 hour 45 minutes without stops, but plan for 2-3 hours if you include photo stops, border formalities, and snacks. In Cambodia, you'll follow NH 33 south past Kampot; after the border, the road becomes QL 80 in Vietnam.
