Phu Quoc to Kep: Essential Road Trip Guide & Stops

The ferry from Phu Quoc to Kep takes you across the Gulf of Thailand, a route steeped in Khmer and Vietnamese maritime history. The crossing itself reveals the dramatic shift from Phu Quoc's tropical white-sand beaches to the limestone karsts of Kampot Province. You'll land at Kep Beach, a former French colonial seaside resort whose crab market still sets the town's culinary pace.

This guide covers every practical angle: driving times, fuel costs, child and pet suitability, and the finest stops between islands. We've structured it so you can skim for specifics or read end-to-end for a complete picture.

Skip the generic advice and get the real distances, road numbers, and prices. Whether you're a family with toddlers or a solo traveler with a dog, this route has options—but they differ wildly.

The journey begins at Phu Quoc's Bai Vong Port, where Superdong and Phu Quoc Express operate daily ferries to Ha Tien on the mainland. From Ha Tien, you'll take National Road 80 north to the Cambodian border at Xa Xia, then continue on Cambodian National Road 2 through Kampot to Kep. The total road distance is roughly 120 km, with the border crossing adding 30–60 minutes depending on traffic.

Fuel prices differ between Vietnam and Cambodia; as of 2025, petrol in Cambodia is about 4,000 KHR (~$1.00) per liter, while in Vietnam it's around 28,000 VND (~$1.15) per liter. Fill up in Vietnam before crossing to save money, but note that many rental cars are not allowed to exit Vietnam in the first place—check your rental agreement.

The drive from Ha Tien to Kep itself is smooth: NH80 is a two-lane asphalt road with moderate truck traffic, while Cambodia's NH2 is well-maintained but narrow in places. You'll pass through rice paddies and pepper farms, with occasional wildlife crossings (cattle, motorbikes).

• Ferry tickets: roughly 300,000–350,000 VND per person (about $13–15) for the 2-hour crossing.
• Vehicle transport: adding a car to the ferry costs around 200,000–300,000 VND extra, but only if the rental company allows it.
• Border crossing: Vietnamese side is open 7:00–22:00; Cambodian side 7:00–20:00. Bring your passport and vehicle documents.
• Toll roads: none on this specific route; only border fees (~$30 for a vehicle permit).

Phu Quoc is dominated by tropical monsoon forests and coral reefs, while Kep is famed for its crab shacks that line the waterfront. Inland, the road between Ha Tien and Kep cuts through the Kampot salt fields and pepper plantations—two of Cambodia's most iconic agricultural products. The climate shifts from Phu Quoc's two seasons (dry Nov–Mar, wet May–Oct) to the more stable microclimate of Kampot Province, which is cooler due to the surrounding Elephant Mountains.

UNESCO has twice listed the Preah Vihear temple complex, but that's far north; closer to your route are the Preah Monivong Temple and Kep's butterfly farm, neither of which are UNESCO heritage sites. The only UNESCO site nearby is the ancient city of Angkor—over 300 km away, so don't plan a detour.

Local trade thrives on seafood: Phu Quoc exports fish sauce and peppercorns, while Kep's market sells fresh crab, squid, and shrimp right off the boats. On the Vietnamese side, Ha Tien's morning market offers tropical fruits and cooked dishes that make excellent picnic supplies.

For natural beauty, stop at the salt fields of Kampot (visible from the road) or the Kep National Park, where a hiking trail leads to a hilltop viewpoint over the ocean. The limestone caves near the border are less visited and require a local guide.

Road quality: Vietnamese NH80 is patrolled and lit near towns, but the Cambodian NH2 has stretches without streetlights—night driving is not recommended. Animals and slow-moving tractors are common, so keep your speed under 60 km/h. Seat belts are mandatory in both countries, and child car seats are rarely provided by rental companies, so bring your own.

Families: The ferry has indoor seating and restrooms, but no dedicated play areas. On the road, stop at the Krong Kep Roundabout (near the crab market) where kids can run safely in the open square. The Kep National Park's staircase is steep; better for older children. For younger ones, the 'Kep Beach' has calm, shallow water.

Pets: Crossing the border with a pet requires an import permit from Cambodia (available at the border); Vietnam also requires a health certificate. Plan ahead. The ferry allows pets on deck as long as they are leashed and muzzled.

Fatigue management: The drive is short but the ferry crossing can be tiring. Identify rest stops: O Keo village (km 15 on NH2) has a coffee shop; Kampot city (the 'Kampot Riverside' area) is a natural breakpoint with cafes. The journey from Ha Tien to Kep is under 3 hours of actual driving, so fatigue is unlikely if you take a 15-minute break at the border and again at Kampot.

Hidden off-route spots: The village of Kratie? No—that's far east. Instead, just before Kep, turn onto the unpaved road to Rabbit Island (actually a 20-minute boat ride from Kep pier) for an empty beach. On the Vietnamese side, the 'Phu Quoc Prison' museum is a detour off the main road, but historically significant.
