Kampot to My Tho Road Trip: Best Stops and Driving Guide

The drive from Kampot to My Tho includes a border crossing at the Ha Tien – Xa Xia checkpoint, where the National Road 3 meets the Vietnamese QL80. The route totals roughly 280 kilometers, and the final stretch crosses the Mekong Delta on the My Thuan Bridge, which was the longest bridge in Southeast Asia when it opened in 2000. This two-country journey weaves through pepper farms, limestone karsts, and delta waterways, offering one of the most diverse road trips in the region.

Just east of Kampot, the limestone Bokor National Park looms, but the open road offers views of the Elephant Mountains and the coastal plain. As you approach Ha Tien, the landscape flattens into rice paddies and shrimp farms. In Vietnam, the Mekong Delta reveals its network of canals and fruit orchards, especially around Cai Be, where floating markets thrive. Stop at a local diner for a bowl of hủ tiếu or num banh chok; both regions are known for their distinct noodle soups.

The climate here is tropical, with a dry season from November to April and a wet season from May to October. The best time to visit is during the dry season when the roads are drier and the skies are clearer, though the delta can be hazy. Local commerce along the way is vibrant: Kampot's salt fields and pepper farms, Ha Tien's seafood markets, and Cai Be's fruit stands showcase the region's bounty. You can easily pull over to buy fresh pineapple or rice paper, but remember to negotiate politely.

• UNESCO World Heritage Sites: none directly on the route, but the nearby Preah Vihear temple in Cambodia (a UNESCO site) is a significant detour northward if you have extra days.
• Hidden off-route spots: the Thạch Động Cave in Ha Tien and the floating village at Ba Dong are lesser-known and worth a short detour.

The roads are generally safe but require vigilance; watch for sudden lane changes, livestock, and pedestrians, especially in towns like Ha Tien and Cai Be. Among the best stops Kampot to My Tho are the quiet town of Châu Đốc (an hour detour) and the Sampov Pram cave near Kampot, both great for stretching legs. For families, the rides are mostly kid-friendly, but pack snacks and water as services can be sparse between towns. Pet owners should note that crossing borders with pets requires a health certificate, rabies vaccination, and an import permit from the destination country—prepare well in advance.

To fight fatigue, plan a break every two hours. Well-maintained rest stops are available at border areas and at the My Thuan Bridge entrance, with clean restrooms and cafes. Other rest zones are scarce, so use bathroom opportunities at gas stations and markets. As a general rule, never drive at night because lighting is poor and animals wander onto the roads. Always keep your documents accessible for border patrol checks, and if you're a solo traveler, let someone know your route before you leave.

Crossing the border usually takes 30 to 60 minutes, depending on queue length and paperwork. Both countries require a valid passport and, for many nationalities, a visa or e-visa; check your specific entry requirements well before departure. The Cambodian side, National Road 3, is well-paved and mostly flat, while the Vietnamese QL80 and QL1A are well-maintained but busier with trucks and motorbikes.

• Fuel costs: roughly 4,000–4,500 riel (1 USD) per liter in Cambodia; Vietnam prices are similar, around 24,000–25,000 VND (1 USD) per liter.
• Tolls on Vietnamese expressways: if you choose the QL60 towards Cai Lay to avoid My Tho city traffic, expect tolls of about 30,000–50,000 VND per car.
• Road tolls in Cambodia are generally limited to the Phnom Penh–Sihanoukville expressway, not this route.

The drive is worth it for the changing scenes—from Kampot's quiet riverside to the hustle of provincial towns. You can tackle the entire trip in a single long day, but many drivers break it up to explore.
