Hoi An to Kampong Cham: A Road Trip Guide

The road from Hoi An to Kampong Cham crosses two countries and a border at Moc Bai, passing through the Central Highlands of Vietnam and the flat Mekong plains of Cambodia. It's a drive of approximately 500 miles, taking about 12 hours without stops, but you'll want to stretch it over two or three days. The journey begins near the UNESCO-listed town of Hoi An, follows National Route 1A south to Ho Chi Minh City, then continues on National Route 22 to the border, before joining Cambodia's National Route 1 to Phnom Penh and finally turning north on Route 7 to Kampong Cham.

The route is a study in contrasts: the lush, mountainous Hai Van Pass, the bustling energy of Saigon, the rubber plantations of the highlands, and the vast, rice-filled plains of Cambodia. The rainy season (May to October) brings heavy afternoon downpours and flooded roads, while the dry season (November to April) offers clearer skies and cooler mornings.

Road quality varies: Vietnam's National Route 1A is mostly paved but can be crowded with trucks and motorbikes, especially near cities. Cambodia's roads are two lanes and often lack shoulders; potholes are common. Drive defensively, avoid night driving, and use headlights during rain.

For families, the journey is doable with stops at child-friendly attractions. In Vietnam, the beach at Mui Ne, the water park in Da Nang, and the Zoo in Ho Chi Minh City offer breaks. In Cambodia, the Mekong island of Koh Paen near Kampong Cham offers cycling and picnic spots.

Pet-friendly travel is limited on this route; many hotels in Vietnam and Cambodia accept pets, but border crossing paperwork requires a health certificate and rabies vaccination. Plan ahead.

To combat fatigue, rest every 2-3 hours at designated rest stops or popular cafes. In Vietnam, these are common in towns like Quy Nhon and Nha Trang; in Cambodia, rest areas near Neak Luong bridge. Hidden off-route spots like the elephant sanctuary at Yok Don National Park or the temples at Wat Hanchey near Kampong Cham are worth a detour.

This route passes several natural wonders. In Vietnam, the Hai Van Pass offers sweeping views of the coast, while the Central Highlands near Buon Ma Thuot feature volcanic landscapes and waterfalls. In Cambodia, the drive from Phnom Penh to Kampong Cham is flanked by rice paddies and sugar palm trees, occasionally forming natural canopies.

UNESCO World Heritage Sites along the way include Hoi An Ancient Town, My Son Sanctuary (a short detour), and Phong Nha-Ke Bang National Park (if you venture north). In Cambodia, the temple complex of Wat Nokor near Kampong Cham dates back to the 11th century.

Local commerce thrives at roadside markets where you can buy tropical fruits, woven textiles, and simple meals. In Vietnam, try cao lầu in Hoi An and banh mi in Ho Chi Minh City. In Cambodia, sample amok (coconut fish curry) and kralan (sticky rice in bamboo).

Navigating this route requires planning for border crossings, fuel stops, and rest areas. The main border crossing is at Moc Bai (Vietnam) / Bavet (Cambodia), open from 6:00 to 22:00. You'll need a valid passport and visa; e-visas are available for Cambodia. Fuel is readily available in Vietnam, but in Cambodia, stations are sparser, especially east of Phnom Penh. It's wise to fill up before crossing into Cambodia.

• Border crossing: Moc Bai/Bavet, open 6:00-22:00, e-visa accepted.
• Drive time from Hoi An to Kampong Cham: 12-14 hours, spread over 2-3 days.
• Fuel cost estimate: $70-90 for the entire trip.
• Toll roads: Vietnam has tolls on National Route 1A, about $7 total.
