Da Lat to Koh Rong: A Road Trip Guide

The road from Da Lat to Koh Rong spans over 400 kilometers, crossing the Central Highlands and the Cambodian border before ending at the Gulf of Thailand. This route descends from 1,500 meters elevation to sea level, transitioning from pine forests to tropical farmland.

Notably, the only UNESCO World Heritage Site along the path is the Temple Zone of Sambor Prei Kuk, located near Kampong Thom, Cambodia, a pre-Angkorian complex dating to the 7th century. Its brick sanctuaries are a detour of roughly 30 kilometers from the main highway.

Road quality varies: Vietnamese highways are well-paved with rest stops every 50 km, while Cambodian roads may have potholes and occasional livestock crossings. Always keep your headlights on and avoid night driving on unknown stretches.

For families, stop at the Suoi Tien Theme Park near HCMC, which offers water slides and cultural shows, a perfect break for children. Pet-friendly travelers will find that many mid-range hotels in Cambodia accept pets, but confirm in advance.

To manage fatigue, plan a break every two hours at designated rest zones like the Long Thanh rest stop (km 12 on CT01) or the Krabei Chrum rest area near Sihanoukville. These offer shade and food stalls.

Hidden gems include the Binh Quoi village outside HCMC, a maze of riverside paths and bonsai gardens, and the abandoned Silvertown ghost building near Kampong Som, popular among photographers.

How long to drive Da Lat to Koh Rong is around 9-10 hours driving plus a 45-minute ferry ride, so plan an overnight in Kampong Thom. Whether it's worth driving Da Lat to Koh Rong depends on your love for varied landscapes, but the journey itself offers glimpses of both countries' rural life.

To maximize your trip, consider these things to do between Da Lat and Koh Rong: visit the floating village of Prek Toal, tour the Kampong Khleang stilt village, or relax at the unspoiled Otres Beach before the ferry.

The most common route uses Highway QL20 from Da Lat to Dầu Giây, then connects to the Ho Chi Minh City – Long Thanh – Dau Giay Expressway (CT01). This toll road costs about 70,000 VND for cars and cuts travel time by 40 minutes compared to the old National Road 1A.

Crossing into Cambodia at the Moc Bai border checkpoint, you will join National Highway 1 and later Route 51 and 52 toward Sihanoukville, where ferries depart for Koh Rong. The Cambodian road sections are generally two-lane with varying asphalt quality, especially around Kampong Som.

Fuel economy: Fuel prices in Vietnam are around 23,000 VND/liter, while Cambodian gasoline costs slightly less at approximately 4,000 riel/liter. A typical sedan uses roughly 7 liters/100km, so the total fuel cost for the 520 km trip is about 35-40 USD. Budget an additional 50 USD for accommodation and meals if split over two days.

• Bring cash for tolls and Cambodian border fees (vehicle permit ~5 USD).
• Ensure your vehicle insurance covers cross-border travel.

Leaving Da Lat, the road snakes along Elephant Falls, a 30-meter cascade that is particularly powerful during the rainy season from May to November. Further south, the landscape opens to coffee and pepper plantations, where you can purchase premium Robusta beans at local farms.

A unique detour is the 'Crazy House' (Hang Nga Villa) in Da Lat, though it is a tourist magnet; instead, consider the silent forests of Ta Nung Valley, which offer a serene picnic spot. In Cambodia, the Mekong River crossings near Neak Loeung are served by ferries, a rustic experience that locals use.

For a taste of authentic local commerce, stop at the Cai Be floating market near My Tho, which operates daily from 3 AM to 9 AM. Here, boats laden with tropical fruits trade produce directly.
