Vientiane to Savannakhet Road Trip Guide

This 457-kilometer drive on National Road 13 (Route 13) typically takes 7–9 hours by car, not counting rest stops. The road follows the Mekong River’s east bank, passing through flat farmland and occasional limestone karst outcrops. It’s a key artery connecting Laos' capital with the southern provinces, carrying heavy truck traffic.

The route's flat topography means no mountain passes, which keeps driving times predictable. However, the road's condition varies: the northern stretch is well-paved, while the southern part suffers from potholes and narrow shoulders. You'll cross several major tributaries of the Mekong, including the Nam Kading and Nam Theun rivers.

Given the long drive, plan rest breaks every 2–3 hours. Paksan and Thakhek are ideal overnights with hotels and restaurants. Many roadside stops offer Lao coffee and noodle shops, but for kids, the Lao Pako resort at the Nam Ngum reservoir (just off Route 13) provides a family-friendly pool and bungalows.

For families, restrooms are often squat toilets; carry your own tissues and hand sanitizer. Pet owners will find most guesthouses accept pets, but it's wise to call ahead. The flat terrain makes the drive easy for children, but pack entertainment as mobile data can be patchy.

Fatigue is a real risk due to monotonous driving. Use dedicated lay-bys for naps, and avoid driving at night when livestock and unlit vehicles are common. The road's safety record has improved, but remains cautious in the rainy season (May–October) when surface water can cause aquaplaning. Always check the weather forecast before setting out.

Fuel stations are plentiful along Route 13, especially in larger towns like Paksan and Thakhek. Expect to pay around 10,000–12,000 kip per liter for gasoline, with diesel slightly cheaper. There are no tolls on this road, but be prepared for police checkpoints, especially near provincial borders.

Driving is on the right side, and speed limits are 80 km/h on open roads, but lower through villages (40 km/h). Overtaking requires caution due to narrow lanes and heavy truck traffic. You must have a valid international driving permit and vehicle insurance. The use of seatbelts is mandatory for all passengers.

Just north of Paksan, the Nam Kading National Protected Area offers a jungle escape with waterfalls and hiking trails—a perfect short detour. Around Thakhek, the famous Thakhek Loop begins, featuring karst mountains, caves, and rural villages, though you'll only skirt its edge. Closer to Savannakhet, the That Ing Hang stupa, a significant Buddhist site, is a must-see.

For off-route spots, consider the Bualapha area with its coffee plantations and Hin Boun cave, accessible via a rough side road. But don't attempt this in the rainy season without a 4WD.

Local commerce thrives in roadside markets, where you can buy fresh fruits like mangoes and sticky rice. The region is known for its silk weaving, particularly in Ban Naphia, famous for 'Lao hai' jars. Don't miss the opportunity to taste Savannakhet's traditional 'khao pun' – a spicy rice noodle soup.
