Road Trip Guide: Fang to Kalasin – Scenic Drives & Hidden Gems

This 700-kilometer journey from Fang in Chiang Mai Province to Kalasin in the Northeast begins in the shadow of Doi Ang Khang, where the road climbs past orchards and hill tribe villages before descending into the Ping River Valley. The route traverses two distinct geological zones: the granite peaks of the Thai Highlands and the sandstone plateau of the Khorat, which you'll enter after crossing the Phetchabun Range.

Notably, Route 107 from Fang to Chiang Mai is a winding two-lane road with frequent sharp curves, while the later sections on Highway 1 and 12 are smoother and straighter. The trip typically takes 10-12 hours of driving time, but plan for a full day with rest stops.

The route passes near two UNESCO World Heritage Sites: the historic town of Sukhothai, with its ancient temples and Buddha images, and the Ban Chiang archaeological site near Udon Thani, known for its prehistoric pottery. A detour to either adds a day but enriches your understanding of Thailand's heritage.

Climatic conditions vary drastically: the mountains near Fang are cool, with average temperatures of 15°C in the morning, while the plateau around Kalasin can exceed 35°C in April. The best time to drive is from November to February, when the weather is dry and mild.

Local commerce thrives along the way: Don't miss the morning market in Phitsanulok for local snacks like khao soi and sai ua. The roadside stalls near Lom Sak offer fresh fruit, especially tamarind and mango. In Kalasin, try the famous Phu Thai woven silk at local cooperatives. These purchases support village economies.

Infrastructure safety is generally good, but be cautious on routes 107 and 12, which have sharp curves and occasional landslide debris. Always wear seat belts, and use low-beam headlights in the daytime for visibility. The speed limit on highways is 90 km/h, but reduce to 50 km/h in towns.

For families, the route offers several child-friendly stops: the Mae Tho Waterfall near Fang, the Siam Country Farm in Chiang Mai (a bit off-route), and the dinosaur museum in Kalasin. Restrooms are available at these attractions, and some have playgrounds.

Pet-friendly frameworks are limited, but many roadside restaurants allow pets on outdoor seating. Carry a pet crate for rest stops, and bring water and food for your animal. Hidden off-route spots: the Phu Langka viewpoint, 5 km from Route 12, offers a stunning sunrise without crowds.

Fatigue management is crucial on this long drive. Plan rest stops every 2 hours at designated rest areas, such as the one near Lampang (3-hour mark) and at Khon Kaen (9-hour mark). Take a 15-minute nap if you feel drowsy, and switch drivers if possible. Use energy-boosting music or podcasts.

Fuel stations are sparse in the mountainous sections, so fill up in Fang or Chiang Dao before tackling the curves. The cost of gasoline averages 35 baht per liter (as of 2025), and with a fuel economy of 10 km/l, expect to spend around 2,450 baht on fuel for the entire trip.

Tolls are only applicable on the elevated highway around Bangkok, but the route avoids the capital entirely. Road surfaces are generally well-maintained, but sections of Route 107 and Route 12 through the mountains may have potholes after heavy rains.
