Udon Thani to Mae Taeng: A Scenic Road Trip Guide

Leaving Udon Thani, the Route 2 highway stretches west across the Khorat Plateau, a flat expanse of rice paddies that gradually gives way to the forested foothills of the Phetchabun Mountains. This 560-kilometer drive to Mae Taeng, a district just north of Chiang Mai, is more than a simple transit; it's a journey through Thailand's agricultural heartland, historic kingdoms, and changing climates.

The first notable landmark is the town of Khon Kaen, 110 kilometers in, where the highway skirts the city limits and offers a convenient fuel and coffee stop. As you continue, the landscape shifts subtly, and the air becomes drier until you reach the UNESCO-listed Ban Chiang Archaeological Site, a detour that rewards with 5,000-year-old artifacts. The drive itself, under normal traffic, takes about 9 hours, but plan for 10 to 12 with stops.

The route follows Highway 2 west to Phitsanulok, then switches to Highway 11 via Lampang, finally joining Highway 1 into Chiang Mai and taking Route 107 north to Mae Taeng. Toll-free entire way, this is one of Thailand's most straightforward long drives.

Fuel is plentiful along the route, with PTT and Shell stations in every provincial town. Expect to pay around 30 baht per liter for gasoline, and a typical fuel cost of 1,500 baht for the entire trip. Alternatively, Compressed Natural Gas (CNG) is available in some trucks, but for cars, LPG is more common; however, most rental cars run on gasoline.

• Highway 2 has rest areas every 40-50 km with toilets, food stalls, and 7-Eleven stores.
• Phitsanulok is a major junction; consider it a lunch stop and if needed, a place to stay overnight.
• The route crosses the Nan River near Uttaradit, a scenic spot for a quick photo.
• Beyond Lampang, the road climbs into the mountains with sharper curves; maintain moderate speeds.

Road conditions are generally excellent, but in the mountain sections between Lampang and Mae Taeng, watch for steep gradients and frequent curves. During the rainy season (June to October), slippery roads are a hazard, and fog reduces visibility in the early mornings.

Rest stops are well-spaced; take a break every 2 hours to stretch. For parents, major rest areas like the one at Phitsanulok have playgrounds, and many restaurants offer high chairs. Pet owners will find that most roadside cafés tolerate well-behaved dogs on leashes, and some even provide water bowls.

• Use the 'Rest Area' signs on Highway 2; many have shaded picnic spots.
• If you need a short nap, find a 7-Eleven with a parking lot and set an alarm.
• During Thai public holidays, traffic can be heavy; depart early.

The journey transitions from the flat, sun-baked plateau to the lush, misty mountains of the north. As you leave Udon Thani, the horizon is a patchwork of emerald rice fields interspersed with tamarind and eucalyptus groves. Around Phitsanulok, the landscape becomes more undulating, with the first hills emerging

Khao Kho, a short detour from Highway 12, is a mountainous area known for its cold climate, seas of clouds, and commemorative park. If you're interested in how to find the best stops and hidden gems between cities, this is a prime example.

For those wondering about is it worth driving Udon Thani to Mae Taeng, the answer is a resounding yes, if only for the changing scenery and the chance to visit places like Phu Hin Rong Kla National Park, where rare wildlife and orchid-rich forests await.

Locally, each province has its own specialty: in Khon Kaen, try the famous 'som tam' with salted crab; in Phitsanulok, don't miss the 'khao maew' (black rice porridge), and in Lampang, sample the 'kanom jeen' with local curry.
