Chiang Dao to Phitsanulok: Ultimate Road Trip Guide

The drive from Chiang Dao to Phitsanulok follows Route 11 south through the heart of northern Thailand, crossing the Mae Yom River at a point that was once a key supply line during the 16th-century Burmese–Siamese wars. Today, this route is part of the Asian Highway AH13, offering a smooth but winding journey of 350 kilometers.

Expect a driving time of roughly five hours without stops, but plan for several breaks to enjoy the landscapes. To see why how to find the best stops and hidden gems between cities matters, read on.

As you leave Chiang Dao, the mountains of the Thanon Thong Chai Range give way to wide valleys. The route passes near the edge of Lamphun's longan orchards, where you can buy fresh fruit from roadside stalls.

Around Lampang, the landscape flattens into rice paddies, and a detour to the Pratu Ma ancient city reveals well-preserved city walls from the Hariphunchai era. Continuing south, the hills of Khao Kho appear, famous for their pine forests and morning mist.

• Natural Landscapes: Doi Kham waterfall (near Wiang Haeng) – accessible during rainy season.
• Hidden Off-Route Spots: Phra At Bat Pu Son temple, perched on a rock outcrop with panoramic views.
• UNESCO World Heritage Sites: The historic city of Sukhothai is a short 30-minute detour from the route.

Fuel stations line the route, with prices around 35 baht per liter for gasoline, slightly higher than in larger cities. Plan your refueling: the longest stretch without a station is between Wiang Haeng and Thoen, about 80 kilometers.

• Road quality is generally excellent, with well-maintained asphalt.
• Toll-free sections throughout.
• Cell phone coverage is patchy, so download offline maps.

Road safety is generally good, but the winding sections near Thoen demand caution. Use designated rest stops every two hours to combat fatigue. For families, the Phu Hin Rong Kla National Park offers educational trails and a safe, kid-friendly environment. For pet owners, many rest areas have shaded parking and walking paths, but leashes are required.

• Family and Child Suitability: Chiang Dao Cave – easy to explore with older children.
• Pet-Friendly Framework: The park at Lampang has a pet-friendly cafe with water bowls.
