Nan to Saraburi: Scenic Drive with Hidden Gems

The Route 1020 from Nan to Den Chai is a scenic mountain highway carved through the Phi Pan Nam Range. The average grade on this two-lane road is 5%, with hairpin turns that demand moderate driving skill. This route is historically significant as part of the old trade route connecting the Lanna Kingdom to the Chao Phraya River basin.

The full journey spans approximately 450 kilometers, mostly on Route 11, and typically takes 7–8 hours of driving time, excluding breaks. Along the way, you'll traverse three distinct geological zones: the granite peaks of Nan, the limestone karsts of Uttaradit, and the alluvial plains of Saraburi.

Driving offers the flexibility to explore the gap between a northern cultural hub and a central industrial powerhouse. This guide covers the how to find the best stops and hidden gems between cities concept, ensuring you don't just follow the GPS.

The route passes near the Mae Yom National Park in Lampang, offering glimpses of teak forests and the Yom River. For a detour, the Phu Soi Dao National Park in Uttaradit is accessible via Route 1147, featuring a 2,020-meter peak and waterfalls. These areas are pristine, with limited development.

Along the way, local markets such as the Den Chai morning market sell Sonklin rice, a fragrant local variety, and fresh tamarind from central Thailand. In Uttaradit, the Laplae district is famous for its durian orchards, which are sold along the highway in season (June–August).

Saraburi is home to the Wat Phra Phutthabat, a UNESCO World Heritage Tentative List site, renowned for a Buddha's footprint relic. The temple attracts pilgrims year-round, and the surrounding town offers traditional Thai massage shops and snack stalls.

Fuel stations are abundant along Route 11, but in the mountainous portion between Nan and Den Chai, they are sparse—fill up in Nan before departure. Diesel prices in Thailand are centrally regulated, currently averaging 30 THB/liter, so the trip's fuel cost is roughly 600–800 THB for a typical sedan.

The roads are predominantly asphalt with good surface conditions. The 1020 has multiple switchbacks, but the 11 is a divided highway with a 90 km/h speed limit. Toll-free throughout, this route is a budget-friendly option compared to the toll expressways near Bangkok.

Restrooms are available at gas stations every 30–60 km on the main highway. For longer queues, PTT stations often have clean facilities and small convenience stores.

• Route 1020: 2 lanes, no shoulder, watch for livestock.
• Route 11: 4 lanes divided, well-marked exits.
• Peak hours: Avoid weekends during Thai holidays.

The mountainous section has steep inclines; use engine braking to avoid brake fade. In rainy season (June–October), fog can reduce visibility to 50 meters on high passes. Keep headlights on dipped beam and maintain a safe distance.

For families, the Phu Hin Rong Kla National Park (off Route 11) offers a short nature trail suitable for children. Pit stops at major service centers like Wang Thong have playgrounds and food courts serving kid-friendly Thai dishes like khao pad (fried rice). Breastfeeding rooms are scarce, but most modern restrooms have changing tables.

Pet owners should note that only certain rest areas permit pets; the PTT station at Km. 450 near Phitsanulok has a designated pet zone. Carry your pet's vaccination records as some hotels require them. For drivers, rest every two hours—the official guideline—and make use of the 'Rest Area' signs every 40 km on Route 11. It is worth driving Nan to Saraburi mainly to enjoy the changing landscapes, but fatigue management is key.
