Uttaradit to Phitsanulok: Scenic Stops & Drive Guide

Unlike most of Thailand's rainy central plains, the Route 117 corridor between Uttaradit and Phitsanulok occupies a distinct rain shadow, receiving only about 1,100 mm annually compared to 1,600 mm in nearby Nan. This drier climate means consistent visibility for the AH13 (Asian Highway 13) concurrency that dominates the 120 km route, a fact that shapes both driving comfort and crop cycles you'll see in the fields.

Infrastructure safety is high: the entire length has streetlights at intersections, and the Royal Thai Police operate spot-check points near km 45 (Wang Thong) and km 90 (Ban Na), especially during festive periods. The road shoulders are wide (2.5 m), suitable for emergency stops, but pedestrians and motorcycles are common, so maintain a 3-second following distance.

Culinary infrastructure is well-distributed: every 10-15 km you'll find a noodle shop or coffee stand, but the best stop is at the Tha Sao rest area (km 25), known for its boat noodles and fresh coconut ice cream, a hit with kids. For pets, the family-friendly Thung Salaeng Luang National Park (near Phitsanulok) permits dogs on leash, and several roadside truck stops offer shaded pet-relief spots—a rarity in Thailand.

Fatigue management is crucial: the straight roads induce drowsiness, so plan a break at the Forest Department rest area at km 60, which has picnic tables and a canopy of rain trees. Hidden off-route spots include the Phra Ruang Hot Spring (turn off at km 55, 8 km west), a natural 40°C pool that locals swear by for muscle recovery, and the rarely visited Ban Thung Yai viewpoint (km 70), offering panoramic rice terraces at dawn.

How long to drive Uttaradit to Phitsanulok is a straightforward 2 hours if you maintain the 90 km/h average speed on the mostly straight, well-marked single carriageway. The entire route is public highway, with no tolls, but note that large trucks frequent the section between Ban Kloi and Wang Thong, so plan overtakes carefully.

• Fuel: PTT station at km 32 (Wang Thong) and a Shell at km 78 (Ban Na) both open 24/7; diesel prices here typically average 32 THB/liter, similar to urban rates.
• Road quality: The asphalt is in excellent condition as of 2025, with fresh markings after the 2023 resurfacing project; no construction zones were active at press time.
• Truck stops: Two dedicated rest areas offer weigh stations and food courts, useful for timing your drive to avoid midday heat.

For those wondering is it worth driving Uttaradit to Phitsanulok, the answer lies in the flexibility to detour west to the Khao Kho mountains or east to the Nan River's tributaries, neither accessible by train. The route's economic backbone is rice and sugarcane, and you'll see harvesters active from November to February, a local commerce rhythm that dictates slower tractor traffic on weekends.

Natural attractions cluster near Phitsanulok: Phu Hin Rong Kla National Park (entry 200 THB) offers surreal rock formations and a year-round cool climate, while the Wang Thong waterfalls—Kaeng Song and Nang Phaya—provide swimming spots after monsoon rains. The park's geology is a Permian limestone karst, distinct from the granite of the north, creating cliff-side viewpoints that are family-friendly with railings.

For cultural depth, the UNESCO World Heritage Site of Si Satchanalai Historical Park (actually in Sukhothai province, but a 1-hour detour from Uttaradit) is a must-see; its ruined temples are quieter than Sukhothai's main zone. Closer to Phitsanulok, Wat Phra Si Rattana Mahathat houses the revered Phra Buddha Chinnarat, a 14th-century bronze masterpiece—admission is free for Thais, 50 THB for foreigners.

Local commerce thrives in the roadside markets: Wang Thong's Saturday morning market sells fresh Khao Tom Mat (banana-leaf rice dumplings) and handwoven cotton. For a quieter experience, stop at Ban Na's community craft center, where villagers produce the area's signature indigo-dyed textiles, a lineage dating back to the 19th century.
