Phu Hin Rong Kla National Park Travel Guide: Nature, History and Cool Mountain Air

If you're looking for a trip that combines cool weather, endless mountain views and history you can actually walk through, Phu Hin Rong Kla National Park travel is hard to beat. Set high in the mountains where three provinces meet, the park was once a key stronghold in Thailand's modern political history. Today it's a favorite with nature lovers, campers and photographers.
This guide covers everything you need: must-see spots, the best time to visit, how to get there from Bangkok, and where to stay in the city before and after your trip.
Getting to Know Phu Hin Rong Kla National Park
Location and Landscape
Phu Hin Rong Kla National Park lies in Nakhon Thai District, Phitsanulok Province, extending into Loei and Phetchabun. It covers roughly 300 square kilometers of rugged highland, mostly between 1,000 and 1,800 meters above sea level. The altitude keeps temperatures pleasant almost all year, and winter nights can get very cold.
The name "Phu Hin Rong Kla" refers to the long grooves and ridges in the mountain's rock, still clearly visible across the park's rock fields.
A History Worth Knowing
From 1968 to 1982, this area served as a base of the Communist Party of Thailand. After the conflict ended, it was declared a national park in 1984. The preserved buildings, school, hospital and hideouts make a visit here more than a nature trip — it's a chance to learn Thai history where it happened.
Must-See Attractions in Phu Hin Rong Kla National Park
Lan Hin Pum (Knob Rock Field)
A wide rock plateau covered in rounded stone knobs, ending at a cliff edge with layered mountain views. It's one of the best spots for sunsets and sea-of-mist mornings, and was once used as a shelter by insurgents.
Lan Hin Taek (Cracked Rock Field)
A huge rock field split by deep natural cracks, some wide enough to walk into. These crevices were once used as air-raid shelters. Today they make for striking photos and a clear look at the area's geology.
Pha Chu Thong (Flag-Raising Cliff)
The park's signature cliff, where a flag was once raised to mark victories. Now it's a beautiful viewpoint, especially at sunrise. The trail is easy and suitable for all ages.
Political and Military School and the Water Wheel
A cluster of bamboo buildings hidden under tall trees, once used for political and military training. Nearby, a water-powered wheel used for pounding rice shows the self-sufficient way of life of the time. You can also visit the former hospital and headquarters hidden in the forest.
Man Daeng Waterfall
A multi-tiered waterfall cascading through evergreen forest, at its best from the rainy season into early winter. The shady trail is ideal for a short jungle hike.
Phu Lom Lo and the Wild Himalayan Cherry Blossoms
Phu Lom Lo, on the Loei side and managed by the park, turns pink every year from late January to February when the wild Himalayan cherry trees bloom — earning it the nickname "Thailand's sakura." Access is usually by designated local vehicles, so check schedules and opening days before you go.
Best Time to Visit Phu Hin Rong Kla
- November–February: Cool season with crisp air, clear skies and a chance of mist — ideal for camping.
- Late January–February: Cherry blossom season at Phu Lom Lo.
- June–October: Rainy season with lush forest and full waterfalls, but roads can be slippery and foggy, so drive carefully.
How to Get to Phu Hin Rong Kla National Park from Bangkok

Drive from Bangkok to Phitsanulok, then take Highway 12 (Phitsanulok–Lom Sak) and turn off toward the park. The total distance is about 500 km, roughly 6–7 hours. The mountain section has steep grades and continuous curves, so make sure your car is in good condition.
By Bus, Plane or Train
- Bus: Take a bus from Mo Chit 2 (Northern Bus Terminal) to Phitsanulok, then a local vehicle or rental car to the park.
- Plane: Fly from Don Mueang Airport to Phitsanulok in about one hour, then rent a car.
