The Lan Hin Pum (knob rock field) was formed by unusual geological weathering processes, creating clusters of rounded rock protuberances.
Lan Hin Taek is a large sandstone plateau divided by deep, naturally occurring crevices that serve as a unique geological landmark.
The park served as the headquarters for the Communist Party of Thailand between 1967 and 1982.
The 'Water Turbine' site shows primitive mechanical tools used by the Communist Party to mill rice during their occupation.
High elevation leads to frequent heavy fog, which plays a crucial role in maintaining the park's lush montane vegetation.
The park is home to a diverse array of wild orchids that bloom predominantly during the rainy season.
Chula Falls offers a multi-tiered cascade accessible via a moderate trekking path through the jungle.
The park's museum displays artifacts left behind after the surrender of the Communist insurgents.
Phu Hin Rong Kla National Park is a mountainous sanctuary situated on the border of Phitsanulok and Loei provinces, reaching elevations up to 1,820 meters above sea level. The park is historically significant as a former stronghold for the Communist Party of Thailand during the 1970s conflict. Visitors can explore the Military Political School and various bunkers scattered throughout the dense forest. The terrain features dramatic sandstone formations, including the Lan Hin Taek (cracked stone field) and Lan Hin Pum (knob-like rock field). The park experiences a significantly cooler climate than the lowlands, making it a popular retreat during the winter months. Birdwatchers frequent the area to spot species native to high-altitude montane forests. The park covers over 300 square kilometers, incorporating diverse ecological zones and waterfalls like the Rom Klao-Paradorn waterfalls. It remains a site of intersection between military history and geological study.

Bring a warm jacket, as temperatures drop significantly at night even during the summer.
Wear sturdy hiking boots with good grip for the uneven sandstone surfaces.
Carry a flashlight if planning to explore the rocky crevices or caves safely.
Attempting to hike to remote waterfalls without informing the park ranger station, as paths can become obscured by vegetation.
Some trekking trails may be temporarily closed during the peak of the rainy season due to safety concerns and slippery terrain.
Maintain silence near historical military bunkers; refrain from picking wild orchids or removing geological specimens.
