## History

Between 1968 and 1972, the area was the scene of fighting between Thai communist insurgents and the Royal Thai Armed Forces. Due to the difficult terrain, it was initially impossible to achieve success against the communists and tactics had to be changed. The military were able to convince the Hmong community present around the area to cooperate with the Thai government. This worked out perfectly and the communist insurgents surrendered without further bloodshed.
A survey was set up of Phu Hin Rong Kla forest in the area of Bo Pho subdistrict, Noen Phoem subdistrict and Ban Yaeng subdistrict, Nakhon Thai district, Phitsanulok province and Kok Ssathon subdistrict, Dan Sai district, Loei province in February 1983. Later the Royal Forest Department proposed to include Phu Hin Rong Kla in the system of national parks on March 15, 1983. Phu Hin Rong Kla was declared the 48th national park on July 26, 1984. Since 2002 this national park has been managed by Protected Areas Regional Office 11 (Phitsanulok)
