Phu Hin Rong Kla is a distinctive national park with a unique mixture of scenic attractions and historical sites. It was once the stage of armed conflicts between two extreme political ideologies.
Because Phu Hin Rong Kla was the strategic headquarters of the Communist Party of Thailand (CPT) during 1967 to 1982, the area was declared as a red area by the Thai government. For nearly two decades, the site had become a strategic battlefield between the Royal Thai Army and the CPT. Phu Hin Rong Kla was the perfect location for the CPT to fight the military. Its remote, closed mountainous area was superb for an elusive defense. It was not until 1982 that the conflict was overcome when the government granted amnesty to all the students who had joined the CPT. In 1984, Phu Hin Rong Kla was declared a National Park.
