On 12 January 1970 the National Park Board took a decision to designate a national park. On 3 May 1972 the Revolutionary Council announced: determination of the Nam Nao forest area in Mueang Phetchabun district, Lom Sak district, Nam Nao district, Phetchabun province and Khon San district, Chaiyaphum province to be a national park.

The boundaries of the national park include also the area of Pak Chong Subdistrict and Tha Ibun Subdistrict of Lom Sak District, but they are not mentioned in the publication in the Government Gazette.
