A report was submitted on the State Reserved Forest Supervision by the Thap Sakae Forestry Department stating that this area has two beautiful waterfalls and should be established as a Forest Park. The Phetchaburi Forest Department sent personnel from the Forest Park Ranger Station Po Cho No. 3 (Thap Sakae) to conduct a detailed investigation.

        It discovered Kha-on Waterfall (Tap Mon) and Huai Hin Dat Waterfall, and is suitable to become a forest park in order to preserve this beautiful forest and watershed. Mr. Thammarong Prakobboon, Director of the National Park Division proposed to the Royal Forest Department that it should establish a National Park. 

         The National Park Division has a letter dated June 9th, 1987, Ko So No. 0713/1673, addressed to Mr.Sin Maliwan, Forestry Officer Level 4, at Namtok Huai Yang Forest Park asking him to conduct a preliminary survey  around the area containing the two waterfalls. The survey results, according to Ko So No. 0713 (Ho Yo)/161 of Namtok Huai Yang Forest Park, dated September 14th, 1987, suggested that the forests and waterfalls be merged into the Namtok Huai Yang Forest Park to protect natural resources.
Later, the National Park Division issued a letter numbered Ko So 0713/2613 on July 8th, 1988, requesting Namtok Huai Yang Forest Park to include Wanakon Beach area into the National Park. According to the suggestion of Mr. Kasem Rattaanachai, Assistant of Petchburi Forestry Office, and according to the survey, the results of the survey, according to the forest park book Ko So 0713 (Ho Yo)/148 dated November 29th, 1988, Wang Duan Forest and Huai Yang Forest (Wanakon Beach), should be included in the entire area, and established as a part of the National Park. 

         An inspection of the Phetchaburi Forestry Office by Mr. Yukti Sarikaputi, Deputy Permanent Secretary for Agriculture and Cooperatives, acting for the Director-General of the Royal Forest Department between December 31st, 1988 and January 2nd, 1989, ordered the area around Wanakon Beach to become a National Park. At the meeting of the directors of the Royal forestry department  on January 5th, 1989, Huai Yang Forest Area and Huai Yang Forest Plantationwere considered to be included, which is the area adjacent to Wanakon Beach.

         The National Park Division began the process of merging Kha On Waterfall Forest area, Huai Hin Dat Waterfall, and Namtok Huai Yang Forest Park to Thap Sakae Forest in Thongchai Sub-district in Bang Saphan District, Ang Thong Sub-district in Thap Sakae District in Prachuap Khiri Khan Province, and Wang Duan Forest, Huai Yang Forest in Huai Sai and Huai Yang Sub-district, Mueang and Thap Sakae District in Prachuap Khiri Khan Province, It has a total area of approximately 124,300 rai s or 199 square kilometers (including 15.36 square kilometers of water area), and became a National Park under the National Park Act 1961. The National Park Division are in Namtok Huai Yang National Park area, which includes Kha on Waterfall, Huai Hin Dat Waterfall, and Namtok Huai Yang Forest Park, which are connected, while Wang Duan Forest and Huai Yang Forest ( Wanakon Beach) are not linked.
