History.
Part of the park originally formed as a the Elouera Bushland Natural Park which was reserved in 1964 and consisted of . Additional lands were acquired and the park was gazetted as Reserve No. 100092 for public recreation and the study and preservation of native flora and fauna in 1987. This gazettal was in response to increasing community concern over the development of bushland areas in the Hornsby Shire. The park then came to be known as Berowra Valley Bushland Park. Further land additions were made to the park, which was gazetted as Berowra Valley Regional Park on 27 March 1998, and was gazetted as a national park in September 2012.
On 27 January 2013 a man was found alive in the park after spending 9 weeks being lost. He survived one of Australia's worst heatwaves during which daytime temperatures reached more than 45 degrees, surviving on water and food he had brought with him.
