The 620-hectare (1,500-acre) national park consists of two sections; the northern section consists of approximately 480 hectares (1,200 acres) and covers a substantial area of the peninsula between The Entrance and Norah Head as well as Terilbah and Pelican Islands within Tuggerah Lake.

[2] The park is also noted for containing the last significant coastal (littoral) rainforest on the Central Coast.

It was found by Governor of Tasmania, Colonel David Collins, who had arrived on the First Fleet, during the search for an escaped convict, Mary Morgan, who was said to be living with the Aborigines to the North of the Hawkesbury River.
