Garigal National Park does not exist in a singular block, but rather covers various areas, including Bantry Bay, Middle Harbour, and in the suburbs of East Lindfield, East Killara and St Ives, where Garigal National Park meets Ku-ring-gai Chase National Park. With this broad geographical span, it will come as no surprise to learn that at 22 square kilometers, Garigal National Park is the biggest National Park within Sydney's boundaries.
The park is located approximately 20 kilometers north of Sydney's CBD. By car, it is possible to follow the fairly direct route from Pitt Street in the central business district to the popular Roseville Bridge picnic spot within Garigal National Park will take approximately 20 minutes.
According to the New South Wales Department of Environment, Climate Change and Water, Garigal National Park boasts "an impressive expanse of bush and sandstone country close to the heart of Sydney, with great water and bush views, waterfalls, historic heritage and scenery."
Although there are various geographical features that it is possible to enjoy in Garigal National Park, Davidson Park is popular for a range of activities, including picnics, paddling, and fishing. It should be noted, however, the Picnic Area gates are closed between the hours of 6:30pm to 6am and 8pm to 6am during daylight savings.
