Great Mackerel Beach is a picturesque suburb located about 43 kilometers north of Sydney's central business district. It is nestled within Ku-ring-gai Chase National Park, offering stunning views of Pittwater. The beach features a long, wide sandy shoreline with rocky portions, making it a serene getaway from city life. The resident population is small, with many properties serving as weekend retreats for Sydneysiders. Access is primarily by ferry or private boat, adding to its secluded charm.
The area was originally settled in 1823 as a dairy farm and underwent significant development after 1920, transforming it into a popular spot for beachside cottages and upscale homes. Visitors can enjoy activities like snorkeling, swimming, and fishing amidst the beautiful natural surroundings.
The sand on the beach is soft and golden, formed from sandstone flowing down the Hawkesbury River. This idyllic setting offers a peaceful retreat with opportunities to explore the surrounding national park, which includes ancient Aboriginal sites and diverse wildlife.
