Ku-ring-gai Chase National Park is located just 25km north of Sydney and forms part of the country's National Heritage List. The scenery is stunning, being sited at the point where the Hawkesbury River meets the sea; it also enjoys a rich Aboriginal heritage. It's very popular with picnickers, walkers, swimmers, boating enthusiasts, cyclists and even horse riders. There are numerous picnic and barbecue areas and cafes at Akuna Bay (where there is a marina and boat hire facility) and Bobbin Head (also with a marina and slipway).
There are good opportunities for fishing, both from the shores and aboard boats, and the fish are plentiful. The freshwater pools and sheltered beaches around Ku-ring-gai Chase National Park are also perfect for bathing. There is only one place to camp at Ku-ring-gai, and that's the Basin Campground, which is renowned for its sheltered, sandy beach and inland lagoon. It can only be accessed by boat or ferry. There are some privately-run accommodation options just outside the park as well.
There are various access points to the park and all are well signposted from the Pacific Highway. Bobbin Head and Appletree Bay are popular starting points for exploring the park.
