Bouddi National Park is a small park lying on the  NSW Central Coast about 60km north of Sydney, on the north side of the mouth of the Hawkesbury River and Broken Bay. It protects an area of coastal heath and moors, as well as a number of delightful beaches, and like most of the other parks in the Greater Sydney Region, it is largely sandstone. Numerous short walks are accessible from the park boundaries to the various beaches of Maitland Bay, Putty Beach, Little Beach and Tallow Beach. Longer walks often involve some road walking or a car shuffle, but good loop walks to Maitland Bay are accessible via Putty Beach or Little Beach.
