Empire Marina Bobbin Head sits on Cowan Creek within Ku-ring-gai Chase National Park, about 24 kilometres north of the Sydney CBD.

Sheltered on all sides by the park's bushland and wooded hills, it serves as a practical gateway to Broken Bay and the broader network of Cowan Water, Pittwater, Brisbane Water, and the Hawkesbury River.

The marina offers deepwater berths ranging from 8 to 30 metres, along with moorings, full maintenance services, and boat sales. Its wide fairways make it one of the more straightforward berthing options in the Sydney region.

Public parking is available at the wharf precinct and on the opposite side of Cowan Creek, and the site carries an easy disability-access rating.
