South Head is at the entrance to Sydney Harbour and is part of Sydney Harbour National Park. Standing atop the sandstone cliffs of South Head gives you a magnificent outlook across the harbour and beyond.
Also found on South Head in the Sydney Harbour National Park is the Gap Bluff Centre, which covers 50 hectares of parkland and has two heritage buildings, the Armoury and Officers' Mess. From the centre you can follow the signs to The Gap, a famous section of cliffs which offer brilliant views of the ocean.
To reach South Head you can take bus 325 (via Nielsen Park) or 324 to Watson's bay from Circular Quay. However, the best way to visit South Head is to travel to Watsons Bay by ferry.
