At the northern end of Camp Cove, the South Head Heritage Trail kicks off, leading into a section of Sydney Harbour National Park distinguished by harbour views and crashing surf. It passes old fortifications and a path heading down to Lady Bay nude beach, before continuing on to the candy-striped Hornby Lighthouse and the sandstone Lightkeepers’ Cottages (1858). Between April and November, look out to sea to where the whale-watching boats have congregated and you'll often see cetaceans.
