Sydney Harbour National Park protects large swathes of bushland around the harbour shoreline, plus several harbour islands . In among the greenery you’ll find walking tracks, scenic lookouts, Aboriginal carvings, beaches and a handful of historic sites. The park incorporates South Head and Nielsen Park on the south side of the harbour, but most of the park is on the North Shore – including Bradleys Head , Middle Head , Dobroyd Head and North Head .
