A quiet bushland trail to a small automated lighthouse and Aboriginal rock engraving site overlooking the entrance to Middle Harbour, rarely visited by tourists.
The walk to Grotto Point Lighthouse runs through Sydney Harbour National Park bushland near Clontarf on the lower North Shore, one of the least-visited sections of the harbour's extensive walking track network despite being only a short bus ride from the city. The out-and-back track passes native heath and eucalypt forest before reaching the small automated lighthouse, first built in 1911, perched on a rocky point with views across the harbour entrance.
A signposted side track near the lighthouse leads to a set of Aboriginal rock engravings depicting fish and other figures, protected in place and best viewed without touching the sandstone surface. The trail's relative obscurity compared to Manly or Bondi's coastal walks makes it a reliable way to find quiet bushland close to the city, particularly on weekends when the more famous walks are crowded.
