Gibraltar Rock, Royal National Park, is a sandstone overhang found near the northern end of Lady Carrington Drive. The old road passes under the rocks and is home to a small section of sandstone cobblestone. At this point, the old road offers great views of the Hacking River and across to Wattle Forest picnic area. These and many other sandstone formations, together with the history, make this old road quite interesting to explore. There is a picnic table under the overhang.
