Garigal National Park has extensive Aboriginal history, with over 300 Aboriginal sites recorded. These include cave art, rock engravings, shelters, middens and grinding grooves. Many sites are also preserved in Crown land and land managed by the Metropolitan Local Aboriginal Land Council. 

An enormous Aboriginal engraving site, which was the first to be visited by Europeans in 1788. There are over 100 figures representing different scenes.
The main engraving is a large whale, about 11m in length, with an unusually large mouth. Near the whale are two boomerangs and a small figure.
Carvings of two kangaroos, one of which was described by W.D. Campbell as having a spear in its back.
Two echidnas and what has been described as a snake are located on a rock platform close to Mona Vale Road.
Located on the edge of a ledge, with views over Garigal NP, is an Aboriiginal engravnig site with a couple of quite well-defined shields, a kangaroo and a boomerang.
On one of the rock platforms along the Little Moab Track is a school of (four) whales and a deity figure… the engravings are very faint and weathered and hard to make out.
Eight complete or partial hand stencils were recorded in this small shelter in 1981 (some stencils are quite faint, and two are affected by graffiti).
A significant Aboriginal cultural site, the Moon Rock Aboriginal Site was declared an Aboriginal Place in 2016. The site has over 50 engravings, including tools and weapons used and animals caught and eaten in the area.
Located in the middle of an informal walking track between Natural Arch Track and Forestville Park is a wallaby or kangaroo. A few nearby engravings are considered to be fake.
A solitary engraving of a whale with an oblong figure at its snout. Nice views from this rock platform.
A solitary footprint on a rock platform above the Slippery Dip Trail.
