Yengo National Park was an important spiritual and cultural place for the Darkinjung and Wonnarua People for thousands of years, and 640 Aboriginal cultural sites are recorded in the park and nearby areas. Being a largely untracked wilderness area, many of these are difficult to access. It is said that Baiame, the ancestral being, stepped off from Burragurra to the flat top of Mount Yengo and back into the sky when he finished his creation.

Accessible by four-wheel drive (or by walking), this deeply spiritual site is located along the Boree track and includes the spirit footprints of Biame.
The signposted Finchley cultural walk provides access to the Finchley Aboriginal Site, considered one of the best Aboriginal engraving sites in Australia.
