Yengo is home to a great diversity of wildlife, including around 50 species of mammals such as wombats, wallaroos, koalas and gliding possums, and over 200 species of birds. Watch out for the gang gang, yellow-tailed and glossy black cockatoos gliding between the treetops, or see if you can spot a lyrebird darting across bush tracks. Look closely at the steep rugged cliff faces found in the park as you might catch a glimpse of the endangered brush-tailed rock-wallaby.

Yengo National Park and the surrounding areas have been an important spiritual and cultural place for the Darkinjung and Wonnarua People for thousands of years. No wonder there are over 640 recorded Aboriginal cultural sites in the park and nearby areas. Creation stories recount that Biamie, the ancestral being, stepped off the flat top of Mount Yengo into the sky when he finished his creation. Today, Aboriginal stories and rock engravings connect us with the rich culture of this ancient land and its people.

Yengo offers a range of activities and options for all ages. Unsealed tracks through remote valleys provide opportunities to explore the park on mountain bike or by 4WD. For bushwalkers, there are many options to experience the rugged beauty of the park on foot, with both short walks and overnight walks. In the Big Yango precinct, there are even opportunities for horse riding adventures.

Yengo National Park is one of the eight conservation areas that make up the massive Greater Blue Mountains Area World Heritage Property. Covering one million hectares, it was included in the World Heritage list in December 2000 for its remarkable geographic, botanic and cultural values. There are more than 90 different eucalypt species found here - some 13 per cent of all eucalypt species in the world.
