The Nattai area is the traditional territory of the Dharawal and Gundungarra Aboriginal peoples. The Wollondilly and Burragorang valleys historically form a transition zone between the two. The land and waterways, and the plants and animals that live in them, feature in all facets of Aboriginal culture, including recreational, ceremonial, spiritual, and as a main source of food and medicine. They are closely associated with the dreaming stories and cultural learning that are still passed on to this day.

Nattai is a wonderful place to experience a range of environments, from exposed sandstone plateau tops, forests and sheltered gorges. Stroll among eucalyptus trees, pockets of blue-leaved stringybark forest and, on the Nattai River, majestic stands of Nattai Sandstone River peppermint forest. In the northern part of the park, you'll find communities of red bloodwood, Sydney blackbutt, red ironbark, scribbly gum, Sydney peppermint, and smooth-barked apple trees. A variety of remote habitats support up to 9 frog species, 160 bird species, and 19 reptile species. You may also spot wallaroos, emus, swamp wallabies, eastern grey kangaroos, dingos, wombats, echidnas, forest microbats and gliders. Some threatened species you may see are long-nosed potoroos, tiger quolls, powerful owls, and glossy black cockatoos.

For the adventurous hiker, Nattai is a wilderness paradise offering rugged walking experiences rarely found so close to major cities and towns. There are several long hikes that will suit well-equipped nature lovers. Choose between a number of routes, all of them featuring incredible scenery among the sandstone cliffs and woodlands, including Couridjah Corridor walk, Mount Jellore or Starlights trail.
