On the 29th of November 2000 the World Heritage Committee inscribed the greater Blue Mountains area on the World Heritage List. Kooyong is positioned directly alongside the Blue Mountains National Park, which forms part of this World Heritage Listing. A short walk along the bush track, which leads into the National Park, opens up views of the Jamison Valley and Mt. Solitary, with distant views towards Mt. Gibraltar and the Southern Highlands. A further short walk along the bush track will take you into the walking trails of the Lyre Bird Dell and pool of Siloam circuit.

Aboriginal habitation in this area has been confirmed over 8,000 years ago, and a large overhanging rock in Lyre Bird Dell was a shelter used by local Aboriginals. The Dell and the Pool of Siloam provide a cool moist atmosphere with the walk through the small canyon, featuring rainforest and heathlands.

Return to Kooyong and enjoy the contrast of the natural landscape, gums and eucalypts of the National Park, with the garden and European deciduous trees of Kooyong.
