Capertee Valley

The Capertee Valley is a large valley in New South Wales, Australia, and (135 km (84 mi) north-west of Sydney. It is longer and about 1 kilometre (0.6 mi) wider than the Grand Canyon of Arizona. Despite this, and being only a two and a half hour drive from Australia's largest city, Sydney (135 km (84 mi) NW), the Capertee Valley is little known, in or outside of Australia, except by bird watchers.

The valley follows the Capertee River as it cuts through the Sydney Basin, a sedimentary basin consisting of Permian and Triassic sedimentary rock west of the Blue Mountains.The valley is classified by BirdLife International as an Important Bird Area because it is the most important breeding site for the endangered Regent Honeyeater. It also supports populations of the Painted Honeyeater, Rockwarbler, Swift Parrot and Diamond Firetail.

In the US published book Fifty Places to Go Birding before You Die, author Chris Santella lists Capertee Valley as one of only two locations in Australia selected in his top 50 world bird watching locations.
