Cruise or fish the expansive, wildlife-rich waters of Lake Argyle, near Kununurra, the biggest man-made lake in the southern hemisphere. Created by the Ord River Dam, it's classified as an inland sea and at its peak in the green season Lake Argyle holds a staggering 32 million cubic metres of water. That's more than 20 times the size of Sydney Harbour.

You can take the leisurely 40-minute drive from Kununurra to Lake Argyle's shores, but the best way to appreciate its immensity is to hop on a scenic flight - you can even go by float plane and land on the lake!

A wildlife cruise of the lake's shoreline and islands will give you close encounters with an incredible variety of native fauna, from freshwater crocodiles, fish and wallabies (looks like a small kangaroo) to more than 240 species of birds - almost one-third of Australia's total known species.

For a long, lazy lunch and a little wildlife spotting, head for the picnic area at the base of the dam wall. Or, if you're feeling more energetic, hit the network of bushwalking trails and enjoy the scenery and tranquillity of Lake Argyle at your own pace.
