Lake Argyle is one of Australia’s biggest inland waterways and is the largest permanent reservoir of fresh water in Australia. Peppered with islands in the middle of the lake and edged by ranges, it’s like an inland sea in the desert. Only experienced kayakers should take to the open waters of Lake Argyle, as its vast size allows for winds that can generate waves, and there are long crossings to the islands. But if you are in a position to kayak here, the drinkable water – as well as prolific fishing opportunities – mean you could kayak for weeks around the shores and islands. There are good campsites on Bullanyin and Lagoon islands, but only one launch point into Lake Argyle at the boat ramp, which is well signposted.
