Lake Lefroy is a large salt lake in southern Western Australia. It is north of Lake Cowan and near Boulder.[1] Kambalda is on its western edge.
Lake Lefroy is approximately 510 km2 in area and is actually about 55 km from Boulder, but nestles on the edge of Kambalda and Widgiemooltha; it is widely used for land sailing, and is considered by many all over the world to be one of the best places to sail a land yacht due to its size and the texture of its surface. The lake and its surface have been used in the past for Australian land speed record attempts and also hosted the 2007 Pacrim Land Sailing Event in which competitors from all over the world descended on its flat smooth surface. Just recently, in 2008, an English adventurer spent two weeks on the lake with his own designed and built yacht to attempt the world wind powered vehicle record but Mother Nature failed to help out.[2]
