Our signature 1 hour flight, encompassing the City of Kalgoorlie-Boulder, the Super-Pit, and Nickel Smelter continues to the magnificent Lake Lefroy, a huge Salt Lakebed south of Kalgoorlie. Standing out from the countryside with its stark expanse, free from all vegetation, and popular with land yachting, this Salt Lake is unique in that it has several open cut mining activities operating as well.
