Enter the largest outdoor art gallery on Earth - the Inside Australia exhibit created by world-renowned artist Antony Gormley. Here, stretching across 10 square kilometres, a collection of 51 individually cast black chromium steel sculptures stand against the dramatic backdrop of Lake Ballard's white salt plain. Day tours from Kalgoorlie regularly visit the art installation, or you can drive there in 45 minutes from Menzies, or in one hour and 45 minutes from Kalgoorlie. Each sculpture represents one of the local residents of Menzies. For a fantastic overview, climb the hill and see the sculptures disappearing into the distance, each connected by the footprints of visitors. The Inside Australia exhibit forms part of the self-drive Golden Quest Discovery Trail, which takes in eerie gold rush ghost towns, historical gold mining sites and the former home of US President Herbert Hoover in Gwalia. The best times to visit are early morning or late afternoon, when the sculptures' shadows stretch across the lake. Allow at least two hours, but it will take considerably longer to view all 51 sculptures as they are spaced 500 metres apart. Always walk with a friend and carry water as the heat can be extreme during summer.
