Wear sturdy walking shoes as the garden features steep slopes and uneven natural paths.
Bring a rain jacket, as weather in the Dandenong Ranges can change rapidly compared to Melbourne city.
Use the shuttle service if you have mobility issues, as the main garden areas involve significant inclines.
Do not attempt to walk the entire perimeter if you have limited time, as the garden is significantly larger and hillier than it appears on maps.
