The Dandenong Ranges, originally known as Corhanwarrabul, are a set of low mountain ranges, rising to 633 metres at Mount Dandenong, approximately 35 km east of Melbourne, Victoria, Australia. The ranges consists mostly of rolling hills, steeply weathered valleys and gullies covered in thick temperate rainforest, predominantly consisting of tall Mountain Ash trees and dense ferny undergrowth.
After European settlement in the region, the range was used as a main source of timber for Melbourne. The ranges were popular with day-trippers from the 1870s onwards. Much of the Dandenongs were protected by parklands as early as 1882 and by 1987 these parklands were amalgamated to form the Dandenong Ranges National Park, which was added to again in 1997.
The range experiences light to moderate snow falls a few times most years, frequently between late winter and late spring.
