Dandenong Ranges, popular as The Dandenongs, is a low mountain range with the highest peak of 633 meters. Situated almost 35 km from the east of Melbourne in Victoria, the Dandenong range consists of rolling hills, steep eroded valleys, and gullies coated with temperate rainforests and protected parklands dominated by mountain ash trees and dense undergrowth of ferns. Generally, two names refer to the Dandenong ranges; Corhanwarrabul and Dandenong; both these names are derived from the Woiwurrung language- the native language of the Wurundjeri tribe. According to the 2016 census, around 135,000 people permanently reside here, whereas hundreds of tourists visit here for vacations.

The ranges stretch for approximately 2500 square kilometers from the eastern periphery of metropolitan Melbourne, Victoria, and the catchment basin of the Thompson River. The Dandenong range is the realm of an extinct volcano that was last active 373 million years ago. The entire area is covered with deep streams, sheltered gullies, and mountain ash. Several water bodies originate from the Dandenong range; the prominent ones are Cardinia Creek, Clematis Creek, Dandenong Creek, Eumemmerring Creek, Emerald Creek, Ferny Creek, Olinda Creek, Sassafras Creek, and Sherbrooke Creek. Waterfalls are tourist attractions; the important ones are Olinda Falls, Sherbrooke Falls, and Griffith Falls.

Dandenong ranges are easily accessible by roads, railways, and airways. The major roads in the region are the Ridge Road and the Mt Dandenong Tourist Road. The nearest airport is Tullamarine, Melbourne, which is situated 63 kilometers away from the region. Geelong is another airport in Avalon, 99 km away from the state. Buses, managed by Ventura, operate in the city, and the major bus routes are Croydon to Upper Ferntree Gully and Belgrave to Mount Dandenong.
