[3] There are three major power transmission lines running through the park: Rowville-Templestowe Single Circuit Southern (first and second), and Rowville-Ringwood.

[5] The park forms part of the wildlife corridor of Dandenong Creek, and contains a large amount of riparian forest, as well as wetlands and swamps and some areas of indigenous revegetation.

[2] Koomba Park has several man-made water bodies, and is classified in the Urban Floodway Zone since it is prone to inundation.

In 2023, the Koomba Park Boardwalk was closed to public access "for the foreseeable future" due to "ongoing safety concerns".

Koomba Park has a large carpark at the southern end, on a service road off Mountain Highway, which is shared with Wantirna Reserve.

The park is known by locals and the Victoria Police to be a meeting point for drug deals and gay sex, due to its remoteness from residential areas and densely wooded forests, especially at night.

[18] In 2010, a 50-year-old man fell from an elevated boardwalk in Koomba Park whilst cycling, suffering fatal injuries.
