This national park contains the four largest areas of remaining forest in the Dandenongs. The Ferntree Gully Area has several short walks, including the popular 1000 Steps up to One Tree Hill Picnic Ground, two hours return, part of the Kokoda Memorial Track, which commemorates Australian WWII servicemen who served in New Guinea. Bring sturdy shoes as its steps get slippery.

Sherbrooke Forest, just north of Belgrave, has a towering cover of mountain ash trees and several walking trails. Grants Picnic Ground, at Kallista, attracts flocks of sulphur-crested cockatoos.
