The Olinda section of Dandenong Ranges National Park, covering 790 hectares between Olinda, Kalorama and the catchment of Silvan Reservoir, once formed part of the Dandenong State Forest Reserve. One of the newer sectiones of the National Park, Olinda boasts relatively undisturbed native habitat.

Three picnic areas are located in the forest. Valley Picnic Ground to the south, Eagle Nest Picnic Ground to the east, and Olinda Falls Picnic Ground to the west.
