Dolphin Park is located near Whale Beach between Barrenjoey Road, Whale Beach Road and Dolphin Crescent.

The reserve protects an example of Spotted Gum Forest, which is significant in NSW and it is adjacent to Careel Bay, a significant estuarine wetland habitat, and forms an important habitat and part of a wildlife corridor for faunal movement on the Peninsula

Plants

The Reserve supports a mixture of vegetation communities. The lower section of the Reserve near Pittwater is a transition between of Swamp Mahogany Forest and Swamp Oak Woodland. The southern slope supports Spotted Gum Forest dominated by Spotted Gum (Corymbia maculata),Spotted Gum Low Open-forest is present on the ridgetop with trees 4-5m high.

Animals

Although the provision of grassed areas in Dolphin Park has disturbed fauna habitat, the upper section of the Reserve contains a thick mesic understorey, rock outcrops and tree hollows. The canopy is generally still intact throughout the Reserve, providing mature habitat trees such as Spotted Gums and Swamp Oaks.  The reserve provides suitable habitat for the endangered population of Squirrel Glider, Glossy Black-cockatoo and the Greater Broad-nosed Bat.
