The Kalkari Discovery Centre, halfway between the Mt Colah entrance to the Ku-ring-gai Chase National Park and Bobbin Head itself, has displays and videos on Australian fauna and Aboriginal culture. There are kayak and walking tours on which you can see eastern grey kangaroos, swamp wallabies, bush turkeys, native ducks and goannas. A series of information panels gives great information on local tree species.
