Climb the Deliverance Track up the magnificent 162-metre-high Castle Rock, named by explorer Captain Cook in 1770.
To find the track, start at the carpark, walk through the pines above the lagoon and follow the reserve boundary to the base of Castle Rock. Or start from the lagoon beach. As you're walking, keep an eye out for seabirds - terns, gulls, black shags and herons all make their home here. You might also spot the incredibly rare Brachyglottic compacta - a daisy that only grows on the crumbly limestone of the reef and Castle Rock.
After that climb, a stroll up to the lighthouse will be a piece of cake!
