Naree Budjong Djara National Park is Straddie's heartland, home to the glittering Blue Lake. To access the park and the lake, head about 8km east of Dunwich, then drive down the 2.6km (40-minute) bush track. Keep an eye out for forest birds, skittish lizards and swamp wallabies along the way. There’s a wooden viewing platform at the lake, which is encircled by a forest of paperbarks, eucalyptuses and banksias. You can cool off in the water, if you don’t mind the spooky unseen depths.
