The Fort is a former Australian Navy Battery built in 1942. The fortified concrete command post was also a observation post, a munitions bunker and two gun emplacements overlooking Cleveland Bay.
The remains are in good condition and are worth the walk/ climb to experience the wonder, and, whilst walking keep an eye out for a Koala or two.
Radical Bay, as the name suggests, affecting the fundamental nature of something, was once a fantastic resort catering to backpackers. It is still a great place for a swim. Radical is accessible by a short rough road, and you don't have to go all the way to swim.
