A 15 minute drive north of Wave Rock is another massive granite rock, known as the Humps, standing proud of the flat surrounding land. There is a trail that can be followed over the rock but near the beginning is a cave that, like "Hippo's Yawn", has been under weathered. Inside is a great place to shelter and in some idle moments the local aborigines had stenciled images of their hands onto the walls and ceilings of the cave.
