Screwpile Jetty ... The Screwpile Jetty provides a lookout for watching whales play in winter, seeing dolphins swimming nearby and parasailers flying over in summer. The Bistro at Granite Island is a fantastic spot to enjoy superb food amongst good company. Over looking the water, the views are breathtaking. Land based fishing is available off the causeway, the breakwater and of course the famous Screwpile Jetty. (Close)
