Stretch your legs on the heritage-listed Busselton Jetty as it stretches into the turquoise waters of Geographe Bay. This 19th-century landmark is the longest timber jetty in the southern hemisphere, running a mile (1.8km) out to sea.

Walk it in 25 minutes or hop on the jetty train. A day pass covers walking, fishing, diving or swimming, while an extra fee gets you into the Underwater Observatory, 26 feet (8m) below the surface. Scuba divers can also explore an underwater sculpture trail featuring 13 works by WA artists.
