Melbourne is a hub of activity with a thriving arts and food scene, and one of Australia's biggest attractions. On a City Sightseeing Melbourne hop-on hop-off tour, you get a 24- or 48-hour ticket that offers unlimited sightseeing along two routes that take you to the must-see spots such as the Arts Centre, Etihad Stadium and Eureka Tower, which has the highest public vantage point in the Southern Hemisphere. See the sights with 360-degree views on the open-top double-decker bus, and then hop off to explore on your own.
