Just a short distance away, you can find the Museum of Contemporary Art (MCA) and The Rocks, an artsy neighborhood that is well-known for its thriving restaurant and bar scene.
No trip to Sydney would be complete with a visit to its famous beaches. Be sure to spend a day at Coogee and Bondi Beaches, while also visiting the historic lighthouse of Watsons Bay and UNESCO listed Cockatoo Island.
