    A brief introduction to Sydney

    A modern metropolis filled with natural beauty, Sydney is home to world class beaches, trendy restaurants, intriguing galleries, and lush parks.

    We recommend starting your trip with a visit to the city center, where you can marvel at and take photographs of two iconic landmarks - the Sydney Harbour Bridge and Opera House, which overlook the glittering Circular Quay and Botanical Gardens.

    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.

    Some of the best natural sights in New South Wales can be found in the areas surrounding Sydney, which are best experienced on a day trip. Consider renting a car to visit the UNESCO World Heritage Blue Mountains, and Ku-ring-gai Chase and Royal National Parks.
