An exciting, cosmopolitan city, Sydney is famous the world over for its stunning harbour. If you're planning a break in the destination, there is no better way to start than with a Sydney Harbour cruise, which will show you some of the location's most incredible sites.

Once you have booked your Sydney business class flights, you can start planning the finer details of your getaway. Whether you're entirely new to the city or you have been before, you're bound to be drawn to the spectacular harbour.

Perhaps most famous for being home to the iconic Sydney Opera House, the area is a wonderful national park comprising many fascinating islands, as well as the harbour itself.

One of the best ways to admire great views of the area, to visit its intriguing islands and simply to enjoy a relaxing holiday excursion is by taking a Sydney Harbour cruise. These come in many guises, from those that sail around the whole area to trips that just visit an island at a time.

Plus, you'll find there are also voyages on which you can enjoy amazing lunches or dinners – perfect for if you're planning a special occasion.

Indeed, if you opt for a dinner cruise, you can indulge in delicious cuisine as you admire stunning evening views out over the harbour – and, in some cases, there will be live music and dancing to entertain you too.

Generally departing from Circular Quay and Darling Harbour, cruises can allow you to enjoy simply magnificent views out over the harbour – and give you the chance to spot some sights that you might like to explore once you get back out on shore.

For example, you could see the Royal Botanic Gardens, which sit on the edge of the harbour and comprise 30 hectares of beautiful vegetation.

Perhaps some of the national park's biggest attractions are its islands, which you can admire views of from the vessel, or disembark and visit. These often have historical and cultural importance, providing insights into the city's – and Australia's – past.

For example, Cockatoo Island is designated a UNESCO World Heritage site due to its history as an Australian Convict site. Why not take a tour of the isle and learn more about its history on a cruise?

So, if you're itching to discover all the sights of Sydney, consider starting your break with a cruise around the harbour.

To make your journey as enjoyable as your time in the city, look for business and first class flights to Australia.
