Darwin Harbour is twice the size of Sydney’s and there’s nothing quite like the views of the city and surrounds from on the water. A range of cruises and craft are available, from sailing vessels to fishing boats and speedy catamarans. Spend a few hours or the entire day. For something really special, Sail Darwin offers Champagne sunset cruises on its 50-foot catamaran, Sundancer. Look back and gaze at the lights of the city; if you’re lucky, you’ll spot some dolphins, too.
