Sydney Opera House
It's easy to enjoy the Sydney Opera House without even stepping foot inside. The sinuous, shell-topped building, by Dane Jørn Utzon, is a modern marvel, covered with sparkling white tiles that catch the sun. Wander around it, then take up residence at its alfresco Opera Bar to ogle it some more, cool drink in hand. Diners and barflies at in-house Bennelong restaurant get to experience the architecture from within one of the shells, with gorgeous harbor views. You can also attend an opera (naturally) at the house, which also hosts theater, talks, comedy, dance, music, and even pop gigs. To learn more about its design and inner workings, take one of the various tours, which guide you inside and backstage or can be combined with a gourmet three-tier tasting plate from the Opera Kitchen. Sydney's ultimate icon looks particularly fetching during New Year's Eve fireworks and when illuminated during May-June's Vivid Sydney light festival. You can also bag great snaps from the ferry to Manly, Rose Bay, or Watsons Bay.
