Top 10 Things To Do in Sydney. At the top of the list is climbing the Sydney Harbour Bridge. Just can't beat the view! Sydney Opera House, Blue Mountains, and a harbour dinner cruise. Sydney was made for travellers.
Climb Sydney Harbor Bridge - I was in Sydney about two years ago, and while my family climbed the bridge, I was too scared and my sister stayed on safe grounds with me! Hopefully one day I can go back and climb the bridge!
