One of the best tours in Sydney is the one that takes you right to the top of the city’s iconic Harbour Bridge. Since 1998, thousands of tourists have made the climb over the 134 meter high bridge, enjoying spectacular views over the city, the harbour and of course, the famous Opera House. You’ll definitely need a head for heights to take the bridge climb, although it is perfectly safe; participants are roped together and are led up the bridge’s walkway by a qualified and professional guide. Several different climbs are offered, varying in duration, although one of the most popular options is the Twilight Climb, which takes place during July and August and includes live music before you start the walk. The bridge climb doesn’t come cheap, but it’s on the bucket list of many travelers, and it’s an unforgettable way to see Sydney.
