My husband and I climbed the Harbour Bridge for a 1 year anniversary of dating and it was great! If you want to do it, I would definitely recommend the 'twilight' time slot - because you climb the bridge in the daylight and coming back down the other side, you get to see the city lit up as day turns to night!
Ooo tough question, Finy! :) I was born and raised in Saudi Arabia, then moved to India for 2 years to complete high school, and have been here in Australia for 4 years now! I don't know where I'll end up next, but I know it'll get added to my list of hometowns!
I've climbed all three bridge climbs, Brisbane's storey bridge, Auckland and Sydney. Sydney is the best by far. It's not that strenuous, there is a lot of stopping for photos etc. and you feel safe because you're hooked to a cable all the way. Highly recommend it, especially at twilight.
Although I've seen groups climbing on the bridge when I've visited Sydney, I've never tried it myself. From what I've heard, it's outrageously expensive, though, so I don't think I'd be able to afford it. I think I might also find it a bit scary. So, no, I probably won't.
No, I haven't, & very doubtful I would! Being 'cable-attached' about 1000' from the Harbour's water surface, would give me the 'heebie-jeebies'! I'd be one of those people who 'freeze' & can't move! Useless to myself & all others there!
Even though I live in Sydney, NSW, Iíve never climbed the SHB. Iím also terrified of heights! And the thought of spending all that money on a climb, when I could spend it on another Swatch watch, or some yummy dark chocolate!
