You begin with an orientation, signing your life away, and taking a breathalyzer test. Next, you change into the climbing suits. Believe it or not, they match the color of the bridge so as not to take away from the bridge itself. I would suggest wearing very light clothing underneath the suit. You are then given the belt that attaches you to the bridge. You are then given time to practice on sample ladders and bridges.
The climb itself is a lot less strenuous than I thought it would be. The only hard part was the straight-up and -down ladders. The bridge itself has such a gradual rise, you barely notice that you are climbing. Also, because of the many photo opportunities along the way, you have plenty of time to catch your breath along the way.
You have headphones on the whole time, and the guide speaks to you through these. On our particular tour, we had a woman who has deaf. The guide was very understanding and allowed time for her husband to sign to her.
The views were spectacular, and I have a great picture of my husband and I with the Sydney Opera House in the background. You get one complimentary group photo with your climb price. The price itself is a bit steep. It was close to $200 per person in Australian dollars, but when will you ever get the chance to climb on a bridge again… unless that is your job.
