It's my BFF's 30th next month and I want to get her something special. Her and her fiance went to Australia a couple of years ago and loved it so they are returning for their honeymoon in September. I know she wants to climb the bridge so thought i would pay for her to do this. Any recommendations of who to book it through or is there just one company that do it? Also, any recommendations as to a day time or night time climb? Thanks
