I'm afraid of heights and was really nervous about doing this but the tour guides made me feel comfortable and safe the whole time. Guides run the course in the morning to make sure everything is good before opening, they teach you what to do before starting, and you are always clipped to something at any given time. The tour was a lot of fun and the guides Jim and Ledy were encouraging and informative. We bought the pictures that were taken during the tour, it was about $17 for the two of us, which I thought was good since I really wouldn't have wanted to take a camera or my phone to try and take my own pictures.
