A little pricey (offsetting lots of insurance cost), but a great experience! Fletcher, our guide, led a group of 7 (including my wife and me) across the bridge walk, with numerous stops to explain the landscape, the bridge, other area activities, etc., and also to allow for photo opps. We got lots of beautiful pics, and had a great time. The shuttle back to the office / gift shop had cold water for us, which was very welcome! There are slight vibrations from traffic crossing overhead, but the catwalk is very safe and sturdy, and the harness / trolley system is like belt and suspenders for anyone a little squeamish. We had two close sightings of the same peregrine falcon! Highly recommended!
