You can do a "Story Bridge Climb" which means donning a blue and grey jumpsuit (so that you blend in with the bridge and the sky) and climbing the steps to the summit and checking out the river 80 metres below. I went on the climb a few years ago and loved it but I found it frustrating not being able to take pictures. Anyway, the organisers of the climb have introduced a Photographic Climb where you can bring your own camera and snap away to your heart's content. It's limited to just the camera - no bag, extra lenses, tripod or anything else.... but it looks like you get some great shots from up there. That is on my list for 2012.
