I have to rate this excellent, but let me say, I HATE HEIGHTS. I did it as I bought this experience as a gift for my wife, well I couldn’t leave her to do it alone. Our guide was Charlotte and she was fantastic. These guys are really big on safety. At no time did I feel unsafe, but as I hate heights I was scared on occasions. Climbing the steep ladders up and down wasn’t great particularly with trains rumbling past, but again, I was in no danger. The views are truly stunning especially at sunset. It was very windy, but because of the suits, we were all pretty hot, still. I hope you all give it a go, but don’t look down.
