There is a path around them that you are not really supposed to venture off but we did couldn't control ourselves i'm afraid. I didn't feel that i was being disrespectful by doing this as on that day we were the only visitors. I can see the point if there was hundreds of people wandering at the same time which could cause damage but I don't believe a couple of folk once in a while can hurt.
I hope it is quiet when you go
