Definitely! There have to be restrictions on where we can go otherwise we end up destroying that which we value.

In my own lifetime I’ve seen access to Silbury, Stonehenge, The Hall of Dreams, and the Moss Garden curtailed, and all curtailed for the same reason – ie that visitor numbers were threating the very fabric of the site. No doubt the trend will continue and we'll see more restrictions come into place. Meanwhile, we should respect site owners' requests, whether they're farmers, English Heritage, the National Trust or the MOD.

If we're concerned with the long-term conservation of places, and the sign says stay off, then stay off. Simples!
