In reply to Dan Mckinlay:
Hi Dan. If you visit the Natural England Open Access site there is a search facility that allows you to select any area and date you wish. A series of off files appear that give you dates and restrictions. There doesn't seem to be any current restrictions for Ash Head other than the general one relating to dogs.
However, I talked to a guy the other day and he said it wasn't impossible that new ones would appear .....
