What are we talking about here? There's a difference between what you can do and what you have a right to do. You can walk across any land you can gain physical access to. But in England and Wales you almost certainly don't have a right to walk across said land. In Scotland you do but you are mistaken if you think England and Wales are like Scotland in this regard (sadly).
