In the
United Kingdom, public rights of way are paths on which the public have a legally protected right to pass and re-pass. The law differs in each of the
constituent countries of the kingdom: notably, in
England and Wales rights of way only exist where they are so designated (or are able to be designated if not already); in
Scotland, meanwhile, any route that meets certain conditions is defined as a right of way, and in addition there is a general presumption of access to the countryside. Private rights of way or
easements also exist.
