There is a lot of activity around Hayle at the moment and not much attention is being given to long-used footpaths. Unfortunately, if a footpath does not appear on Cornwall Council's Definitive Map, it is not considered legitimate.
However, it is possible to register footpaths and have them added to the Definitive Map. This is a somewhat laborious process as users have to fill in a four-page form detailing when and how they have used the footpath. There has to be evidence of use for 20 years without any restriction by the land owner.
