CROW stands for the Countryside and Rights of Way Act 2000. This UK legislation grants the public the “right to roam” over certain areas of land, such as mountains, moorlands, heaths, downs, and registered common land, while also setting out restrictions and responsibilities for landowners and the public.
It applies mainly to England and Wales and allows people to access designated open land without needing the landowner’s permission, though some activities (e.g., camping, cycling, and horse riding) may still be restricted.
