Walking on access land gives you the chance to enjoy vast areas of England's outdoors without the need to stick to paths. Commonly known as the 'right to roam' this right covers some of England's most wild and dramatic landscapes, heaths, moors, down and areas of registered common land. The Open Access symbol is used to mark the boundaries of land available for area-wide access.
