The Long Distance Walkers Association Register of National Trails (NT Register) provides an incentive to venture out on some of the best walking trails the United Kingdom has to offer and is open to members and non-members.

For the purposes of the NT Register, National Trails are defined as the National Trails of England and Wales that are way-marked with the "Acorn" logo, plus the official Long Distance Paths of Scotland that carry the "White Thistle" way-marking.
