The Act implements the so-called "right to roam" (also known as jus spatiandi) long sought by the Ramblers' Association and its predecessors, on certain upland and uncultivated areas of England and Wales.

The act sets a deadline of 2031 to log all public footpaths, bridleways and rights of way, with view to adding them to an official map.

The three main changes are: the maximum penalty is now a term of imprisonment instead of a fine; the Secretary of State can designate "wildlife inspectors" who have a range of powers under the Act; offences of disturbing certain birds and animals are extended to cover reckless as well as intentional acts.

The act gave power to create local access forums (commonly referred to as 'LAFs'), comprising a balance of user, landowner and other interests, to give advice on development of access land and of the path network; the policy of footpath improvement would be set out in a Rights of Way Improvement Plan (RoWIP).

A more extensive Land Reform (Scotland) Act 2003 was enacted by the Scottish Parliament which formalised the Scottish tradition of unhindered access to open countryside, provided that care is taken not to cause damage or interfere with activities including farming and game stalking.
