A themed walk is a type of informal learning and often is defined by a walk along which there are information boards or other identifying codes (e.g. QR codes) covering a specific topic or theme such as history,[1] geology or forestry. An academic discipline or school subject can define a theme. A walk can consist of one or more themes. Whilst themed walks are often designed to encourage walking, educational paths and nature trail tend to be aimed more at educating or training.
