Our walk details now include three unique words (What3Words) to help you locate the start location. The What3Words smartphone app has divided the entire surface of the Earth into 57 trillion 3m x 3m squares. A unique three-word code for each square is generated by an algorithm in the app within the phone – no external communication is needed to do this. For a short explanation of the tool and its use in an emergency, click on the following link to an article on the Ramblers Head Office website written by the Chair of the Royal Institute of Navigation's Technical Committee. You can download the What3Words app to your mobile from your mobile's app store. The second link below will take you to the wesbite of the company that has developed the application.
