A member of The Ramblers’ Association (now known simply as The Ramblers) and reporter Sally Jones follow a route on the map of Sundry Ancient Trackways on Dartmoor starting near Gidleigh Parish Church in West Devon on the Mariners’ Way. Trackways or green ways may date to prehistoric times and started as paths formed by people or animals. In bog areas impressions or fossilised imprints attest to the pathways having been in use for thousands of years.
