The trail starts in Epping in the southwest, crosses Dedham Vale and Constable country to finish at the port of Harwich on the Stour estuary.
It leads through ancient woodlands, open farmland, tree-lined river valleys and leafy green lanes, unveiling historic towns and villages along the way.
The original CPRE signs were dark green, but most of these have now been replaced with Essex County Council plaques depicting two poppies on a white background.
The guidebook illustrates points of interest along the way and includes an accommodation guide for the whole route.
