This is the Guide to the route written by myself in 2007 so it is little out of date now:
There now follows three videos of the route largely shot from drones. These were created by Tim Shepherd. They do not concentrate on sites connected with Kenelm and the third video seems to take a rather different route, missing out, for instances, St Kenelm’s Well and Sudeley castle.
