Great coast to coast route across mid Cornwall mainly off road trails and occasional quiet roads. Coffee stops, pub stops, great scenery, mining history and coastal views. There is nothing to dislike about this route.

Bit of a bouncy ride between Portreath & Bridge but the Tramroad is a great route to follow.
