Hi....
I have done this very off-road route in the past....and had a blast.....the ride back up to Princetown from Burrator is a bit of a grind-but the scenery is spectacular. I have also attempted an 'off-road' North to South traverse of the Moor (with an overnight wild camp) which was a bit of an adventure. Kind of made that one up as I went 'though!
Too old for all that bouncy-bouncy now!!
Best
