I'm in Nth Cornwall but regularly drive to Redruth for work and leisure, and would love to hit the trails down that way - the Camel Trail is beautiful, but I could do with a change and more challenging terrain (not too challenging!)...
If you go just a couple of miles north from Redruth towards Four Lanes and find the Great Flat Lode trail car park you can do a nice out-and-back to Bissoe via Carn Marth and ”Mars” (or Wheal Maid) near St Day.
