I didn't do much on the gravel side of things (a bit near Symonds Yat and Tintern Abbey, you could tweak the route to do more if you wanted) but I did a great trip a few weeks ago - train to Bristol Parkway open return (so did a modified route back the same way the next day), cycle over the Severn and up the Wye Valley and then across into the Brecon Beacons, up over Hay bluff towards Hay on Wye to camp out. Roughly reverse course the next day, taking in some of the different bits in the Wye valley.
Beautiful scenery throughout and really varied. Can dig out a GPX route when I get a chance, but I was really pleased with how well the trip went.
