If you’re parked in the plantation car park, the only ways to go are either down the road to Bamford Clough then either North to the Cutthroat Bridge loop (not at this time of year), or South (then west) to the Hope valley (looks like miles away, but it’s on the road and flat ish so you cover it in no time) and you can ride any of the loops from there, then ride back up the road to the very top and do the stanage loop.
Or you can go left out the car park, up the hill and heat towards lady canning plantation (again a long old road ride, but over in 15-20min), ride accross houndkirk moor on the roman road, turn left down the narrower path to Blacka Moor, do each of the bridelway runs (there is no best one IMO), then ride back via the outdoors center at the far end of houndkirk. From Lady cannings, rather than going SW, go NW past the lama farm, follow the footpath down past the resevoir, and back tot he road (just cuts the road corner), follow the road to stanage and over the top and down the plantation (turn left across the moor just after the pole IIRC, it’s sometimes harder to spot the path as the start isn’t obvious from the roman road).
