From Hollins Cross there are 3 different (legit) downhill options!
I would climb up toward Back Tor (stop at the peak of the first hill) then go back down that descent and drop on to Hollins Cross – Greenlands. If you fancy a bit more climbing and a steep rocky descent, climb to the top of Back Tor and bomb back down the multi-line steps and rock drops, bit naughty I think!.
It’s a bit disjointed round there if you want to hit all the descents! It’s good to session and push back up IMO. Depends whether you like that kind of riding or prefer loops, in which case you can choose a descent and move on.
