According to my peaks guide book, Hollinsclough has some very good descents.

Has anyone been there, do you have pictures?

yes i have done a couple of the descents in that book, but it was quite muddy and part of a 32mile killer ride…to be honest i honestly cant remember them being ‘amazing’ descents…..like i said though conditions were poor and i guess in the dry it would be alot better!

These are very good if you’re in the area:
