i live in todmorden and i have rode to lee quarry a few times, just start from todmorden and head towards walsden on rochdale road, and turn right at the arches which takes you onto bacup road, ride all the way up there and drop down into rottonstall/bacup and lee quarry is on the left near the big factory, ive rode there a few times, getting back is a pain as its all uphill lol, then downhill into tod so not to bad ;p
