Technically I don't think there is from that side. You can legally get fairly close from the bridleway through Ding Quarry which splits from Roolry moor road. I've come up the the Rossendale way a few times from your side, it is footpath but on the ground it is a wide track which takes you up onto the access roads. Worth going up as they are massive, much bigger than normal turbines.
If you fancy a fright, stand infront of one of them under the turbine blades facing the blades as they come towards you. Get in position without looking up, then look up, if you don't involuntarily duck you're a braver man than me.
