the least cheeky of the options and imo the most rideable is best done if you are coming down the hagg farm descent first, though you can access it by going over the ladybower dam.
if you come down hagg farm, cross the snake pass and carry on down to the bottom. follow the trail over the bridge and round to the left and it starts to climb up to the bottom of the beast. at the right hairpin, go left through the gate which drops you down to the path that runs around the edge of the res. theres a bit of logging going on here but the guys are all friendly and will let you by without any hassle. follow the trail until you see a steep, straight trail heading up as the res path carrys on round. this is a bit of a slog but brings you out just down a bit from where you would be joining win hill the way you come up. take a right to hope cross.
like i said, you can access it from the dam but its a bit of a trek round the res, possibly still quicker than the road way though.
sorry i cant give you any features to look out for, i just know where it is! its not too hard to spot though. i think it may be a footpath but ive passed foresty people and rangers on my way up and they have just said hello so it may be unofficially allowed?
the other options as stated above are parkin clough and other similarly awkward climbs.
