I used to drive for hulleys and my favorite places were monsal head, used to love driving down into the valley, and Youlgreave/youlgrave (even the locals cant decide on the spelling and road signs use three or four variations) theres a lovely walk in youlgreave by the side of the river that continues up to middleton by youlgrave and past some old sheep dips, then come out onto the road and walk back down to youlgreave and the George hotel do lovely takeaway chips and a pint. (Not while driving a bus obviously)
