Go to the Woolley Bridge mini roundabout, turn right and follow the road past the Howdens factory and keep going. Go past next mini roundabout and carry on until you arrive at another 4 way roundabout. You'll see 'The Lamp' pub. Turn right and go up Station Road in Hadfield. You'll see Lambgates on the right.
It's the long way round but avoids the steep hills.
