We would recommend approaching from Longnor, Warslow or the A53 (which is the Leek to Buxton road), or through the village of Thorncliffe.
Do not rely 100% on sat nav. It will take you to Frost Lane (and then Little Fernyford Farm) which is half a mile north of our driveway. Please note that Fernyford Barn is situated at Big Fernyford Farm, and not Little Fernyford, which is quite close geographically, but accessed by a different road.
