Not sure if this comes under Edinburgh. As you drive up past the top of Ratho Station towards Ratho there is a bridge that goes over the M8. Just over the bridge on the left there is a turn. Left turn in then left turn again takes you to a field and gate. Hedges for privacy from the road although there is a driveway up to a house if you take the right. Used several times and always a car or two, usually after dark
