Look out for the Shell filling station on the edge of Newtongrange and Gorebridge, and turn down the hill in front of the garage, then look out for Dalhousie Castle.
For most people, the best route into Grove is via Sherriffhall roundabout, then down the A7, turn right at the Hardengreen roundabout, and first left at the un-named roundabout half a mile later. Turn left onto the farm track when you see Dalhousie Castle on the left.
The range is on the opposite side of the road from Dalhousie Castle, although they share a common entrance. Parking is marked by a small sign near the end of a farm track, just before the track dips down hill. The range itself is through the gate at the back of the carpark (head towards the tree-house), then a further 100 yards or so downhill on foot, or you may drive all the way down if you cannot manage the hill. (Please leave the gate clear for those who need it!) Access has been much improved since we first moved in - welly boots are no longer needed!
