This lane was photographed from the point where it branches off from
NS3676 : The road through Ardoch; this is also the location of the signpost that marks the start of the right of way.
The lane leads a short distance downhill, and then through a railway underpass, emerging at the shore. For another view of the same area, but looking back uphill from the other side of the gate, see:
NS3676 : Right of Way at Ardoch.
As for the right of way to Levengrove, much of the path, which is located in a grassy fringe above the shore, is often extremely overgrown with bramble stems and similar vegetation; depending on the tide, it may be easier either to walk along the shore itself, or to follow the edges of the fields that lie on the other side of the path.
