In reply to Jamie Bankhead:
I think that's right to make that assumption. The first time I climbed there might well have been during a logging period and as a result they left the gate open to save opening and shutting it which at the time I took to mean that it was an open gate. I have walked up there since and found that post logging the lorries had churned up the track so much it would be hard to get a car up there.
Apparently the key for the gate is the same as the Ben track one ! !
