Can someone give detailed instructions on the first few hundred yards of this walk? Following directions from elsewhere, I've successfully gone through the two gates, found the stone building, turned up the hill from there, found the rock with 'path' painted on it, then completely failed to find any way around the crags. Is there still a gate through one of the deer fences? I couldn't find it. What should I do after the rock with 'path' on it?
