The posted coordinates are bogus - it would be difficult to get there even if you wanted to. To find the real coordinates you just have to visit a nearby cache - GC3XDPZ This is Yea Spur. The coordinates are in there twice just to be sure. Coming via that cache also means that you come in the best way.
If you come on a clear day the views from this ridge are quite something, as you will probably already have found out. There used to be a gate near the main road but this has long gone, and it is a reasonably easy drive.
