In my country, using Google Maps is nuts, hell, the official 1:50000 topomaps can often have errors - tracks marked on the wrong side of a creek, tracks marked that are only passable with a chainsaw these days etc. You'll never beat local knowledge. Go to the ranger station or visitor centre or hell, the local bar.
