I'm not sure what his way is but if I were staying in Gunnison I would take the highway on the north rim of the canyon. Go to Blue Mesa, and when you get to the west end of the lake hang a right and go across the dam, that highway takes you right to Crawford. It's kind of a windy road the first half of it,but a beautiful drive, and as far as I know the shortest way from Gunnison to Crawford.
