the approach from Goodsprings is shorter (in terms of mileage, and time - 15 minutes quicker to/from downtown Las Vegas) and the road is significantly better than the approach from SR-160.
We came from Goodsprings and the route description was largely good except for the note about taking a right after the 1.3 mile distance. Maybe there is a bear-right at about that distance, but there is most definitely an actual road to the right at about that distance that could throw someone off. I had the parking spot noted on my GPS (thanks to the coordinates given), so could see that there was a better road farther north on the map going to the parking point.
So if coming from Goodsprings, consider going up the Haul Road, going right at 1.9 miles (this is the pretty large intersection with the left road going on toward Potosi) and then continue going north on that fairly rough road for somewhat over 4 miles. Then take a right on the obvious road heading up to the range.
