the road up toward Boulder City is indeed pretty rough and you will want a high clearance vehicle if you want to drive very far. I drove to about 7900ft and from there it was a little over two hours hiking to the summit via the north slopes and northwest ridge. This is a simple class 2 hike and the rock is firmer than often found in the Boulder mountains.
