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.
"Nothing in this world can take the place of persistence. Talent will not; nothing is more common than unsuccessful people with talent. Genius will not; unrewarded genius is almost a proverb. Education will not; the world is full of educated derelicts. Persistence and determination alone are omnipotent. The slogan "press on" has solved and always will solve the problems of the human race."
