Camping summit county Colorado

Im looking to spend a few days camping in summit county. I really need to get away for a couple of days and clear my head.I am staying at my buddies place in Denver. Since I dont have a car here I will have to take the shuttle to wherever I go. So I want to find a place that is beautiful, not filled with rvs, and will be able to be accessable by car. Somewhere near breck would be cool, so that I don't have to pay a ton of money for the shuttle. Any recommendations would be more then appreciated.
