This is in my top 5 most beautiful places I've ever camped. The roads leading up to it are definitely most manageable in a vehicle with 4x4 or good clearance and there are some very exposed, narrow sections to be wary of depending on the route you choose. There are a handful of marked sites up at Paradise Divide (as all dispersed camping is now regulated and marked in Crested Butte area). If you are arriving on a weekday you shouldn't have too much trouble nabbing a site, but weekends in the summer may not be easy to get a spot. These sites are located very close to some of the best mountain biking trails, the 401 and 404, as well as a wealth of high mountain hiking.
