Spot 21 is the best for privacy but the road is a bit rugged getting back there. I recommend a high clearance vehicle to enjoy. There are decent amount of campsites to pick from. Don't keep any valuables unsecured, as this campsite is a bus ride and a hitch away for the Boulder homebums. Don't mind the transient kids, they're just there. Campsite 15 also has a pond right by it if you want a bonus view while camped. Also, it's a good place to gather firewood.
