First off, this campground is a little strange. It is owned by the City of Boulder so campers have to follow the open space and mountain park rules, as well as state alcohol laws. Only 3.2% beer is allowed and no glass. This campground also goes by two names. Buckingham, the actual name, and Fourth of July campground, the name it has in Google Maps. There are only 10 sites at this campground, but it is free and first come, first serve. The campgrounds only have picnic tables, that's it. There are toilets at the Fourth of July trailhead, which are right by the campground. Overall the campsites aren't much. The only reason you'd camp here is to get an early start on one of the trails from the Fourth of July trailhead, which is what I did. I did the hike to Diamond Lake, a 5 mile round trip hike to an alpine lake in the Indian Peaks Wilderness. The hike was beautiful there were waterfalls, wildflowers, and dense forest. I know that you can also backpack and camp overnight at Diamond Lake with a permit.
