Amazing views from the A-Loop campsites but the Biting Flies were as thick as... flies. (The Gnats were incessant too.) So essentially, it made the time from mid-day till 7pm really difficult to enjoy there in the campground. For our next two days, we made sure to be gone by then. We had stayed in sand gulch just down the road, over Labor Day and had problems with the flies also but we're hoping that they wouldn't be as bad earlier in the summer. We were wrong.
We stayed in site A2 which was a decent site and convenient to one of the vault toilets. Not a lot of privacy as site A1 shared the same general area for its picnic table and fire ring as our site did.
Another key thing to know is that the majority of the tent pads in the A loop are 9' square, which is smaller than normal in Colorado. There was no way we were going to be able to fit our hexagonal shaped tent on that tent pad. So we had to find some open space and that was still difficult to work with because there are a lot of rough, unevenly shaped rocks embedded in the ground all over the campsite which we couldn't avoid.
