The campground is in a lovely setting. Loess Hills is a heavily wooded area on rolling hills close to Sioux City and has lots of nicely maintained hiking trails. The sites, on the other hand, are a bit odd, and the campground is really geared mostly to tenters. There's 8 sites on either side of the drive-in road which are all on one big grass area (so, no real separation between sites...it's just a grass parking lot). Only one side has electric. We're a 40-footer and just (barely) fit in site #8 (30 amp). A smaller rig came in after us and had to park at an angle to fit. The biggest electric site is #12 which is set up and away from the others. The rest of the sites are for tenters only. So, if you have a big-rig #8 and #12 are really the only options, and you have to be comfortable driving your rig on smaller roads to get there. It's one of the least-visited state parks in Iowa, however, so most of the time we were there we were alone which was nice. Overall it is a pretty setting, but a bit of a squeeze for big-rigs. There's central water, but no dump station. Showers and flush toilets available. Note it is very buggy this Aug. after record rains in July 2010, but I gather from the rangers this is unusual. We camped here in a Motorhome.
The campground has a lovely wooded setting in the Loess Hills not far from Sioux City. There are a number of trails that originate in or are very close to the campground. There is one very old washroom and a new washroom with showers. The facilities are great in the new washroom but the rough concrete floor gives it a grubby look. Only 10 of the sites have electricity. There is only one site with a level gravel pad. The other sites are grassy and more or less level. Do not come here if you have a big rig. Most sites would be unsuitable for even an average sized trailer. We camped on a weekday in May so the campground was wonderfully quiet. However, the sites are close together with nothing to separate the sites so it would be very crowded if the campground was full. We camped here in a Motorhome.
