Difficult to find entrance road; small sign just says "camping." Access over un-signaled RR tracks, then down long country lane that looks like the wrong way; pass through unmanned kiosk (manned and locked at night); watch for close-in tree boughs and dips in gravel road. After sign-in at office, a quarter-mile drive through the heavy woods to camp sites. But it's all worth it! Huge drive-through sites between tall, mature shade trees, just park on the grass within reach of utility hookups. DuPage River runs along edge of sites, and there is a boat ramp. No street lighting, so nights are pitch black and the whole camp is super quiet. Some long-termers have been there for years. Enterprise car rentals will pick you up at your coach! It makes a great base for exploring Chicago or just taking a few days off the road to relax. Medium expensive, but considering location, it's a good choice and a really nice and secure place to recharge for the road.
Expensive, but considering the proximity to DC, it makes a good base for exploring the capitol. A very short walk to in-camp bus terminal, where you can get shuttle bus to DC Metro system; if I recall correctly, 90 cents for seniors on bus, and then transfer to DC Metro rapid transit for about $2.50 to downtown DC. Total time is about 45 minutes each way. Campground is very tidy and very marked and delineated (just follow the colored line to your parking area!). Most people seem to be there for a few weeks; sites are not all pull-through, but backing in is no problem for me; site sizes were very adequate. Altogether, a nice, pricey, urban, very regulated campground. Surprisingly quiet after dark, although you could sometimes hear a semi on nearby freeway ramp.
A bit difficult to find the campground entrance (Vidalia was doing street modifications), but the small hassle was well worth it. The RV camp is on a flat bluff above the west bank of the Mississippi River, with a beautiful view of a long stretch or river. Sites are large; grass, gravel or concrete pads. Easy access with most sites pull-through. Very quiet, except for occasional river towboat (upriver will take them 15 minutes to pass by). Only 10% occupancy the night I was there. I will definitely stay here again.
Have faith, Hermosa seems a long way South of Rapid City, but they are on the right just after SD 40 & 36. The campground is official South Dakota; a rolling hillside with 20-mile views and a big sky, trees are just shrubs. Very easy access and pull through sites, all very level within the campground. Wi-Fi reliable. Nice and dark at night, but proximity to SD 79 allowed for noise from occasional semi climbing the grade in front of campground. We asked for directions to Mt. Rushmore, and they routed us up SD 36, the wrong choice for a Class A (low clearances), and we had to backtrack all the way back and then take the correct SD 40! They ought to have known better about their own local roads! Still, a nice park and I would use them again.
Have faith that they are down the small country road just beyond a mobile home park on the left (south) side. Also, watch out for the tree boughs that will hit a Class A. Park itself is very nice; although, I didn't see any of the mature trees in their pictures. Site access was easy. We were placed right along the East perimeter, which is a wall of tall trees, so we at least caught a little shade in late afternoon. Commons area was nice, and we swapped a few jigsaw puzzles and books. Campground was very quiet and dark after sunset. It felt like a country hideaway. Only about 30% full the two days we were there. I will definitely stay there again.
Generally good park. It was so hot (107F) and the shore power was perfect to run our AC. Easy access, but park entrance is easy to overlook. Quiet locally, but light sleepers will have a problem with the very near railroad. Deming moves a lot of heavy rail freight and all night long you will hear, and sometimes even feel, the rumble of freight trains. I didn't see any shade; but hey, it's New Mexico. My wife used the showers; came back happy & clean, so I guess they are OK.
