Stayed for a single evening and was near the city center.

Wish there was a little more shade at the campsites but otherwise it was a great stay! Clean showers, good cell signal, friendly staff, easy access. Within walking distance to Wall Drug mall/restaurant/gift shop if you should find yourself so inclined. Would definitely stay again if in the area.

At the last minute, we decided to overnight in Wall SD as it was very hot for boondocking. We found Sleepy Hollow and we weren’t disappointed. We got a electric/water gavel site which was just a little low in the front. The campground was full by the end of the night. We had 37 OTA TV channels and ATT was 2 bars with 12 up and 6 down for speeds. Very close to downtown Wall so you can check out the tourist trap!

Centrally located and one of the only games in town but it's truly just ok. Sites are on top of each other. It's a great base camp for the Badlands but we will boondock or try another spot next time. This is really only if you must have the full hookup otherwise I would try elsewhere.

We were dispersed camping overlooking the badlands when the rain and extreme winds was more than we can handle. To compound our crisis we had a broken leaf spring on the trailer. When the leaf springs were being replaces the mechanic said 3 of the tires were separating. A tire shop could not get our tires until Monday and the campground was closing on Saturday for the season. Michael at the tire shop contacted the owner of the campground and help arrange a 2 day extension.

Sites are a bit close together, but very quiet and nice campers. Bathrooms and showers were very clean, which is our number one take on campgrounds. Easy walk to downtown too. Would highly recommend when traveling off the interstate for a good night rest and checking out the area...

I'm throwing the three stars because when it was good it was pretty good, and when it wasn't, it wasn't. The good: - Convenient to town. - Friendly staff. (with exceptions; see below) - Easy in and out from I-90. - Well-equipped camp store. The opportunities for improvement: - They lean hard on the "Heated Pool" but (see photo) it doesn't live up to expectations. - Nothing approaching shade in most sites. And the Dakota sun can be brutal. - Many sites don't have full hookups, but you pay basically the same for sites that do. - I've paid a lot less and received a lot more at many other campgrounds. One thing that irked me from the start. Their website has no information about check-in and check-out times. I pulled in around noon and was very rudely told I needed to leave and come back after 1PM. Noted was that a) my reserved spot was empty; b) lots of other spots were empty, too. I asked if I could just pull in to my spot and settle up after 1PM but I was pretty much told, Go somewhere else; maybe there are empty spots in the Wall Drug parking lot. To be honest, this didn't make the best possible first impression and I would have cancelled my stay were it not for having been prepaid and non-refundable at this point.

Stopped by after boondocking at the wall to use the dumpsite. Excellent dumpsite and cost $20.

Last minute reservation so 30 amp is all they had. Great location and good-sized dog park. We have no slide outs, but noticed a few sites had trees obstructing some rigs’ slides.

This campground doesn’t offer all it promises, there wasn’t a pool available and the wifi is pretty spotty. The dog park was excellent. The power 30/50 amp was consistent. About 1/2 of the campsites don’t have septic, but most of the campers are there only 1-2 nights. Sites are pretty close to one another, but we expected that. When coming into the campground use exit 109 and not 110. You wouldn’t want to navigate your RV through Main Street. There is train activity early am and early evening. Wall Drug is walking distance and the badlands park is just south of town. We also went to the Minute Man Missle Museum while we were there.

Right across the street from Wall Drug. Easy hookups and clean facilities. Polite and courteous staff. Great stopover location.

Sleepy Hollow was a nice little campground. Across the street from Wall Drug Store and a short drive to Badlands National Park. Friendly check-in service. Nice level pull-thru spot.

Stayed 8/18/20.  This campground is within walking distance of Wall Drug.  It is also in close proximity to Badlands National Park.  We stayed in a full hookup.  The facilities could use some updating.  Our site was clean though and our one night stay was quiet.  It is sufficient for an overnight stay.
