Sully Creek State Park

A peaceful place near the river with access to coyote howls at night as well as a section of the Maah-Daah-Hey Trail.

The Whitetail Flats Area, which has electric, can fit any size rig very easily. The sites are spaced far, far apart and are pancake-flat.

The Cedar area is primitive and more treed and the sites are closer together. Our 25 foot box would have fit in some, but not all, those sites and the overhanging limbs would have been a little challenging with our 11 foot roof.

The showers give great hot water for 12.5 cents a minute.

You must reserve online for camping thru the NDSP site.

(Stayed 9/14/20). This campground is really 3 areas in one state park. Whitetail Flats, where we camped, was a wide-open area without trees for shade. We had a corner site that was back-in (one of the few) so we had trees on one side and a view of the mountains and fields behind us. Seems like private land was behind us, separated by a small split rail fence. The site was very private, level, and had plenty of space. The campground was very quiet. Deer wandered around in the woods next to us each night. We did not use the restrooms or showers so no comment there. Dump station had potable water as well. An added bonus was the recent installation of electric hookups which, I am guessing was done so that in the warmer months, campers don't have to run their generators.

The other 2 areas are quite different than Whitetail. One is a horse-only area. As the CG is right on the popular Maah-daah-hey trail, many campers were staying with their horses. The other area, Cedar, is heavily treed and was much cooler. Our friends site (22) was not too level and not much of a pull-thru with trees guarding each end of the site. But, it was nice and shaded. The Cedar area does not have electric.

In addition to the camping fee, you are supposed to pay a $7 a day state park fee (which we did). There was no host in the CG but the ranger station is adjacent. You are able to purchase wood from the ranger.

Sully is convenient to the town of Medora and the south unit of Theodore Roosevelt NP. We had planned to camp at TRNP but the campground did not open during the Summer of COVID. It was good we had a reservation at Sully as the campground was full. Our friends booked the last available spot and that was about a month before our arrival.

The good news is that Whitetail flats campground sites now have 50 amp electric! Good thing because this campground is not shaded and you may want your a/c in summer. Sites are level and are pull through, looping off the road. Sites here are very far apart. Pay showers and pit toilets.
Folks should know that the privately owned Red Creek campground at the edge of town is adjacent to a railroad track with a fair amount of traffic.

The place was okay and most likely more desirable during the regular season however being there in the off season it felt a bit expensive for a place with no amenities. Paying $7 day use fee over the $12 camping fee at the end of October was, for me, a bit too much. That said, one other person was camped in the entire place so that was nice.

We paid $19 per night ($12 for camping and $7 for day pass). From the previous reviews, I didn't think this campground would have a lot of traffic, but it did while we were there (nights of September 10-14). The night of the 14th, both the Whitetail Flats and Cedar campgrounds were full. Campers were parking in the horse corral area. There is a .4 mile dirt road to reach the entrance to the campground. The road had some ruts/potholes, but was manageable. There is a self pay station at the entrance to the park. The board with the list of available campsites was not updated regularly during our 5 day stay. It's probably best to check online to see what's available. However, if sites are reserved for a particular date, the park ranger puts a note on the post with the dates. Interior roads of the park are dirt/gravel and sites are either dirt/gravel or hard packed dirt/grass. Sites are flat and fairly level. There's easy access for big rigs. We stayed in the Whitetail Flats campground. Sites in the Whitetail Flats campground area are spacious. I believe site 1 is the camp host site. Sites 2-6 are clearly pull-throughs on dirt/gravel, but sites 7, 8 and 9 could be either pull-through or back-in; they're on hard packed dirt/grass. Site 10 is a pull-through on hard packed dirt/grass, although it could be a back-in for a very short RV. The campground is very quiet and peaceful, but it can be a bit dusty. Cedar campground has a 40' wide, 10' height limit, but we saw 5th wheels that were higher than 10' in that campground. Cedar campground has many trees; sites are relatively spacious there too. Little Muddy Breaks sites have horse corrals at each site. There is a vault toilet in each campground. The dump station/water fill is conveniently located and has easy access. Verizon cell and data worked fine for us while there. All in all a beautiful place. We would stay again if passing through the area.

I would actually choose this campground over staying in the park. It is very close to Medora, so you can enjoy this unique town as well. (the musical is a must...)
We camped in the Cedar campground, which is heavily treed and quite private. Our site was very small and would barely fit our 25' trailer, but we managed. Other sites would have fit it better. As someone else mentioned, it is a tight squeeze around the loop, so you may want to scout ahead before bringing your rig around it.

It is a unique park in that it accommodates large rigs in the Whitetail Flats Campground, horses in yet another campground, and the rest of us in Cedar campground. There is a 96-mile bike/hike trail that starts at the park.
We had a tremendous thunder/lightening storm one of the nights we were there, and a sad number of people in tents were throwing their entire tent away the next morning. It was scary enough surrounded by aluminum!
The signage from the highway is poor to non-existent. Our GPS brought us in through a long gravel road. We got there eventually, but it is much shorter driving through Medora.
My only complaint were the showers. It was nice to have them, but mine was far from clean. Other people mentioned they were clean so maybe I just hit a bad day. Otherwise, lovely place.

Our huge, incredibly private site was just minutes from Teddy Roosevelt National Park, but unlike the NP campground this park has showers and a dump station! The park has three campgrounds: Little Muddy Breaks (must have horses to camp here), Cedar (shaded and private), and Whitetail (large, open, grassy area). We stayed in Cedar and loved the VERY private sites, which had tons of trees in between but still enough open sky to generate plenty of solar power. However, bigger rigs MUST pay attention to the length and height limits posted at the entrance to this area. We watched a 5th wheel rip its A/C off the roof passing under a low branch. The turns in the Cedar area are also very narrow with trees close to the loop. The Whitetail loop is basically an open grassy field, with sites designated by the gravel parking spots and the picnic tables, so this is the place for large rigs. The open field has great badlands views and incredible dark skies at night, but obviously no privacy between sites. There is a trailhead for the Maah Daah Hey Trail right in the park, and Medora (and Teddy Roosevelt NP) is 5 minutes away. The bathhouse was immaculate, with showers priced at $1 for 8 minutes -- which was plenty, with nice hot water. For the overall price of the campground, we thought it was a great deal especially compared to the Cottonwood CG inside the national park. The only downside is that we had no service on AT&T, even with a booster. It's possible that we might have been able to get a boosted signal from the Whitetail CG area, which is a little further away from the canyon wall.

After traveling a mildly bumpy dirt road, check-in was a breeze, as soon as we figured out where to do that. The host was super nice and helpful. We got a little lost trying to find our site but it provided a nice tour of the whole campground including the horse corrals in the Little Muddy Breaks loop. Once we found our site we had to kick some day-use people out of it but they kindly moseyed. We had a pull through site in the Cedar loop. The sites in this loop are super private and of good size. You have to drive around the Whitetail Flats area which is basically a wide open area, great for large groups. Our site was right on Sully Creek which is a small creek but provides lots of vegetation and wildlife including whitetails right in our site in the morning. The site also provides a great view of some North Dakota Badlands. I really enjoyed listening to the horses in the corrals nearby and thought the donkey we could hear was absolutely hilarious. It was as if he knew the quiet hours. We used this as our base camp in the middle of August to explore the National Park and I'm so glad we did. I would have loved to stay longer.

Very quiet campground catering to horses but camping sites also available. Excellent steel panel fencing for most sites with cleanup tools. It had rained for a couple of days before we stayed so the access road was very muddy but the campground was well gravelled. $1 showers for 8 minutes. Plenty of time to get clean and very nice hot water. Close access to the national park where we seen buffalo and deer. Park officer was very helpful.
