Sully Creek State Park

This is a very pretty park only about three miles from Medora. The sites in the Whitetail campground are very spacious, most are pull thru, and they have electricity. The bathhouse seems almost brand new and the showers were spotless and functioned perfectly. The toilets are in a separate building and are vault toilets. There is potable water on site. There is an extensive hiking trail which runs right by the park and the hike to the south was particularly nice.
All in all, a very nice state park. Cell service is minimal but a mini antenna made it usable.

I can’t review the horse camp in the back of the campground, but the front loop where we stayed was unpleasant. It’s just a big open field with almost no shade, but lots and lots of red dust. The loop around the campsites is essentially a dirt road, and every vehicle that goes around kicks up a large cloud that covers your rv. In addition, the ranger who collected our daily fee for the privilege of entering this “park” didn’t bother to tell me, as I learned at the next ND park at which we stayed, that I could save by purchasing an annual pass at the senior rate. I also received no receipt for my cash payment?

This is a great place to stay near Theodore Roosevelt National Park and the little town of Medora.

Pros: Spacious, electric, clean and free (for now), right on MahHahDee Trail. Water available (not a hook-up). Dump station.

Cons: Pit toilets (clean but still…), lots of flies (see pit toilets), website seems to advertise water hook-ups but that is not the case.

Very dry and dusty when we were there. Great wildlife at TRNP. Horses can camp on one of the loops so lots of horses around. Serenaded by coyotes.

Campsites in Whitetail flats are very large. Some tree coverage on peripheral sites. No shade in center spots. All pull through.

Sully Creek is a great place to stay when visiting Theodore Roosevelt National Park. Just 2 miles out of Medora, it's quiet and beautiful. The Whitetail Flats area can accommodate large rigs, the sites are spacious and the electricity is needed for hot weather. There is a dump station and potable water available, but only electric at the site. Sites 7, 8 and 9 are all really nice with great views of the butte. Site 8 has a couple of trees, perfect for a hammock, The shower house is cleaned daily and contrary to the website, free.
The Maah Daah Hey multi-use trail is right next to the campground. We enjoyed walking along the Missouri river, through a forest, across pastures and into the hills. Very nice and dog friendly. I highly recommend reserving early as there are only 9 sites with electricity and they were full every night we were there.

The park is a great option if you can’t get into TRNP or don’t want to for some reason.

Site 14 is a wonderful site for tent camping especially. One obvious spot for your tent is nestled in the trees. There’s another potential spot a little deeper in the woods. The other spot doesn’t have as much privacy as the other two potential spots for tent camping do.

There was some poison ivy encroaching the site in several places.

There is water near the entrance to the tent camp area however from site 14 the only bathroom nearby is quite a bit of a walk. Maybe we missed one closer but the only bathroom we found anywhere close by was over by the horse camp. The map online confirms it.

There was a fire ban in effect when we were there which nearly everyone ignored. There was no park staff around when we arrived after 8 pm to alert. Most people respected an idea of quiet hours but it was not the quietest camp site I’ve ever stayed at.

Nice park. Open space. Price was $25/night plus a $5.80 for a booking fee, which is a bit steep for electric only... but it was a great experience. There is potable water on site and a dump station. Toilets are only pit toilets, but there are pay showers that are in good condition with hot water. There are a couple of other campgrounds that are a little closer (the area is small, so everything is really close); we might have considered one of those if we needed full hook ups that night... but because electric only was fine for our stop, it was a good choice. We walked through their tent campsites and they have some really pretty ones.

No At&t. Strong Verizon.

The following information about Alfred Sully that I found interesting is from Wikipedia https://en.wikipedia.org/wiki/Alfred_Sully

Afred Sully was a Civil War general in 1861.

After being relieved of command, Sully went west and gained notoriety for committing several massacres against natives. On September 3, 1863, at Whitestone Hill, Dakota Territory, as reprisal for the Dakota Conflict of 1862, his troops destroyed a village of some 500 tipis that lodged Yankton, Dakota, Hunkpapa and Sihasapa Lakota. Warriors, along with women and children, were killed or captured. The troopers' casualties were small

From September 1856 through May1857, Sully was posted to Fort Pierre, Nebraska Territory (now South Dakota). He met and, by Sioux tribal custom, married a young French-Yankton girl of the Yankton Sioux tribe. With this marriage, Sully became the son-in-law of Saswe, a.k.a. François Deloria (Saswe being the Dakota pronunciation of François), a powerful Yankton medicine man and chief of the "Half-Breed band".

Sully's daughter by his Yankton Sioux wife, Mary Sully, was known as Akicita Win (Soldier Woman).[6] She married Rev. Philip Joseph Deloria, an Episcopal priest, a.k.a. Tipi Sapa (Black Lodge), a leader of the Yankton/Nakota band of the Sioux Nation.[7] Tipi Sapa is featured as one of the 98 Saints of the Ages at the National Cathedral in Washington, D.C., as the first Dakota Christian minister to his own people.[8] Among their descendants are Yankton Sioux Ella Deloria, an ethnologist, and her nephew Vine Deloria, Jr., a scholar, writer, author of Custer Died for Your Sins[9]

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.
