Best RV Parks & Resorts near Grassy Butte, ND

Cottonwood Campground is a very nice flat campground with many sites. Some allow for pull through others for back ends. There’s also a nice tent space. The cost for a back and was only 20 bucks for the night which we thought was pretty good. There’s a picnic table and a charcoal grillavailable. There is no fire pit. I’m able to get some good signal with Starlink despite some of the trees. There are bison in the area, including one that was roaming in the campsite. It’s a beautiful park and a beautiful campground. There is water, but I have not yet found a dumping station at this site.

Two loops; the north loop is open year-round. The south loop is open mid-May through September. There are also walk-in sites and a group site, off the south loop. The campground fills up almost every day in the summer, even during the week. Odd-numbered sites are reservable while even number sites are first-come, first-served. We were not able to get into the site we had reserved (a nice pull-through with views of the bluffs and the river) because the people staying there the night before were having difficulty with their RV and not able to move it. We had been re-assigned to Site 38, a much larger site, but among the trees with no view. We were bummed but had no choice as the campground was full. We thought we might try to move the next day, but it turns out friends were able to join us, so our large site ended up being to our advantage. The pull-through in Site 38 was so large that it could have easily accommodated three large Class A motorhomes with room to spare! Large picnic table that was pushed up against the trees; we discovered the next afternoon that it was to take advantage of as much shade as possible. No fire ring; campfires are permitted in charcoal bbq grates or fully contained fire pans. Wood was not available to purchase at the campground; you must go to Medora(about five miles away) to purchase or you can collect dead and down firewood. Bathroom was clean enough with flush toilets but NO SOAP! No showers but we didn’t expect them in a National Park campground. Several very short trails in the park but the most popular Petrified Forest Trail is accessible from outside the park. Saw bison, prairie dogs, pronghorn antelope, wild horses.

The National Park North Unit and Campground(CG) is easy to find off US-85. We showed our Access Passes to get into the park and then proceeded to mile marker 5, where the CG is located. We pulled up to the information and sign-in board for this first come, first serve CG at about 11:30 AM Mountain Time(interesting that when we got to the north unit area, our phones went back to central time, and after a quick Google search, we found out that the north unit runs on central time). A gentleman let us know that he had just pulled in and grabbed a campsite near the entrance/exit and that we’d probably only fit in site 8(this CG is all dry camping) as the perimeter campsites, both back-ins and pull-throughs, were too short for us. The other longer sites were already taken. We proceeded to pull through site 8, which is a long, quarter moon-shaped asphalt site. We maneuvered around to stay away from tree branches and stay on the pad. The picnic table and stand-up barbecue were on the driver’s side, but since the sites are nicely spaced out, this was not a problem. We then filled out our registration envelope, placed $14 cash(Access Pass discount) in the folder, put the tab on our post, and deposited the envelope in the registration area. We could have also written a check or used a credit card to pay. We got on and off 1 bar on Verizon. We did have a good shot north for Starlink. They have a vaulted toilet and flush toilet building along with potable water at the dump station. There are about a half dozen sites for longer rigs, such as 32, 42, and 43, 49, with 5 being the best site. We had our two dogs with us, and there was plenty of room to walk them around the CG. There was plenty of bison poop in the CG, but we didn't see any during our two-night stay. Watford City is 17 miles north and has your major amenities. We enjoyed using this CG as a base to explore the North Unit.

Site was clean and well maintained. Campground offered pull through, pull off and back in Sites.

Bathrooms were very clean and well maintained.

Wildlife is everywhere. We were fortune to witness Bison walking through our site in the very early hours of the morning. Wild horses also visited the campground at some point.

Rangers we not only friendly but very knowledgeable. They were great with kids in ever setting taking time to educate them with facts about the park and wildlife.

We arrived before 3pm and were able to secure a first come first serve campsite.

Not only being in the heart of Theodore Roosevelt National Park, the town of Medora is a very family friendly place to explore.
