We stayed in site 12, which was rated as an RV campsite, it was pull through, but the hosts said mainly they use that area of the campground for tents with the RVs across the street (RV sites 1 - 9). If you are tent camping, the upper sites are really nice and secluded (20s - 30s). RVs cannot make it to sites 20s - 30s because it is a narrow dirt road to the top.
It's dry camping - no RV hookups, but at the visitor's center they have a water fill station that is free. You can pull in and fill up your RV water tank. There is no dump station at the park, nor in Glendive, so you have to drive to Miles City or Wibaux to dump. We found a Cenex in Miles City that had a good dump station and it was free.
The sites were spacious, clean and affordable. Sites 11 & 13 had a nice view. The bathrooms were pit toilets. Very clean. No running water. Camp fires are permitted.
The camp hosts were really helpful and friendly.
We spent one day in Makoshika hiking the trails with our dog. We felt that 1 day was sufficient, but you could easily spend more time to enjoy the park, take some longer hikes, or play disc golf. The other day we took a drive to North Dakota to check out Theodore Roosevelt National Park, about an hour drive away. Well worth the drive. We stopped at Beaver Creek Brewery on the way back to the campsite and brought back a growler for around the campfire.
They said next year they plan on expanding the campsites and adding in some full hook-up RV sites and a dump station. Even without that, we plan on coming back.
I'd book in advance if you are planning on going over a weekend. The campsites were all booked when we arrived. We reserved our spot about 3 weeks prior.
We stayed at DL Bliss State Park campground for two nights in August. The campground location is perfect, with access to beautiful beaches and hiking trails. From the campground you can walk to the start of the Rubicon trail. They have flush toilets and hot showers (token operated), firewood and ice for sale. From the campground it's a short drive to Emerald Bay State Park, and hiking trails in the Desolation Wilderness. Suggest an early start for those because even during the week the trail head parking fills early. Lots of shade at the campsites and plenty of trees to hang a hammock. We were lucky and all of our neighbors respected quiet hours. Bear lockers were available at each site, which were large enough to hold two coolers and a large Rubbermaid of food.
Holey Meadows is a small campground with just 10 sites. We reserved campsite 5 and there was shade all day long, which was good because temperatures during the day were over 90 degrees in the sun. There was a flat spot for our tent and plenty of room to pitch another tent. This site didn't have any neighbors behind it and it was close to the bathroom. It's a short half mile drive down a dirt road to get to the campgrounds. The camp host was friendly and helpful. He suggested a number of activities for us and came around each day/night to check in. He also kept the vault toilets so clean and aired out. Two thumbs up for that. All of our neighbors were really quiet and went to bed early. There's a number of activities in the area to keep you busy during the day - Trail of 100 Giants, the view from Dome Rock, the Noble Waterfall, and the Needles Lookout 5 mile hike. If you are in need of supplies, there's a restaurant / store 18 miles up the road in Ponderosa. We were able to pick up firewood and ice and had a beer on their deck and enjoyed the band. Overall, we were very pleased with our stay and would recommend it to other campers who don't mind no showers. Please note that there is NO drinking water as the description on this site states.
