We stayed at the Badlands Interior Campground and Motel for three nights while visiting Badlands National Park.  We were supposed to stay in the national park campground, but they had overbooked and we were out of luck, as were most other campers with reservations that day.  Fortunately, the Badlands Interior campground is just two miles down the road from the national park campground. They offer full hookups for the same price as a lessor site at the park campground.  

We found the Badlands Interior Campground to be enjoyable and convenient. We were in our class C while slowly making our way across the country. The campground is reasonably large. We had no problems getting a spot here. Sites are gravel for the RV, very level, and reasonably well maintained. All RV sites are pull through. Hookups are in good condition. You may have to run your water hose under your RV.  Each site has a grassy area with a table and fire pit. The grassy areas were a little narrow, causing your neighbor to be a little close.  Staff was very friendly and helpful. There are tent sites available.

There was a pool that we observed being used daily. There is a meadow with hiking trails at the campground. There are showers, laundry and a campground store.  Breakfast is also available.

The campground is conveniently located just two miles from the national park. It has great views of the national park. There is almost no noise other than your neighbors.

We had 4 bar LTE with Verizon. Our hotspot performed very well. The wifi offered at the campground is the best we have encountered.  My wife was able to play her xbox games in the evening.

We found this to be a great place to stay.  We will stay again when traveling this way.
