Camped late April for 5 days, so it was offseason one pit toilet open one water spigot open in the campground.  There are two loops, the south look which is tenting and smaller sized trailer sites but it was not yet open while we were there,  The North Loop is mainly pull through sites and can handle larger sized RV's.  This is dry camping, there are no hookups.  You can experience some nice hiking and opportunities for wildlife viewing.  Buffalo were common visitors while having coffee in the morning.   Elk, deer, wild horses were common as well as hawks and prairie dogs.  Currently Western North Dakota is experiencing a drought, and being early in the season for the campground, it was dry and dusty but did not prevent us from hiking and exploring the park.  There is a convenience store in Medora ND right outside the park entrance that you can purchase basics but there was no grocery store.  Part of the scenic loop drive is closed due to road erosion but you can still travel most of it though its an out and back with turnarounds for larger vehicles. We would defiantly camp there again, but if you need the luxuries of an RV "park", you will not find that here.  The campground is well maintained and clean.
