We were here on a Sunday night in late August. Not at all crowded. Really nice grounds and well maintained facilities. HOWEVER, the "bug problem" described by several people in the reviews below was significant. Thousands of mayflies came out, mainly in the evening, swarming lights, swarming the bathhouse, flying in your face, sticking to your skin. We could not swim in the lake -- there were too many dead mayflies. We trying using the bike paths in the day, and again hit swarms of these things. They don't sting or bite, but it was horrible. We will never go back to this campground. I really hope this is just a late August phenomenon,. I recommend that you call the park before traveling, to make sure that these bugs are not present during your visit.
The views of the badlands are breathtaking. The evening star show in the amphitheater is fantastic. This was my 3rd time camping here -- once in a motorhome, once in a tent, and now in a tent trailer. Honestly, I had forgotten the grungy bathrooms, lack of showers, lack of water access (can get to it only with an extra long hose), hot sun, and dusty wind. I had forgotten that you just park on the road and call it a "camp." I had forgotten that you open the door of your camper right into the passing traffic. All I remembered was the breathtaking sunrise, sunset, and surrounding landscape. I hope that is all my husband and daughter remember in the end, as well, although given the miserable camping situation, it's going to take some time. Try to come here in the off season. The campground would be much nicer if you aren't parked end to end on the road with a bunch of other RVs.
There are multiple campgrounds within Custer State Park. We stayed at the Game Lodge Campground. Please read the other reviews below: we agree with the others' comments. Very nice campground, lots of grass, lovely stream, small pond for kids to swim in, paved trail leads up to the Lodge, a store, and the visitor center. There's a wooden fence separating the camp from a large field in which a herd of buffalo came to graze multiple times during the stay. Bath house was sparkling clean. We made good use of the laundry facility. No problems filling the water tank. (I think the new dump station must have taken care of the water issue the previous campers described). Mosquitoes were gone by late August. Advance reservations are needed, at least in the summer. Booking a month in advance, in all of Custer SP, we found only two sites with electric available for the dates we wanted. When we were here, all of the reservable campgrounds appeared to be full. However, the one campground for same day camping (not reservable) was only about 20% occupied during the weekdays, so would be a good alternative if you have an RV that can boondock. Pit toilets up there might make it a less favorable choice for those of us using the public restrooms.
This is nice looking small to medium size reservoir lake located in the country, far from busy roads. The campground host was very friendly and we enjoyed the "free format" camping. He told us to feel free to drive on the grass and camp anywhere that was not otherwise signposted. There were only a couple of other people camping here that night, so we had a lovely view of the lake and enjoyed a night of boondocking. Despite the 2009 reviewer, we did not see any evidence of a separate campground with hookups, nor was this mentioned by the host. Detractors were: not much of a swimming area (better boating lake). A moderate amount of trash was scattered around the campground and some had evidently even been mulched by their mower. The bathhouse met only minimal standards for cleanliness. There was dirt around the edges everywhere, paint was not well maintained, big spiderwebs all over, no soap provided. Hot showers were available but you had to pay for them with quarters. The dirt (not gravel) road is heavily rutted. It looked like a heavy rig could easily get stuck in wet weather. Another camper told us that the whole place is full during the high season. We would have found that to be pretty miserable given the status of the park and facilities. For an overnight visit in the off season, however, this was a pleasant place to break up a long drive.
