Of course, the most desired are the sites at Custer State Park in South Dakota. But, booking a site there is a real challenge, and have to book months in advance, and then hope you are one of the lucky ones to actually get in.
When we were there a few years ago, we stayed at
Buffalo Ridge Camp Resort. This is a Good Sam campground, so if you are Good Sam member (have a Camping World card), you'll get a 10% discount.
We were there for 2 weeks in July. It was sunny and hot! Our site was near the laundry facilities. My daugher and her family stayed in a tent in the tent area. We rented a Tee-Pee for them to stay in one night so the grand daughters could experience that too. Looking at their web site, it looks like they've expanded some of their services too.
Unless you are wanting to visit a park for the sake of the park, more than likely you'll be exploring the area so much, your camper will be used, basically, just for bedroom space. You'll be on the "go" so much, you won't have time to just relax and sit around a campfire. We were there 2 weeks, on the go by 8:00 am and not returning to the camper until after 10 PM ever day we were there. We did spend one day at the swimming pool or the granddaughters.
There is just so much to see and do in the Custer Area alone. You can make a day trip to the Bad Lands, Mount Rushmore, Needles Highway, Sturges, You've got the Black Hills National Forest, Custer State Park, Wind Cave National Park, there are wineries, candy shops, museums, animal habitats, you can rent ATV's, horse back riding, visit Deadwood (that's an adventure all to itself), and even the little town of Custer itself is a fascinating experience.
We were there 2 weeks and seemed like we barely scratched the surface of things available "to spend money on." This park of the country is not a location where you can simply camp and vegetate. There's just too much history, scenery, events, and activities. And when all else is exhausted, simply driving the Black Hills itself is awesome.
OK, Whenever the subject of the Black Hills come us, I get a really soft spot. Here's where I first became intrigued with the Black Hills of Dakota!
(PS, we also have a bottle of Buffalo Bill Wine and another bottle of Calamaty Jane Wine as a souvenir. We'll never drink it.
