Been there, loved it. It was on my cross country bicycle tour, in 2004. My story about that part starts here: https://www.crazyguyonabike.com/doc/page/?o=1fs&page_id=12746&v=4C

It has been close to 50 years ago, but we stopped at Wall Drug. Just because.

it's on my bucket list :-) Please let us know how it was.

Reptile Gardens is fun and has some neat stuff.

Been to ALL those places. Jewel cave is excellent....loved the cave bacon! Custer State Park for the buffalo herds. Needles Eye...watched climbers. Pig Tail curves, I have a post card pic of it. We stayed in Hot Springs and went to a local river where the local Indians hung out. Shopped for local Indian pottery, BIG water slide, little cafes. Hickabilly restaurants with clever menus and place mats I brought home.....

Sounds like a great trip. I'm going to Switzerland in August.

Take a drive through the South Dakota Bad Lands. There will be photo opportunities. The shadows in the formations shift according to the position of the sun.

A short distance west of the SD border is Devils Tower in Wyoming.

The world's biggest motorcycle rally is in Sturgis, SD. I'm not certain of the date. Google it to find out. During that week, the main street in Wall, SD will be parked full of motorcycles. Many of the riders will be visiting Wall Drug.

Sioux Falls: There really is a falls there. It consists of series of drops. Its not spectacular like Niagara Falls, but is quite scenic.

Husband and I went to the Sturgis motorcycle rally many years ago. We traveled around the state for almost a week following the rally. I'd love to go back some day but it would be in a car or motorhome this time.

Mt. Rushmore is wonderful and the Crazy Horse Memorial is just fabulous and you will love them both, I think. We just went there last September and I crossed Mr. Rushmore off my bucket list. I knew very little about Crazy Horse and it is quite a spectacular monument and the history amazing, very moving imho. I wish I could come back in another generation or two to see it all finished.

I don't how close it is, but I went Devils tower when I was in that area.

Sounds wonderful! Have a great time, have never been there.

I also liked the badlands. I really like landscapes.

I forgot when I was making the list that on our way the Badlands will be our first stop. I will be picking my daughter up in KC, so we probably won't arrive with the rest. It's bound to be a lot of fun. I tried talking my sister into joining us, but I doubt she will.

Sounds like a good time. I messed up when suggesting the badlands in SD because I have only seen the ones in ND. I bet they are just as great and I think I liked them so much because I have never seen a landscape like that before.

I suggest Wall drug also. If you don't know the story behind it see if you can find it.
