YELLOWSTONE TRIP

make sure you go to the tetons, they are just to the south and much nicer in our opinion than the park. There is the national elk refuge and the visitor center is great. We stayed at the KOA just on the river in jackson and day tripped teton and we had driven through yellowstone from the north. We have been there before so didn't spend much time this time, but it was our 1st for the tetons.

If in Hill City, if you are interested in natural history. The Black Hills Institute is a must see.
Lots of dinosaur skeletons, including T-Rex.
IMHO worth the trip just for that.

We've always found Madison campground to be about the most convenient for MOST of the park. The park is larger than some states so the most CENTRALLY located would depend on what type of things you value the most. Madison is convenient for geysers and fumaroles plus lots of other scenic areas like Fire Hole River area. If you plan on spending most of your time in the Northeast part of the park (best for wildlife viewing and visiting the Canyon area) then the Canyon campground would be a good choice. If you feel you must have full hook ups then be prepared for parking lot like camping only. A better option would be just outside of the park at West Yellowstone. Camping is cheaper, MANY more choices and in some cases a much more "camping like" experience. You WOULD make it more inconvenient to attend the myriad of GREAT campfire / Ranger presentations available at most inside the park campground. There are also several really nice COE / NFS campgrounds located only a couple of miles north of West Yellowstone. Very convenient to visit other area attractions like "Quake Lake' which is the site of the huge earthquake of some 60 years ago.
Good luck and have a great trip / Skip

While in the Black Hills/Mt Rushmore area I recommend staying in the Hill City area. Several nice campgrounds, both commercial and State parks nearby. Well located to do and see everything in the area and has everything you need (groceries, shopping, wineries, etc). While in Yellowstone our favorite campground is Mammoth. No hookups but the elk and scenery are worth it. Also agree with previous poster about Yellowstone's Edge- great CG but it is a ways from the park entrance. But once again the scenery is terrific. Have fun!

One of the surprises on our trip west last year was finding Teddy Roosevelt National Park, We intend to make it a destination next year.

The last time we went, we took a trip to the Little Bighorn Battlefield where George Custer met his demise. Very interesting!

Please turn off the caps (notice nobody else is using them..)

Welcome to the forum. Lots of experienced campers/travelers on here. Wherever you go and whatever you want to do, somebody's already done it.
Weatherbase is a good resource for your travels. All kinds of weather averages by month over many years for just about any place in the country. Free to use.
Perryville, at 522 ft. ASL has very different weather from YNP at 7,938 ft. ASL. in September. Be prepared for possible snow. Not likely, but possible. Certainly colder, especially over night. Take a coat.
BTW, posts are easier to read if you turn off CAPS LOCK.

Welcome to the forum. Please turn your caps off so you are not yelling. Yellowstone is probably our favorite national park and we have been there several times. Last year we were there in early September. It was still crowded, but not nearly as bad as in June, July, and August. We enjoy Fishing Bridge Campground which is in the park and has full hookups. Spaces are tight, but we still like it because of the location. Have a great trip.

Devils Tower
Many sites around Mt. Rushmore. Crazy Horse, Deadwood, take the Needles Highway.
Belle Fouche is geographic center of US.
Cody, WY has great museum.
Sept, you maybe able to get into Fishing Bridge with hookups. Or have to go into West Yellowstone
