This is one of those National Parks where you appreciate it most when you do research ahead of time and more planning. If you plan a trip here, I’d recommend finding a way to learn about Teddy Roosevelt and his presidency through a book or podcast as well as about General Custer and the Sioux before coming. Knowing the people who lived in these areas, those who fought there, and those who have tried to protect it makes the experience in the park much more worthwhile.
