I LOVE national parks and Badlands holds is a very unique place. I’ve never seen so much wildlife at any other national park as I did in one day at Badlands!
One of world’s oldest and most unique cave system is a must visit in South Dakota. Over 147 miles of caves surveyed but about 1,000 miles more to explore. Wind Cave has over 95% of world’s known Boxwork formation. Just make sure and buy a tour ticket early in the day.
