If you've ever wanted to feel like you've been suddenly transported to another planet, go visit the amazingly unique Badlands National Park. With its odd rock formations and red landscape, the Badlands can offer an exotic adventure.

Actually, South Dakota has a lot to offer outdoor enthusiasts, including several popular man-made lakes and the legendary Black Hills caves, where spelunkers are challenged to the highest level. While there, also don't forget to check out Mt. Rushmore.
