Badlands National Park is full of geological oddities, but the 1.5-mile-round-trip Notch Trail is one of the best treks in the South Dakota park. There's something distinctly eerie about the Badlands.

During my visits to Badlands National Park, I’ve seen Big-Horn Sheep and Pronghorn. This is one of those parks that you can visit in a few hours or a few days, depending on how much you want to do.
