On our way to the Black Hills, we will be staying overnight at Mitchell. On our way to Custer State Park, we would like to visit the Badlands. Would someone please let us know how much time should we spend at the Badlands. Besides Wall and Badlands Loop Road, what else is there to see? We have our reservations at Sylvan Lake that same evening. Would we be able to do the Badlands and still arrive at Sylvan Lake at a reasonable time? (I don't know when it gets dark there).
Thank you in advance for your input.
