If you want to check out Jewel Cave, the closest place to camp will be Comanche Park Campground. After spending your days exploring the underground wonderland of this amazing cave system filled with sparkling crystals and magic, you’ll be so happy for a close place to crash among the tall pines, that you won’t even notice the nearby road that can be heard, or the close proximity to your neighbors. This spot is also close to Mt. Rushmore, and other national monuments and parks if you want to explore further. So in other words, it’s got loads of location points!
