Please note that this is NOT the designated Sage Creek campground but the wilderness area that allows for very primitive tent camping. You park off of Rim Road where there is a small lot and a place to register (whether you're day-hiking or staying over night). You hike down into the high prarie and keep wide eye out for bison ( there are over 600 in the badlands!). Make sure that when you do come across wildlife, especially bison, that you give them ample space, do not appear aggressive and definitely don't try to pet them. You must hike in with your food and plenty of water, because the water in Sage Creek is not able to be filtered. It is very easy to spend hours and days exploring the beautiful land and jagged rock, but you must be prepared. From what we saw and what we researched, rarely do people go out and backpack and camp in this wilderness area. I would recommend this to only those who have enough experience backpacking and who know how to prepare themselves, as you will not be near any people or amenities.
