  • Scenic Drives: For a short but very scenic drive inside the Park, take the Highway 240 Loop Road. The approximate time for this loop is 60 minutes.
  • Wildlife Viewing: One of the favorite things to do is to drive down the Sage Creek Rim Road to Robert’s Prairie Dog Town to see black-tailed prairie dogs "barking" their warnings and protecting their "town."  This is also your best route to have an opportunity to possibly see bison, bighorn sheep, coyotes, deer, eagles, hawks and foxes.
  • Hiking: There are several hiking trails in the Park. The majority of these are easy to moderate and allows the entire family to get out of the car and up close to the natural beauty of the Badlands National Park. For example –
    Door Trail
    This easy and accessible trail is only .75 miles roundtrip. The average time to complete the trail is 20 minutes. The trail leads through a break in the Badlands Wall known as “the Door” and to a view of the Badlands.
    Castle Trail
    This trail is moderate in difficulty and is 10 miles roundtrip. It is the longest trail in the Park. It is relatively level and is consider moderate primarily for its length. Plan on about 5 hour to complete this out and back hike.
    Medicine Root Loop
    This generally rolling spur trail connects with the Castle Trail and is 4 miles roundtrip. You will be able to explore the mixed grass prairie while enjoying views of the Badlands in the distance while hiking on this trail. The trail takes about 2 hours to complete.
  • Ranger Led Programs: Ranger led programs in the Badlands National Park include a night sky program which takes place from June to mid September, geology walk, fossil talk, prairie walk and especially for the kids, the Junior Ranger Program.
  • Camping: The Park has one developed campground, the Cedar Pass Campground which is located near the Ben Reifel Visitor Center. It has 96 sites and is a first come, first served campground. This campground has cold running water and flush toilets, but there are no showers. Further, it should be noted that open campfires are not permitted. Alternatively, you can stay at the single park lodge, Cedar Pass Lodge
