With roughly 244,000 acres to wander, you will find something new with this changing landscape every visit.
The Badlands are an increasingly popular tourist destination, however, backpacking through, you can’t help but feel in awe of the desolate and untouched wilderness. Somewhat isolated, it’s one of those places where you can truly feel like you have room to breathe.
What to Expect on Castle Trail
For your backpacking and backcountry excursion, start at the west end of Castle Trail located on the Badlands Loop State Scenic Byway that runs through the park. Castle Trail is aptly named, as the pinnacles in the area resemble enormous sand castles. Start in the afternoon, so that you will be able to setup your campsite and take in a famous Badlands sunset.
The trail is a fairly easy out-and-back and, at just about 10 miles round-trip, it’s enough to get out and away from people and still see everything else that the Badlands have to offer. Backcountry camping is permitted anywhere, as long as your site is at least a half of a mile from any trail or road, and you aren’t visible from trails or roadways. During the spring, summer and fall, you can witness the galactic center of the Milky Way arching over the southern skies because of the decreased light pollution in the area. The next day, explore the other shorter trails that are at the east end of Castle Trail and then make your way back to the western trailhead.
Why Castle Trail?
Castle Trail is perfect if you like unusual landscapes, moderate distance and difficulty, and are up for backcountry camping on prairies instead of your typical mountain backcountry experience. If you plan to make it an overnight experience, make sure you can carry more than enough water to get you through hot days, as there are no water sources safe for filtering in the park. If you don’t like extreme temperature shifts, which are common in arid climates, you will probably other find day hikes much more enjoyable.
