The Door Trail at Badlands National Park in Interior, South Dakota is an easy 0.8 mile out-and-back hike through the Badlands. The main trail is a tiny quarter-mile boardwalk that leads through a break in the Badlands Wall known as "the Door" and to a view of the Badlands. After the quarter-mile boardwalk ends, the trail will continue, but there are no markers or blazes. From here you're free to wander the Badlands at your own risk, but be careful because there are numerous potholes and ledges.
There's only so much to see in the Badlands along this trail, but it's fun to go off the path and to explore the rock formations and ledges. This is one of the best hiking trails in Badlands National Park and it's a quick hit hike in the middle of the park.
Nearby Hikes: Be sure to check out the Notch Trail at the Badlands before heading out. The Notch Trail is a lot more fun than the Door Trail; however, the Notch Trail requires a ladder climb and a hike along a 30 to 40 foot ledge drop.
