If you only have an hour on foot in Badlands National Park, spend it on the Door, Window and Fossil Exhibit trails. All three are rated easy by the National Park Service and take about twenty minutes round trip: Door and Window are each about a quarter of a mile on a boardwalk, and the Fossil Exhibit loop is a little over a third of a mile. Door and Window start from the same parking area, so you can walk both in a single stop. The Door Trail steps through a gap in the wall of eroded buttes and then continues out onto a flat, signed route among the formations. The Window Trail ends at a viewing platform that looks through a natural opening in the rock toward a deep, striped canyon. The Fossil Exhibit Trail is a short loop with replicas and interpretive signs showing the kinds of animals whose remains came from these layers. None of the three requires special gear, although sun protection and water are essential.
The appeal is access. The boardwalks keep you above the fragile clay, hold steady even when the surface beside them is slick, and bring you quickly to viewpoints that would otherwise need a scramble. Door Trail's boardwalk is the more varied of the two, and its gap in the rock is a classic photograph; the signed route beyond it, which is marked with posts across the clay surface, offers a taste of walking among the formations for those who are comfortable on uneven ground.
Window Trail is the simplest and shortest, and it is a reliable place to see the layered rock in profile.
The Fossil Exhibit Trail adds a different dimension. Rather than showing you scenery, it explains the history of the place with signs and replica fossils of ancient mammals that lived here when the climate was wetter and warmer. It makes a good stop for children, because the animals are described in a language they enjoy: oversized relatives of modern animals, small saber-toothed hunters and sheep-like grazers. Since collecting fossils, rocks and plants inside the park is illegal, the exhibit trail is the place to enjoy them without taking them.
Timing matters more than difficulty here. These trails sit near the Big Badlands Overlook and the visitor center area, so they can be busy at midday in summer. Early morning gives you softer light, cooler temperatures and quieter boardwalks; late afternoon offers warm color and a good chance of seeing a bighorn sheep on the rocks nearby. Take water, a hat and sunglasses, stay on the boardwalk where it is provided, and respect any closure signs after rain or storms.

Good questions
How long are these trails?+
The National Park Service rates all three as easy. Door and Window are each about a quarter of a mile and take about 20 minutes round trip, and the Fossil Exhibit loop is a little over a third of a mile, also about 20 minutes.
Are the trails accessible?+
Door and Window start with boardwalks, and the Fossil Exhibit Trail is a boardwalk loop, which makes them among the easiest walks in the park. Check the park's accessibility information for current details, since conditions and surfaces can change.
Can I leave the boardwalk?+
The Door Trail has a marked route that continues beyond the boardwalk across natural surface, and it is meant for visitors who are comfortable on uneven ground. Stay on marked routes, avoid fragile slopes and never climb the formations.
What should I bring?+
Water, a hat, sunglasses and sunscreen, since there is little shade. Sturdy shoes help on the natural-surface portions. Cards, not cash, are needed at the entrance station.
When are the trails least crowded?+
Early morning and late afternoon. Midday in summer is the busiest and hottest time, and parking near the trailheads can fill up on peak days.
